Payload-Signaturefield on the header used to ensure request integrity and to authenticate yourself since you will use your own API Signature (secret key) to generate and encrypt a hash.
Payload-Signaturefield on the header of the requests will contain the hash generated from hashing the entire JSON Payload:
Payload-Signaturevalue is case sensitive and must be sent in lower case.
jsonPayloadvalue is empty, use an empty string instead.
jsonPayloadshould be converted to UTF-8 before hashing it to prevent
Invalid Signatureerror when sending characters with different encodings.
