Send a message
Post a user message and start (or resume) a run. Returns 202 with a run_id. Poll the run, or subscribe to realtime, for the assistant reply. If a run is awaiting_input, this message is the answer.
Authorizations
Identify accepts a workspace API key (sk_…). Loom accepts either a short-lived session token (direct) or a workspace API key (relay).
Headers
Relay only. Opaque subject id for the acting user. Direct tokens carry sub instead — do not send this header on a session token.
Connection id or name the agent may call. Required in relay when the agent has unpinned customer tools. Direct tokens may carry conn instead.
Path Parameters
Body
User message, or the answer to a pending elicitation.
