What is the "id": 1 in the body for?

Question

Hi!

I'm exploring Multichain API.

C:\Multichain>multichain-cli chain1 liststreams
{"method":"liststreams","params":[],"id":1,"chain_name":"chain1"}

- Anybody can explain to me what the "id": 1 in the body is for?

Thank you!

Multichain uses RPC 1.0 calls.

The RPC 1.0 protocol request specifies to send an ID. This is the id you are referring to. It can be whatever integer you want. 

Quote from JSON-RPC:

• id - The request id. This can be of any type. It is used to match the response with the request that it is replying to.
