hyperledger - Hyperledger rest api ID field value

Question

Hyperledger rest API, what's the use of the "ID" field of the payload? Is it a correlation field to keep track of the rest call?

"id":60

{"jsonrpc":"2.0","result":{"status":"OK","message":"100"},"id":60}

Answer 1

Yes you are right id field is a correlation field to keep track of the rest call.

As described here, http://www.jsonrpc.org/specification#parameter_structures

id

This member is REQUIRED.

It MUST be the same as the value of the id member in the Request Object.

If there was an error in detecting the id in the Request object (e.g. Parse error/Invalid Request), it MUST be Null.
