How to accept Litecoin (LTC) payments with PHP

Over the last decade, the way we can receive value over the internet has dramatically shifted from traditional payments to programmable money. Cryptocurrencies like Litecoin have emerged and can be embedded into online shops or e-commerce sites to receive customer payments.

In its simplest form, all that is needed to receive Litecoin (LTC) payments in PHP is to display a Litecoin address to the customer. Albeit outside of the scope of this document, it is easy to create a Litecoin address programmatically and obtain control of the private key. This is a good starting point if you are a PHP developer and wish to create your own Litecoin address.

This simple type of Litecoin payment integration is suitable for anonymous donations, but requires a lot of additional overhead to make it play well with accounting systems, compliance, and regulatory requirements. Connecting them with customer information and monitoring the Litecoin Network to detect the correct payment transaction and mark the sale as completed, introduce plenty of additional complexity in PHP.

Fortunately, COINQVEST provides a suite of APIs and a convenient PHP software development kit (SDK) for online merchants and e-commerce site who wish to accept Litecoin payments. Using COINQVEST, it is no longer necessary to continuously monitor various blockchains for payment transactions. COINQVEST creates cryptocurrency payment transactions on your behalf and automatically notifies you once the payment has been settled.

    'charge' => array(
        'currency' => 'USD', // specifies the billing currency
        'lineItems' => array( // a list of line items included in this charge
                'description' => 'T-Shirt',
                'netAmount' => 10, // denominated in the currency specified above
                'quantity' => 1
        'discountItems' => array( // an optional list of discounts
                'description' => 'Loyalty Discount',
                'netAmount' => '0.5'
        'shippingCostItems' => array( // any shipping costs?
                'description' => 'Shipping and Handling',
                'netAmount' => '3.99',
                'taxable' => false // sometimes shipping costs are taxable
        'taxItems' => array( // any taxes?
                'name' => 'CA Sales Tax',
                'percent' => '0.0825' // 8.25% CA sales tax
        'customerId' => $customerId, // associates this charge with a customer
    'settlementCurrency' => 'EUR' // specifies in which currency you want to settle
