Generate a events webhook signature

The signature is formed from request body and converting it to SHA256 HMAC signed with Client Secret. Signature sent in Authorization header. You can find out the Client Secret in the merchant's account.

Signature validation example in PHP:

<?php

$clientSecret = '123'; // Client Secret

$requestContent = file_get_contents('php://input');
$expectedSignature = hash_hmac('sha256', $requestContent, $clientSecret);
$providedSignature = $_SERVER['HTTP_SIGNATURE'] ?? '';

if (!hash_equals($expectedSignature,$providedSignature)) {
    die('Wrong signature');
}

Parameters sent by the POST method to Webhook Events URL:

event
string
Event name
data
array
Data

Headers sent to Webhook Events URL:

Signature
string
Signature to verify. Use the signature verification method to verify the signature of the request.

OR you can verify the X-SIGN header sent to your server using the algorithm:
md5(clientId + clientSecret) (concatenation).
