Generating A Signature:

To create a signature, hash the JSON body of the request using your secret key with the SHA-256 algorithm. Make sure the JSON body is in a consistent string format before hashing.

Below are examples of how a signature hash can be generated correctly.

<?php

$data = [
    "apiKey" => "example_public_key",
    "timestamp" => "2025-05-16T09:38:25.000Z"
];

// Convert to JSON string
$json_data = json_encode($data);

echo "Data being signed: <br><pre>" . $json_data . PHP_EOL . "</pre><br>";

// Use the correct secret key, replace with your actual secret key
$secret_key = "example_secret_key";

// Generate signature
$signature = base64_encode(hash_hmac('sha256', $json_data, $secret_key, TRUE));

echo "<br>Generated signature: <br>" . PHP_EOL . $signature . PHP_EOL . "<br>";

// Add signature to the original data array (not the JSON string)
$data['signature'] = $signature;

echo "<br>Data with signature: <br><pre>" . PHP_EOL . json_encode($data) . "</pre>" . PHP_EOL;

Postman Pre-Request Script:

const publicKey = "YOUR KEY HERE";
const secretKey = "YOUR SECRET HERE";

function getISOTimestamp() {
   const now = new Date();
   const pad = (n) => String(n).padStart(2, '0');
   return `${now.getUTCFullYear()}-${pad(now.getUTCMonth()+1)}-${pad(now.getUTCDate())}T${pad(now.getUTCHours())}:${pad(now.getUTCMinutes())}:${pad(now.getUTCSeconds())}+00:00`;
}

const timestamp = getISOTimestamp();

// Get the request body and parse it
const requestBody = JSON.parse(pm.request.body.raw);

// Add/update required fields
requestBody.apiKey = publicKey;
requestBody.timestamp = timestamp;

// Remove signature field if it exists (before signing)
delete requestBody.signature;

// Generate signature from the body
const jsonData = JSON.stringify(requestBody);
const signature = CryptoJS.enc.Base64.stringify(
   CryptoJS.HmacSHA256(jsonData, secretKey)
);

// Add signature back to the body
requestBody.signature = signature;

// Update the request body
pm.request.body.raw = JSON.stringify(requestBody);

// Set environment variables for reference
pm.environment.set("apiKey", publicKey);
pm.environment.set("timestamp", timestamp);
pm.environment.set("signature", signature);

Example postman body (Used with the above):

{
  "apiKey": "{{apiKey}}",
  "timestamp": "{{timestamp}}",
  "order_id": "cebf8171-f538-4e43-856a-2d3b7cbed8cf",
  "signature": "{{signature}}"
}
