My-CoolPay official SDK for PHP

Note

This PHP package let you easily integrate My-CoolPay Payment API to your application or your website. Before you start using this package, it's highly recommended to check resources below depending on your use case.

Table of contents

1. Requirements

This package requires: Required PHP version Extension CURL Extension JSON

2. Installation

2.1. Install Composer package

First of all, install Composer package from your CMD or your Terminal.

$ composer require mycoolpay/php-sdk

2.2. Initialize SDK object

Now you need to initialize the SDK object with your API keys.

<?php

require_once "vendor/autoload.php";

use MyCoolPay\Logging\Logger;
use MyCoolPay\MyCoolPayClient;

define("MCP_PUBLIC_KEY", "<Add your public key here>"); // Your API public key
define("MCP_PRIVATE_KEY", "<Add your private key here>"); // Your API private key

$logger = new Logger('app.log', __DIR__);
$mycoolpay = new MyCoolPayClient(MCP_PUBLIC_KEY, MCP_PRIVATE_KEY, $logger, true);

Recommendations:

  • It is better for you to save your keys outside the source code, in places like environment variables and just load them from source code
  • Logger object is optional, it is used for debug purposes. To know more about My-CoolPay Logger class see My-CoolPay PHP Logger
  • Both Logger and MyCoolPayClient objects don't need to be instantiated every time you need them, just instantiate them once (either at application startup or at first use) then share the instances within whole app with patterns such as Singleton or Dependency Injection

Logger constructor parameters:

See My-CoolPay PHP Logger

MyCoolPayClient constructor parameters:

MyCoolPayClient($public_key, $private_key, $logger = null, $debug = false)

    ]);
    
    $transaction_ref = $response->get("transaction_ref"); // You can store this reference to order in your database
    
    $payment_url = $response->get("payment_url"); // Redirect customer to this url
