👉 RPC Protocol

The RPC protocol used by Hemi's daemons is WebSocket-based and uses JSON-encoded requests/responses.

The JSON data sent over WebSocket connections are referred to as "messages".

📩 Message Format

An RPC message has the following format:

{
  "header": {
    "command": "command-name",
    "id": "request-id"
  },
  "payload": null
}

Header

The message header contains metadata required for processing the message:

• command: The name of the command being executed.
• id: A string used to uniquely identify each request. Responses will have the same id as the request, making it possible to match requests to responses.

Payload

The payload type depends on the command being called. Please refer to the documentation for more details on the specific API you wish to use.
