API Documentation

Complete integration guide for PAYOPIE Payment Gateway API

Your API Credentials

Use these credentials to authenticate with the PAYOPIE API.

App ID
YD5r73
API Key
kimpay3WwEJAxa
Payment Mode
Auto (Sandbox/Live)
Important: Keep your API credentials secure. Do not share them in client-side code or public repositories.

Signature Generation

All API requests must include a signature for authentication. The signature is generated using MD5 hash.

Steps to Generate Signature:

  1. Sort all parameters alphabetically by key
  2. Create a string: key1=value1&key2=value2&key=YOUR_API_KEY
  3. Generate MD5 hash and convert to uppercase

PHP Example:

signature.php 
// Example in PHP:
$data = [
    'app_id' => 'YD5r73',
    'amount' => 100,
    'order_sn' => 'ORDER123'
];

// Sort parameters alphabetically
ksort($data);

// Create query string
$string = '';
foreach ($data as $k => $v) {
    $string .= $k . '=' . $v . '&';
}
$string .= 'key=YOUR_API_KEY';

// Generate signature
$signature = strtoupper(md5($string));

// Example Signature: 05BCE8C7DCB30EC2BE07FB159DD86C6A

  • Your server should respond with HTTP 200 OK within 5 seconds
  • We'll retry failed callbacks up to 3 times
  • Callback URL can be set globally in merchant settings or per request
