Generating the X-Signature

📘

To securely authenticate API requests, a signature (X-Signature) must be generated and included in the request headers. This signature is a HMAC SHA256 hash of the request data, using a provided secret key.

Steps to Generate the X-Signature:

• Prepare the Data: The data to be sent in the API request (request payload) should be prepared as a string.
• Generate HMAC SHA256 Signature (e.g using crypto-js for Node:
  • Use the HMAC SHA256 algorithm on the request data string.
  • The secret key for HMAC SHA256 is provided (e.g., "sktest$jmrluwtudhbztd@s&lu").
  • The output should be converted to a hexadecimal string.
    Include the Signature in Headers:
    The resulting hexadecimal string is used as the value for the X-Signature header in the API request.
