It is recommended to verify the signature before processing the response to ensure the data has not been tampered with.

While signature verification ensures authenticity, it is advisable to also validate the transaction amount against your order amount as an additional security measure.

Signature Generation

Initialize dataString as an empty string

Remove the 'signature' key from requestBody if available

Define function getArrayValues(requestBody, dataString):
    For each key-value pair in requestBody:
        If value is an array:
            Call getArrayValues(value, dataString)
        Else:
            Append value + '|' to dataString
    Return dataString

Call getArrayValues(requestBody, dataString)
Append '#' to dataString

Generate signature as HMAC-SHA512 hash of dataString using apiSecret as the key

API Secret is generated along with API Token, See Authentication page for more information
