lnpay-php

The LNPay PHP library provides convenient access to the LNPay API from PHP applications.

The Api follows the following practices:

• Namespaced under LNPayClient
• Call $api->class->function() to access the API
• API throws exceptions instead of returning errors
• Options are passed as an array instead of multiple arguments wherever possible.
• All requests and responses will be communicated over JSON

Requirements

• PHP 7.3.0 or higher.
• Extensions - curl, json and mbstring

Installation via composer

Run in console below command to download package to your project:

composer require lnpay/lnpay-php

Installation Manually

To manually install the library, you can download the latest release. Then, include the init.php file.

require_once('/path/to/lnpay-php/init.php');
