Getting Started
Message Signing
The signature of a message is a string that is generated by signing the message with your Secret Key. The signature is used to verify that the message is sent by you.
Signature Generation
The signature is generated from your request body and your Secret Key. The following shows the steps to generate the signature:
- Concatenate the request body and your Secret Key.
- Calculate the MD5 hash of the concatenated string.
Sign: MD5(RequestBody + SecretKey)
