V1Response

Every connector call resolves to this envelope.

interface V1Response<T = Record<string, unknown>> {
  header: { version: string; status: 'success' | 'failure';
            request_from?: string; response_from?: string };
  body: {
    command?: string;
    parameter?: T;
    error?: { code: string; message: string };
  };
}

info

The bridge SDK speaks an internal JSON-RPC wire ({ id, result, error }) to the connector; the connector re-wraps it into this V1Response before returning to your app. You only ever see V1Response.
