The "Bad Signature Header" error may occur due to the following reasons:
The signature is generated from a data array without first converting it into a string.
Solution: Ensure the signature is sent as a string.A code error, such as extra characters or spaces.
Solution: Check your code for errors and ensure no extra characters are present.The signature is created from the entire data array, including the public key and headers, instead of using only the secret key.
Solution: The signature should be generated exclusively based on the secret key.The public key is sent in the wrong parameter.
Solution: In some programming languages (e.g., PHP), the public key may mistakenly be included in paramsArray instead of the request body.
