Getting Started

Cryptocurrencies have dramatically transformed the way payments can be accepted over the internet and lowered the entry barrier for merchants to start getting paid. COINQVEST makes it simple to add cryptocurrency payments as a stand-alone solution or in addition to your existing checkout flows.

COINQVEST merchants benefit from all the advantages of a hosted software service. Using COINQVEST, it is no longer necessary to continuously monitor various blockchains for payment transactions. It allows you to focus on your core business while leaving the complexities of real-time blockchain settlement to us. COINQVEST creates cryptocurrency payment transactions on your behalf and automatically notifies you once the payment has been settled.

Customers can now pay you directly from their computers or mobile phones using their preferred cryptocurrency. COINQVEST converts incoming payments automatically into your cryptocurrency or fiat token of choice and deposits them to your account in your preferred form.

Using COINQVEST it is possible to accept payments in Bitcoin, Ethereum, Litecoin, Stellar Lumens or Ripple XRP but get paid in USD, EUR or any other supported currency instead.

The COINQVEST API provides a streamlined HTTP REST interface to integrate cryptocurrency payments into your online business or application. This API reference provides information on available endpoints and how to interact with them.

Using the COINQVEST API

Accepting cryptocurrency payments using the COINQVEST API is fast, secure, and easy. After you've signed up and obtained your API Key, all you need to do is create a checkout to get paid.

Creating an API Checkout

When you invoke the POST /checkout endpoint, COINQVEST generates and returns a list of payment methods (e.g. Bitcoin, Ethereum, Stellar Lumens etc.) along with the corresponding payment amount. Your customer selects his or her preferred blockchain and you then commit the checkout with POST /checkout/commit. COINQVEST now generates and returns the wallet address, which you display back to your customer for payment settlement. Using this method, you control the payment process entirely in your web application.

Creating a Hosted Checkout

To get started quickly we can alternatively provide you with a hosted checkout page you can send to your customers to complete the payment. Create a hosted checkout and retrieve the URL by invoking POST /checkout/hosted.

An example of how to dynamically create a hosted checkout and get paid:

Example Request

cURL 
curl -X POST https://www.coinqvest.com/api/v1/checkout/hosted \
-H "X-Digest-Key: YOUR_API_KEY" \
-H "X-Digest-Signature: DIGEST_AUTH_SIGNATURE" \
-H "X-Digest-Timestamp: TIMESTAMP" \
-d "@payload.json"

Where payload.json is a simple JSON object. Learn about authentication here.

Example Payload (minimal)

application/json 
{
   "charge":{
      "currency":"USD",
      "lineItems":[
         {
            "description":"T-Shirt",
            "netAmount":10.00
         }
      ]
   }
}

Above is the simplest form of creating a checkout. You submit a charge with exactly one line item at the cost of 10.00 USD. In the response the API returns an id along with a hosted checkout URL, which you display back to your customer in order for him or her to complete the payment.

Example Response

200 OK 
{
   "id":"b5bcf27e5482",
   "url":"https://www.coinqvest.com/en/checkout?id=b5bcf27e5482"
}

Once the payment is captured we notify you via WEBHOOK /payment. Alternatively you can poll GET /checkout for payment status updates.

If you prefer to control and host the entire checkout process in your own web application and branding instead, have a look at POST /checkout.

PRO Tip

You can inspect your API requests and the associated HTTP responses sent by COINQVEST in your .

Receiving Payments

Unlike credit card payments where merchants need to obtain credit card credentials in order to place a charge, cryptocurrency payments implement a push model where the customer must explicitly invoke the payment to send money to the merchant.

After creating a checkout, COINQVEST will continuously observe your customer's selected blockchain to monitor inbound payments. We set a 60 minute monitoring window for the payment to complete. If your customer does not complete the payment within that time frame, we mark the payment as expired.

Once the payment has been sent, your balance is credited, your dashboard automatically updated, and a webhook callback sent to your server, to automatically process the order in your system (WEBHOOK payment).

If you do not want to listen for webhook callbacks, you can monitor the GET /checkout endpoint by supplying the unique identifier that was provided when you created the checkout. Here is a simplified example:

Example Request

cURL 
curl 'https://www.coinqvest.com/api/v1/checkout?id=b5bcf27e5482' \
-H "X-Digest-Key: YOUR_API_KEY" \
-H "X-Digest-Signature: DIGEST_AUTH_SIGNATURE" \
-H "X-Digest-Timestamp: TIMESTAMP"

The endpoint returns an object with information about the current payment state, time to expiration and other parameters as specified in GET /checkout.

Authentication

Most requests to the COINQVEST API must be authenticated. The API endpoints are marked as public () or protected (). When accessing a protected endpoint your request must be authenticated with your API-Key using either the Basic-Auth or Digest-Auth method. The latter is more secure and recommended. Try the GET /auth-test endpoint to conveniently test your authentication implementation.

API-Key and API-Secret

Visit the API Settings to obtain your API-Key and API-Secret. You should also configure your preferred authentication method and enable "IP-address whitelisting" for increased security. If you ever feel that your API-Secret has been compromised, the settings allow you to roll a new one.

Digest-Auth

Digest-Auth is the recommended authentication method for accessing protected COINQVEST API endpoints. Every request must include the following headers: X-Digest-Key, X-Digest-Signature, and X-Digest-Timestamp, which are explained below.

Request

cURL 
curl 'https://www.coinqvest.com/api/v1/auth-test' \
-H "X-Digest-Key: YOUR_API_KEY" \
-H "X-Digest-Signature: DIGEST_AUTH_SIGNATURE" \
-H "X-Digest-Timestamp: UNIX_TIMESTAMP"

Request Headers

Key Type Description
X-Digest-Key string Your COINQVEST API Key. mandatory
X-Digest-Signature string Unique Digest-Auth Signature (see below). mandatory
X-Digest-Timestamp integer Current Unix timestamp (also see GET /time). mandatory

The X-Digest-Signature is generated by creating a SHA256 HMAC hash using your API-Secret as the shared secret in the message digest. The encrypted payload is composed as follows:
ENDPOINT_PATH . UNIX_TIMESTAMP . REQUEST_METHOD . REQUEST_BODY, where . represents string concatenation.

X-Digest-Signature Components

Component Type Description
ENDPOINT_PATH string The path of the endpoint that is being invoked, e.g. /auth-test in lower case.
UNIX_TIMESTAMP integer Current Unix timestamp. Must be less than 30 seconds old (also see GET /time).
REQUEST_METHOD string The request method, e.g. POST or GET in upper case.
REQUEST_BODY string The request body string. Only needed in POST, PUT, or DELETE requests. Set null for GET requests.

PHP Logo Code Example (PHP)

PHP 
$path = '/auth-test'
$timestamp = time();
$method = 'GET';
$body = $method == 'GET' ? null : json_encode($params);
$secret = 'YOUR_API_SECRET';

$signature = hash_hmac('sha256', $path . $timestamp . $method . $body, $secret);

Ruby Logo Code Example (Ruby)

Ruby 
require 'openssl'

path = '/auth-test'
timestamp = Time.now.to_i
method = 'GET'
body = method == 'GET' ? NIL : params.to_json
secret = 'YOUR_API_SECRET'

signature = OpenSSL::HMAC.hexdigest('sha256', secret, path + timestamp.to_s + method + body.to_s)

Ruby Logo Code Example (NodeJS)

NodeJS 
require('crypto');

let path = '/auth-test'
let timestamp = Date.now() / 1000 | 0;
let method = 'GET'
let body = method === 'GET' ? '' : JSON.stringify(params)
let secret = 'YOUR_API_SECRET'

let signature = crypto.createHmac('sha256', secret)
                .update(path + timestamp + method + body)
                .digest('hex');

View these examples if you're unsure how to create an HMAC SHA256 signature in your programming language.

Basic-Auth

Albeit simpler to implement, Basic-Auth is less secure than Digest-Auth and we recommend using the latter instead. By default COINQVEST API docs and examples always utilize Digest-Auth, but you can use Basic-Auth by replacing X-Digest headers with X-Basic, which is explained below:

Request

cURL 
curl 'https://www.coinqvest.com/api/v1/auth-test' \
-H "X-Basic: BASIC_AUTH_HASH"

Request Headers

Key Type Description
X-Basic string SHA256 hash over YOUR_API_KEY:YOUR_API_SECRET mandatory

Code Example

PHP 
$key = 'YOUR_API_KEY';
$secret = 'YOUR_API_SECRET';

$basicAuthHash = hash('sha256', $key . ':' . $secret);

IP Address Whitelisting

Use the API Settings to configure whether your API account can be accessed from any IP address or whitelisted IP addresses only. IP address whitelisting is recommended for production environments as it dramatically increases security. Withdrawal endpoints can only be accessed from whitelisted IP addresses.

POST/checkoutprotected

Invoking a checkout is the first step to get paid. This endpoint creates a white-label checkout, which you control entirely on your own platform UI or API. If you would like to create a hosted checkout with an automated payment page on COINQVEST servers, please use POST /checkout/hosted instead.

This endpoint takes a charge object, which includes line items, optional shipping costs or discounts and taxes. It can be optionally linked to a customer and lets you specify your desired settlement currency, which can be different from what the charge is denominated in and what your customer used for payment. Upon successful completion, the endpoint returns a list of payment methods and amounts, which you display back to your customer.

Your customer then selects his preferred payment method (e.g. Bitcoin) and you submit a new request with the selected blockchain and corresponding checkout id to POST /checkout/commit. Once a checkout is committed, our system starts monitoring the blockchain for inbound payment transactions and notifies you about payment events via WEBHOOK payment.

Checkouts are unique and not re-usable. You should create a new checkout for every charge.

Example Request

cURL 
curl -X POST https://www.coinqvest.com/api/v1/checkout \
        -d "@payload.json"

Where payload.json is a JSON object.

Example Payload (Minimal)

application/json 
{
   "charge":{
      "currency":"USD",
      "lineItems":[
         {
            "description":"T-Shirt",
            "netAmount":10.00
         }
      ]
   }
}

Explanation of Above Payload Configuration

Above is the minimal configuration required to initiate a checkout. The charge is denominated in "USD" and has exactly one line item at a cost of USD 10.00. The required payment amount in BTC, ETH, XLM, etc. given in the API response is calculated against the total payment amount and currency given here.

Example Payload (Full)

application/json 
{
   "charge":{
      "customerId":"716dad4c5e5f",
      "currency":"USD",
      "lineItems":[
         {
            "description":"T-Shirt",
            "netAmount":10,
            "quantity":1,
            "productId":"P1234"
         }
      ],
      "discountItems":[
         {
            "description":"Loyalty Discount",
            "netAmount":0.5
         }
      ],

      "returnUrl":"https://www.merchant.com/path/to/complete/checkout"
   }
}

Request Params (POST)

PRO Tip #1 Auto-Conversion

Make sure to set the settlementCurrency parameter to automatically convert incoming funds into your preferred currency, e.g. USD.

PRO Tip #2 Customer Object Relation

Provide a charge.customerId as given by POST /customer to automatically link the checkout to a customer. Linking payments with customers helps with your accounting, provides more details in your transaction history and allows you to send out automated invoices and payment status notifications.

PRO Tip #3 Total Amount Formula

The total amount calculation is executed using the following formula.
$net = sum($lineItems) - sum($discountItems) + sum($shippingCostItems)
$taxableSum = $net - sum($shippingCostItems) + sum($taxableShippingCostItems)
$total = $net + ($taxableSum * sum($taxItems))

Key Type Description Default Mandatory
charge{} object This is the core information needed to create a checkout. It provides a charge object, which describes what products or services you want to bill, optional shipping and handling costs, discounts and tax information. It also links this checkout to a customer. null mandatory
.customerId string(12) Specifies the customer to which this charge relates to. Us the identifier as given by POST /customer. This links the charge to your customer, which helps with your accounting, provides more details in your transaction history and enables invoicing and status update emails to your customer. null optional
.currency string The customer facing currency in which this charge is denominated in, e.g. USD or EUR. Valid values are any fiat currency or blockchain identifiers supported by COINQVEST, such as

* an assetCode given by GET /fiat-currencies
* or a nativeAssetCode as given by GET /blockchains.

Alternative expert setting: You may use a specific asset id as given by GET /assets. For example, if you want to calculate payment amounts against AnchorUSD's market, you'd use that asset's identifier specifically, otherwise the platform default for each fiat currency or blockchain is used.

Unless a different asset code is specified in settlementCurrency (see below) this is also the currency you're paid in. 		null mandatory
.lineItems{} object An object providing payment amounts and details about the charged products or services. null mandatory
.description string The product or service description as plain text (Unicode). Maximum of 200 characters. null mandatory
.netAmount numeric The net cost for this item in the currency provided in charge.currency. null mandatory
.quantity integer The quantity of this item. If you provide a quantity n then the resulting total amount charged will be n * netAmount 1 optional
.productId string An optional product id to link this item with a corresponding relation in your own database. Maximum of 20 characters. null optional
.discountItems{} object An optional object listing any potential discounts related to this payment request. null optional
.description string The discount description as plain text (Unicode). Maximum of 200 characters. null mandatory
.netAmount numeric The net amount for this discount in the currency provided in charge.currency. null mandatory
.shippingCostItems{} object An optional object listing any potential shipping and handling costs related to this payment request. null optional
.description string The shipping or handling cost description as plain text (Unicode), e.g. "Shipping Costs". Maximum of 200 characters. null mandatory
.netAmount numeric The net amount of this shipping cost in the currency provided in charge.currency. null mandatory
.taxable boolean Indicates whether this shipping cost is taxable. If set to true then tax calculation includes this item. false optional
.taxItems{} object An optional object listing any potential taxes related to this payment request. null optional
.name string The applied tax or tax identifier, e.g. "SALES TAX". null mandatory
.percent numeric The percentage of the applied tax in decimal notation, e.g. 0.0825 to represent a tax rate of 8.25% null mandatory
.settlementCurrency string This specifies the currency you'll be credited in when the payment completes. For example, if you specify USD as settlement currency then you will be credited in USD. Otherwise you will be credited in the currency specified in the charge (see above). It is possible to select a settlement currency, which is different from the customer facing currency.

Valid values are any fiat currency or blockchain identifiers supported by COINQVEST, such as

* an assetCode given by GET /fiat-currencies
* or a nativeAssetCode as given by GET /blockchains.

Alternative expert setting: You may use a specific asset id as given by GET /assets. For example, if you want to be credited in AnchorUSD tokens, you'd use that asset's identifier specifically, otherwise the platform default for each fiat currency or blockchain is used. 		null mandatory
.webhook string A webhook URL on your server that listens for payment events as specified in WEBHOOK payment. null optional
.blockchainRelays{} object An optional key-value list of your preferred asset issuers. It specifies which asset issuer should be used to process incoming payments from the Bitcoin, Ethereum, Litecoin or XRP Ledger networks. If no asset issuers are specified then the platform defaults are used.

The object contains blockchain identifiers (GET /blockchains) as attribute keys and the id as given by GET /asset-issuers as item value. 		null optional
.links{} object An object specifying URLs with information on where to send the customer if he wishes to cancel the checkout process or when the payment successfully completed. null optional
.cancelUrl string Specifies where to send the customer when he wishes to cancel the checkout process.

This is typically the checkout page in your web application or a shopping cart view.

The checkout id, as given in above response, is automatically appended as GET parameter checkoutId to facilitate mapping in your application. You can specify custom GET parameters alternatively. 		null optional
.returnUrl string Specifies where to send the customer when the payment successfully completed.

To prevent spoofing, it is very important for your server to make a call to GET /checkout to confirm the receipt of payment whenever this URL is invoked. Alternatively you can rely on WEBHOOK payment.

The checkout id, as given in above response, is automatically appended as GET parameter checkoutId to facilitate mapping in your application. You can specify custom GET parameters alternatively. 		null optional

Success Response Attributes

Name Type Description Nullable
.id string(12) The identifier of the checkout. You should store this persistently to match payments and associated information against this checkout. false
.paymentMethods[] array Contains a list of available payment methods for this checkout and associated payment amounts for your customer. Currently COINQVEST supports payments in BTC, ETH, LTC, XRP, XLM and any other asset on the Stellar Network in the form of path payments (to XLM).

This list should be displayed back to your customer, who then selects the desired blockchain as payment method. Upon selection, your application submits a POST /checkout/commit and obtains the deposit information and required for your customer to make the payment.

This list includes all blockchains listed in GET /blockchains that are above the minimum payment threshold. Some blockchains have high fees and might not appear in the list for payments with low payment amounts. Stellar Lumens XLM and Ripple XRP are always available. 		false
.assetCode string(3) The asset code of the payment currency, e.g. BTC. Inspect GET /blockchains for a list of supported blockchains. Submit this assetCode along with the checkoutId to the POST /checkout-commit endpoint to obtain deposit information for your customer. false
.blockchain string(12) The blockchain name in plain text. false
.paymentAmount string The required payment amount to display back to your customer. false

Next Step

Your application displays the payment methods received in the response back to your customer. The customer then selects his preferred payment method and your server submits this selection in a new API request to the POST /checkout/commit endpoint. In return you receive the deposit address for the selected blockchain for display to your customer. Continue here.

Error Response application/json

4xx/5xx 
{
    "errors":[
        "Service unavailable."
    ]
}

Error Response Params

Name Type Description Nullable
errors[] string[ ] A list of strings explaining the error. false

POST/checkout/commitprotected

This endpoint is a continuation of the checkout process started in POST /checkout. If you aren't familiar with how to initialize a checkout process yet, please start here.

This endpoint takes a checkoutId and an assetCode as given by POST /checkout. Upon successful completion, it returns deposit information, which is displayed back to your customer in order for him or her to make the payment.

When the payment completes your server is automatically notified via WEBHOOK payment. Alternatively you can poll GET /checkout for payment updates after you displayed the deposit information to your customer.

In the previous step POST /checkout has given you a list of payment methods, like this:

Example Response (as given by POST /checkout)

200 OK 
{
   "id":"6d55626309d6",
   "paymentMethods":[
      {
         "assetCode":"XLM",
         "blockchain":"Stellar Network",
         "paymentAmount":"165.7007861"
      },
      {
         "assetCode":"BTC",
         "blockchain":"Bitcoin",
         "paymentAmount":"0.0011102"
      },
      {
         "assetCode":"ETH",
         "blockchain":"Ethereum",
         "paymentAmount":"0.0440141"
      }
   ]
}

As a prerequisite to invoke this endpoint you should have received a response as above from POST /checkout. It contains a list of payment methods, which you display back to your customer to choose from. Upon selection, you invoke POST /checkout/commit (this endpoint) with the selected assetCode and checkoutId to receive deposit information for your customer to make the payment.

Request

Where payload.json is a JSON object.

Example Payload

application/json 
{
  "checkoutId":"6d55626309d6",
  "assetCode":"ETH"
}

Request Params

Key Type Description Default Mandatory
checkoutId string(12) Unique identifier as given by POST /checkout. null mandatory
assetCode string(3) The asset code related to the payment method selected by your customer, e.g. ETH if your customer wishes to pay using the Ethereum blockchain. null mandatory

Example Success Response for ETH application/json

200 OK 
{
   "depositInstructions":{
      "blockchain":"Ethereum",
      "assetCode":"ETH",
      "amount":"0.0056804",
      "address":"0xc85eBb197c8212C09B7d0905C3ce9e3fCe324F0B",

   },
   "expirationTime":"2020-02-26T18:49:33+00:00",
   "checkoutId":"29d030183ce9"
}

When you customer selects Bitcoin (BTC), Ethereum (ETH) or Litecoin (LTC) as their payment method of choice, the only relevant fields are address and amount. The response fields for memo, memoType and destinationTag are null and irrelevant in these cases. You don't need to display them to the customer.

Example Success Response for XLM application/json

200 OK 
{
   "depositInstructions":{
      "blockchain":"Stellar Network",
      "assetCode":"XLM",
      "amount":"17.8639906",
      "address":"GASKYWPPQ2VSO6KNIPIRVXMSSDGZLYZQ67CDTLVXOXYDG26SPZ66EDCQ",
      "memo":"snowy-hills",
      "memoType":"text",

   },
   "expirationTime":"2020-02-26T18:48:58+00:00",
   "checkoutId":"d95114c52bca"
}

When your customers select XLM as their payment currency then you need to provide them with the address as well as memo and memoType. This is important in order for COINQVEST to map the payment to your merchant account. The destinationTag field is null and irrelevant for XLM payments and can be ignored.

Example Success Response for XRP application/json

200 OK 
{
   "depositInstructions":{
      "blockchain":"XRP Ledger",
      "assetCode":"XRP",

      "destinationTag":"15918"
   },
   "expirationTime":"2020-02-26T18:48:30+00:00",
   "checkoutId":"1ff5df8ed792"

When your customer selects XRP as the payment currency then you need to provide him or her with the address as well as the destinationTag. This is important in order for COINQVEST to map the payment to your merchant account. The memo and memoType fields are null and irrelevant for XRP payments and can be ignored.

.depositInstructions{} object The deposit information to display to your customer. false
.blockchain string The selected blockchain name as plain text. false
.assetCode string(3) The selected payment asset code, e.g. BTC, ETH, XLM, LTC or XRP. false
.amount string The required payment amount for the selected blockchain. Display this back to your customer. Please note that this field is of type string even though it is numeric. You might need to do some type casting here. false
.memo string This field is only relevant for payments in XLM. Otherwise it is null. If the assetCode is XLM, it is extremely important to display this back to your customer alongside the deposit address because it is needed to map the payment to your merchant account. true
.memoType string This field is only relevant for payments in XLM. Otherwise it is null. If the assetCode is XLM, it is extremely important to display this back to your customer alongside the deposit address because it is needed to map the payment to your merchant account. true
.destinationTag string This field is only relevant for payments in XRP. Otherwise it is null. If the assetCode is XRP, it is extremely important to display this back to your customer alongside the deposit address because it is needed to map the payment to your merchant account. true
.expirationTime timestamp W3C formatted timestamp with the expiration time for this checkout. COINQVEST allows for a 60 minute window to complete the payment, afterwards we mark the charge as expired. Don't worry though, you will still be credited even if the payment arrives late. false
.checkoutId array The checkout id as originally given by POST /checkout. false

Next Step

You display the deposit information back to your customer. Meanwhile COINQVEST starts monitoring the blockchain address given in the API response above and notifies you automatically via WEBHOOK payment when a payment completes. Alternatively you can poll GET /checkout for payment updates after you displayed the deposit information to your customer.

POST/checkout/hostedprotected

Hosted checkouts are the simplest form of getting paid using the COINQVEST platform. This API endpoint creates and returns a URL for a hosted checkout page on COINQVEST servers. If you would like to maintain control of the UI and entire checkout process yourself, please use the POST /checkout endpoint instead.

Using this endpoint, your server submits a set of parameters, such as the payment details including optional tax items, customer information, and settlement currency. Your server then receives a checkout URL in return, which is displayed back to your customer.

Upon visiting the URL, your customer is presented with a checkout page hosted on COINQVEST servers. This page displays all the information the customer needs to complete payment. When completed, your application is automatically notified via WEBHOOK payment. Alternatively you can poll GET /checkout to query information about the payment state.

COINQVEST hosted checkouts implement responsive design and are suitable for mobile phone screens as well as desktop environments with large monitors.

Hosted checkout URLs are unique and not re-usable. You should issue a new URL for every charge.

Request Params (POST)

PRO Tip #1 Auto-Conversion

Make sure to set the settlementCurrency parameter to automatically convert incoming funds into your preferred currency, e.g. USD.

PRO Tip #2 Customer Object Relation

Provide a charge.customerId as given by POST /customer to automatically link the checkout to a customer. Linking payments with customers helps with your accounting, provides more details in your transaction history and allows you to send out automated invoices and payment status notifications.

PRO Tip #3 Total Amount Formula

The total amount calculation is executed using the following formula.
$net = sum($lineItems) - sum($discountItems) + sum($shippingCostItems)
$taxableSum = $net - sum($shippingCostItems) + sum($taxableShippingCostItems)
$total = $net + ($taxableSum * sum($taxItems))

Key Type Description Default Mandatory
charge{} object This is the core information needed to create a checkout. It provides a charge object, which describes what products or services you want to bill, optional shipping and handling costs, discounts and tax information. It also links this checkout to a customer. null mandatory
.customerId string(12) Specifies the customer to which this charge relates to. Us the identifier as given by POST /customer. This links the charge to your customer, which helps with your accounting, provides more details in your transaction history and enables invoicing and status update emails to your customer. null optional
.currency string The customer facing currency in which this charge is denominated in, e.g. USD or EUR. Valid values are any fiat currency or blockchain identifiers supported by COINQVEST, such as

* an assetCode given by GET /fiat-currencies
* or a nativeAssetCode as given by GET /blockchains.

Alternative expert setting: You may use a specific asset id as given by GET /assets. For example, if you want to calculate payment amounts against AnchorUSD's market, you'd use that asset's identifier specifically, otherwise the platform default for each fiat currency or blockchain is used.

Unless a different asset code is specified in settlementCurrency (see below) this is also the currency you're paid in. 		null mandatory
.lineItems{} object An object providing payment amounts and details about the charged products or services. null mandatory
.description string The product or service description as plain text (Unicode). Maximum of 200 characters. null mandatory
.netAmount numeric The net cost for this item in the currency provided in charge.currency. null mandatory
.quantity integer The quantity of this item. If you provide a quantity n then the resulting total amount charged will be n * netAmount 1 optional
.productId string An optional product id to link this item with a corresponding relation in your own database. Maximum of 20 characters. null optional
.discountItems{} object An optional object listing any potential discounts related to this payment request. null optional
.description string The discount description as plain text (Unicode). Maximum of 200 characters. null mandatory
.netAmount numeric The net amount for this discount in the currency provided in charge.currency. null mandatory
.shippingCostItems{} object An optional object listing any potential shipping and handling costs related to this payment request. null optional
.description string The shipping or handling cost description as plain text (Unicode), e.g. "Shipping Costs". Maximum of 200 characters. null mandatory
.netAmount numeric The net amount of this shipping cost in the currency provided in charge.currency. null mandatory
.taxable boolean Indicates whether this shipping cost is taxable. If set to true then tax calculation includes this item. false optional
.taxItems{} object An optional object listing any potential taxes related to this payment request. null optional
.name string The applied tax or tax identifier, e.g. "SALES TAX". null mandatory
.percent numeric The percentage of the applied tax in decimal notation, e.g. 0.0825 to represent a tax rate of 8.25% null mandatory
.settlementCurrency string This specifies the currency you'll be credited in when the payment completes. For example, if you specify USD as settlement currency then you will be credited in USD. Otherwise you will be credited in the currency specified in the charge (see above). It is possible to select a settlement currency, which is different from the customer facing currency.

Valid values are any fiat currency or blockchain identifiers supported by COINQVEST, such as

* an assetCode given by GET /fiat-currencies
* or a nativeAssetCode as given by GET /blockchains.

Alternative expert setting: You may use a specific asset id as given by GET /assets. For example, if you want to be credited in AnchorUSD tokens, you'd use that asset's identifier specifically, otherwise the platform default for each fiat currency or blockchain is used. 		null mandatory
.webhook string A webhook URL on your server that listens for payment events as specified in WEBHOOK payment. null optional
.blockchainRelays{} object An optional key-value list of your preferred asset issuers. It specifies which asset issuer should be used to process incoming payments from the Bitcoin, Ethereum, Litecoin or XRP Ledger networks. If no asset issuers are specified then the platform defaults are used.

The object contains blockchain identifiers (GET /blockchains) as attribute keys and the id as given by GET /asset-issuers as item value. 		null optional
.links{} object An object specifying URLs with information on where to send the customer if he wishes to cancel the checkout process or when the payment successfully completed. null optional
.cancelUrl string Specifies where to send the customer when he wishes to cancel the checkout process.

This is typically the checkout page in your web application or a shopping cart view.

The checkout id, as given in above response, is automatically appended as GET parameter checkoutId to facilitate mapping in your application. You can specify custom GET parameters alternatively. 		null optional
.returnUrl string Specifies where to send the customer when the payment successfully completed.

To prevent spoofing, it is very important for your server to make a call to GET /checkout to confirm the receipt of payment whenever this URL is invoked. Alternatively you can rely on WEBHOOK payment.

The checkout id, as given in above response, is automatically appended as GET parameter checkoutId to facilitate mapping in your application. You can specify custom GET parameters alternatively. 		null optional

Next Step

Your application analyzes the API response and determines whether it wants to accept the guaranteed targetAmount. To finalize the withdrawal, you confirm it by invoking the POST /withdrawal/commit endpoint.

POST/withdrawal/commitprotected

This endpoint is a continuation of the withdrawal process started in POST /withdrawal. If you aren't familiar with how to initialize a withdrawal process yet, please start here.

This endpoint takes a withdrawalId parameter as given by POST /withdrawal. Upon successful completion, the withdrawal is committed and processed by COINQVEST. Its state changes from PENDING_API_COMMIT to COMPLETED in the response.

In the previous step POST /withdrawal has given you an object, like this:

Example Response (as given by POST /withdrawal)

   "withdrawal":{
      "id":"12d72c3c8145",

         "nuban":"4791494548",
         "bankName":"FirstBank"
      }
   }
}

As a prerequisite, to invoke this endpoint you should have received a response as above from POST /withdrawal. Its state is PENDING_API_COMMIT, which means it is awaiting final confirmation through this endpoint. Upon inspection and acceptance of the given targetAmount, you invoke POST /withdrawal/commit (this endpoint) to confirm the withdrawal and submit it for processing.

GET/asset-issuersprotected

Returns a list of asset issuers supported by the COINQVEST platform. Assets represent a crypto or fiat currency and exist as tokens on the Stellar Network. Asset issuers are the regulated financial institutions, companies or other entities that bring assets on and off the network.

Whenever you receive a payment, funds are tokenized on the Stellar Network and credited to your account. When you make a withdrawal, funds are de-tokenized and converted back into their true form, e.g. money in your bank account or funds on the native Bitcoin blockchain.

Asset issuers are responsible for tokenizing and de-tokenizing assets during customer checkouts and withdrawals from the COINQVEST platform.

If you have a preference you can explicitly specify asset issuers during checkout and withdrawal, otherwise the platform default or the most economic option for you is automatically selected.

GET/auth-testprotected

Similar to the GET /ping endpoint except this requires authentication.

A good starting place to test your Basic-Auth or (recommended) Digest-Auth implementation. The below example demonstrates a Digest-Auth request. This endpoint accepts Basic-Auth but it is discouraged for production environments. To use Basic-Auth, replace the X-Digest headers with the X-Basic one (see Authentication).

Request

cURL 
curl 'https://www.coinqvest.com/api/v1/auth-test' \
-H "X-Digest-Key: YOUR_API_KEY" \

-H "X-Digest-Timestamp: UNIX_TIMESTAMP"

Request Headers

Key Type Description
X-Digest-Key string Your COINQVEST API Key
X-Digest-Signature string Unique Digest-Auth signature (see authentication)
X-Digest-Timestamp integer Current Unix timestamp (also see GET /time).

POST/customerprotected

Creates a customer object, which can be associated with checkouts, payments, and invoices. If a customer with the given email address already exists an update is performed. This endpoint can therefore be used as an alternative to PUT /customer.

Checkouts associated with a customer generate more transaction details, help with your accounting, and can automatically generate invoices for your customer and yourself.

The Merchant API implements endpoints to create (POST /customer), delete (DELETE /customer), and update (PUT /customer) your customers. You can also retrieve individual customers (GET /customer) as well as fetch a list of all your customers (GET /customers).

Example Request

cURL 
curl -X POST https://www.coinqvest.com/api/v1/customer \
-d "@payload.json"

Where payload.json is a JSON object.

WEBHOOKpayment

Webhooks are responsible for posting information back to your server when certain events happen. They are sometimes called "callbacks". This webhook is invoked when a payment by your customer is successful and your account is credited.

You specify the webhook endpoint on your server in the initial call to POST /checkout or POST /checkout/hosted.

Once the checkout has been triggered, we start monitoring the payment blockchain for your customers payment. When we detect the payment and credit your account, we send an HTTP POST request to your server as specified below. Using the webhook, you can extract the payment information from the HTTP request body and mark the sale as completed in your system.

If you don't want to listen for webhooks on your server you can alternatively poll GET /checkout to obtain equivalent information as given by this webhook.

Webhook Payload Headers

HTTP Request Headers 
POST / HTTP/1.1
User-Agent: COINQVEST Webhook Engine 1.0.0
Host: www.merchant.com

Content-Length: 532

PRO Tip

To add additional security to your endpoint and prevent spoofing, we recommend to parse the X-Webhook-Auth header and verify its value.

You can verify the request was sent by COINQVEST by creating a hash hash('sha256', YOUR_API_SECRET . WEBHOOK_REQUEST_BODY) (where the . symbol represents concatenation) and matching it against the header value.

  "customerId": "1acf0d0b10bd",
  "checkoutId": "87508a7a78c3"
}

IMPORTANT

Your endpoint should always invoke GET /checkout and inspect the state field in its response when processing a payment webhook. It is safest to credit your customer only when you confirm the state of the related checkout is COMPLETED.

This way, you protect yourself from unlikely situations when you receive a WEBHOOK payment for partial payments, underpaid amounts, or other exceptions.

Send 200 OK

Your server needs to respond with a status code of 200 in the HTTP response when it successfully parses the webhook payload. Otherwise, our system will keep sending webhook requests for up to 48 hours in increasing intervals until we detect a 200 status code.

PRO Tip

You can inspect webhook requests sent by COINQVEST along with your associated server responses in your .
