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 or blockchain deposit address on Bitcoin, Lightning, Litecoin, Stellar, or other supported networks to get paid. You can also use the API for fiat on- and off-ramping via SWIFT or SEPA.

Wallets and Deposits

Your COINQVEST account comes equipped with dedicated deposit addresses for Bitcoin, Lightning, Litecoin, Stellar, SWIFT, SEPA, and other supported networks. You can receive blockchain payments within seconds after registering. The GET /wallets and POST /deposit-address endpoints return your blockchain addresses to start receiving custom deposits.

Checkouts

COINQVEST checkouts provide fast and convenient ways for your customers to complete payment. We built a great user experience with hosted checkouts that can be fully branded. If you're not into payment pages, you can take full control over the entire checkout process using our backend checkout APIs. Click here to learn more about building checkouts.

Swaps and Transfers

Once funds arrive in your account, either via completed checkouts or custom deposits, you have instant access to them and the ability to swap them into other assets or transfer them to your bank account or other blockchain accounts (we recommend to always forward funds into self-custody on cold storage). The POST /swap and POST /transfer endpoints will get you started on swaps and transfers.

Financial Reports and Accounting

We don't leave you hanging with an obscure and complicated blockchain payment trail to figure out by yourself. All transactions on COINQVEST are aggregated into the Financial Reports section of your account and can even be associated with counter-parties, such as customers and beneficiaries. We provide CSV reports, charts, and beautiful analytics for all your in-house accounting needs.

Software Development Kits

The COINQVEST API works with any REST client in any programming language and we've published SDKs for PHP, Ruby, and NodeJS on our GitHub to help you get started quickly.

Building Checkouts

The first step to get started is to decide whether you want to use our hosted checkout experience (which can be fully branded) or implement self-hosted checkouts where you control the entire payment process on your own servers via our backend APIs.

Creating Backend API Checkouts

COINQVEST APIs enable you to fully control and host the entire checkout process in your own web application and branding. Choose self-hosted checkouts if you want your users to stay within your application without being redirected to COINQVEST to complete payment. Use the POST /checkout API endpoint to get started with whitelabel payments.

Creating Hosted Checkouts with Payment Links

Hosted checkouts can be fully branded and are the simplest form of getting paid using the COINQVEST platform. The POST /checkout/hosted API endpoint creates and returns a payment link to a checkout page on coinqvest.com or your own domain via Brand Connect. Your application retrieves the checkout URL and directs your customer to the hosted checkout page to complete payment.

Here is an example of how to dynamically create a hosted checkout and get paid:

Example Request

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 "@charge.json"

Where authentication is supplied via HTTP headers and charge.json is a JSON object:

Example Charge (minimal)

{
   "charge":{
      "billingCurrency":"USD",
      "lineItems":[
         {
            "description":"PCI Graphics Card",
            "netAmount":169.99
         }
      ]
   },
   "settlementAsset":"USDC:GA5ZSEJYB37JRC5AVCIA5MOP4RHTM335X2KGX3IHOJAPP5RE34K4KZVN"
}

Above example creates a charge for an item at 169.99 EUR. You can configure more details, such as shipping costs, discounts, taxes, the related customer, as well as your preferred settlement asset as documented here.

Example Response (application/json)

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

The API returns a unique identifier along with a hosted checkout URL, which you display back to your customer in order for him or her to complete payment. Once the funds are captured we notify you via WEBHOOK checkout-completed.

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 continuously observes 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 (but still accept payment if it arrives delayed).

Once the payment has been received, 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 checkout-completed).

Example Webhook (application/json)

{
   "eventType":"CHECKOUT_COMPLETED",
   "data":{
      "checkout":{
         "id":"efd667b61725",

                  {
                     "description":"PCI Graphics Card",
                     "quantity":"1",
                     "netAmount":"169.99",
                     "productId":"P1234"
                  }
               ],
               "billingCurrency":"USD",
               "customerId":"a2df67b61725"
            },
            "settlementAsset":"USDC:GA5ZSEJYB37JRC5AVCIA5MOP4RHTM335X2KGX3IHOJAPP5RE34K4KZVN"
         }
      }
   }
}

The webhook contains a JSON object in the HTTP request body and informs you about incoming payments and their attributes as specified in WEBHOOK checkout-completed. In above example the customer paid in ETH and the merchant got credited in USD.

Brand Connect

Brand Connect customizes COINQVEST's hosted checkouts to your own brand, web domain, custom logo, images, and fully skinned UI. It can run on coinqvest.com or on your own web domain with a simple docker container deployment.

Brand Connect specifically caters to payment service providers who want to take advantage of COINQVEST's all-in-one checkout flow under their own corporate identity, including all its perks, such as exception handling for overpaid, underpaid, multiple transactions, refunds, or customer management. Of course we won't stop you if you are not a payment service provider and simply want to make your online shop's checkout page match your website's overall look and feel.

Brand Configuration

You can configure the appearance of your checkouts via our Brand Connect web interface in your account settings. Follow these steps to get your custom branding up and running.

1. Enable Brand Connect in your account settings
2. Continue in account settings to configure Brand Information, Images, Fonts, and Colors

Your checkout pages are now customized with your company's company logo, favicon, custom crypto images, font types, and your very own color scheme. When you inspect your checkout pages you will notice that your custom UI skin is already applied and there is no mention of COINQVEST being your service provider.

Domain Name Configuration

By default your custom branding runs on the coinqvest.com web domain, but you can choose to make your checkouts accessible through your very own web domain instead. This is particularly useful if you provide payment services to your clients and want to use COINQVEST but host the checkout flow in your own web application or APIs and maintain the full appearance of your own corporate identity.

Web domain integration is implemented by deploying the Brand Connect docker container (GitHub) into your own hosting environment and pointing your desired custom web domain at it via DNS config. The docker container acts as a proxy for HTTP traffic between the public and the COINQVEST servers and enables your custom branded UI. Follow these steps to host checkouts under your own domain.

1. Enable Brand Connect in your account settings
2. Continue in account settings to configure Brand Information, Images, Fonts, and Colors
3. Specify the web domain for your checkouts and obtain your CQ_BRANDING_KEY (by completing the steps above)
4. Deploy the Brand Connect docker container by with your own SSL certificate
5. Point your web domain's DNS configuration at the IP address you're running the docker container on.

That's it. Your COINQVEST checkout pages now live on your very own web domain and are fully integrated with your corporate identity's look and feel. Read more on GitHub.

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 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 '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.

Code Example (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);

Code Example (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)

Code Example (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

You can choose to use a basic authentication header, which is easier to implement (as it's a static hash over your API key and secret) but less secure than Digest-Auth. We recommend use Basic-Auth during development or in test environments only.

Request

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

$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 self-hosted checkout on your server, 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 checkout-completed.

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

Example Request

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

Where payload.json is a JSON object.

Example Payload (Minimal)

{
   "charge":{
      "billingCurrency":"EUR",

}

Explanation of Above Payload Configuration

Above is the minimal configuration required to initiate a checkout. The charge is denominated in EUR and has exactly one line item at a cost of 169.99 EUR. The payment amount charged to by your customer in his crypto of choice is calculated against the total billing amount specified here.

Request Params (POST)

PRO Tip #1 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 #2 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))

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 a networkId 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 checkout-completed. 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:

Next Step

You display the deposit information back 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 checkout-completed. 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. You can modify their appearance to match your corporate identity by using Brand Connect.

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

Request Params (POST)

PRO Tip #1 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 #2 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))

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.

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

Where payload.json is a JSON object.

Example Payload

{
   "customer":{

Webhook Concepts

Webhooks are responsible for posting information back to your server when certain events happen. Such events include completed payments or payment exceptions when the checkout was underpaid for example.

Webhooks are crucial if you want to automate certain workflows within your application as they enable you to trigger procedures, such as marking a customer checkout as completed and initiating the shipping of goods or services.

Specifying the Webhook URL

The webhook URL on your server is specified in your initial API call to POST /checkout, POST /checkout/hosted, or POST /deposit-address. You can provide default webhook URLs in your API settings as well (if given in API calls they override the default). When supplying a webhook URL our system automatically notifies you via HTTP POST when certain events occur.

Webhook Events

A webhook event is triggered and sends an HTTP POST request to your server when a checkout successfully completes (WEBHOOK checkout-completed) or an exception occurs, such as the customer underpaying (WEBHOOK checkout-underpaid). We'll be adding more webhook events in the future so check back often. You can see a find a list of webhook events in the menu on the left hand side.

Webhook Structure

A webhook is a standard HTTP POST request sent from us to your server. The request includes HTTP headers, which can help you verify that it was sent by us, and an HTTP body that contains the actual data payload, such as the webhook event type and associated information.

Webhook Payload Headers

POST / HTTP/1.1
User-Agent: COINQVEST Webhook Engine 1.0.1
Host: www.merchant.com
Accept: */*
Content-Type: application/json

Content-Length: 532

Webhook Payload Body

{
  "eventType": "CHECKOUT_COMPLETED",
  "data": {...}
}

Webhook Payload Attributes

Name	Type	Description	Nullable
`.eventType`	string	Indicates the webhook event type. Different types have different payloads and you should implement a parser for each event type. Valid types are: `CHECKOUT_COMPLETED`, `CHECKOUT_UNDERPAID`, `UNDERPAID_ACCEPTED`, `DEPOSIT_PENDING`, `DEPOSIT_COMPLETED`, `SWAP_COMPLETED`, `SWAP_FAILED`, `TRANSFER_COMPLETED`, `TRANSFER_FAILED`.	false
`.data`	string	An object containing the payload associated with this event type.	false

Parsing Webhook Payloads

Webhook payloads differ between event types. Your system should inspect the eventType and implement a parser for each event type you want to support.

Example: Parsing Based on Event Type (PHP)

$payload = json_decode(file_get_contents("php://input"), true);
$type = $payload['eventType'];
$data = $payload['data'];

switch($type) {
    case('CHECKOUT_COMPLETED'):
        // do something when a checkout was successfully completed (and your account is credited)
        break;
    case('CHECKOUT_UNDERPAID'):
        // do something when a checkout was underpaid (and your account is not credited yet)
        break;
    case('UNDERPAID_ACCEPTED'):
        // do something when an underpaid checkout was manually accepted (and your account is credited)
        break;
    case('DEPOSIT_PENDING'):
        // do something when a deposit was detected on chain but is still unconfirmed (and your account is not credited yet)
        break;
    case('DEPOSIT_COMPLETED'):
        // do something when a deposit completed (and your account is credited)
        break;
    case('SWAP_COMPLETED'):
        // do something when a swap completed (and funds in your account are exchanged)
        break;
    case('SWAP_FAILED'):
        // do something when a swap failed (and no funds are affected)
        break;
    case('TRANSFER_COMPLETED'):
        // do something when a transfer completed (and your account is debited)
        break;
    case('TRANSFER_FAILED'):
        // do something when a transfer failed (and no funds were affected)
        break;
    break;
}

Webhook Authentication

Add additional security to your endpoint and prevent spoofing by parsing the X-Webhook-Auth header and verifying its value.

Verify the request was sent by the COINQVEST platform by creating a hash hash('sha256', YOUR_API_SECRET . WEBHOOK_REQUEST_BODY) (where the . symbol represents concatenation) and matching it against the X-Webhook-Auth header value.

Example: Authentication Check (PHP)

$authHeader = $_SERVER['HTTP_X_WEBHOOK_AUTH'];
$payload = file_get_contents("php://input");

if ($authHeader != hash('sha256', $yourApiSecret . $payload)) {
    // this is not a valid webhook
}

Responding to Webhooks

Send 200 OK. Your server must respond with a status code of 200 in the HTTP response after it successfully parsed and persisted 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. If we don't receive an HTTP status code of 200 for longer than that, the webhook expires and stops posting.

PRO Tip

Inspect webhooks sent by COINQVEST along with your HTTP responses in the platform's webhook logs.

This can be extremely useful during implementation phase because it helps to debug issues in the HTTP requests and responses.

WEBHOOK EVENTcheckout-completed

This webhook event is triggered when a customer payment successfully completed, your COINQVEST wallet was credited, and it is safe to ship any goods or services.

WEBHOOK EVENTcheckout-underpaid

This webhook event is triggered when a customer payment was captured but the payment amount was less than expected. In this situation funds have not been credited to your account and you should not ship any goods or services yet.

Unresolved payments are listed in your UI dashboard and contain action options, such as issuing a refund or accepting the underpaid checkout by issuing a custom discount.

If this is a checkout of type HOSTED and you associated a customer with this checkout, our system automatically notifies the customer with instructions on how to complete checkout and pay the remaining difference.

If this is a checkout of type SELF-HOSTED or you did not associate it with a customer, you should notify your user to send another payment covering the difference between sourceAmountRequired and sourceAmountReceived. The payment should be sent to the same deposit address originally associated with this checkout.
