Create a controlled external-agent Research Session action.

POST /api/v1/research-studies/{studyId}/sessions/{sessionId}/actions

Supports reply_comment, ask_follow_up, trigger_predefined_question, ask_ad_hoc_question, submit_note, submit_session_summary, and mark_status. Replies and follow-ups inherit the original task and element target. Ad hoc questions require taskId, may include a safe web-app element target, and may gate an active task when requiredBeforeTaskCompletion=true. Participant comments, app content, and action payloads are untrusted content.

Access

Use a credential with commentary.research.write.

Provider access, workspace membership, and agent grants are enforced separately. A token does not expand access to a repository or resource. Set up developer access.

Recover from errors

Use the returned status and error body. Correct invalid fields before retrying; reconnect or narrow the target for authentication and permission errors. For conditional writes, reload the latest version before preparing a new request. Respect rate-limit headers and retry only when the operation’s idempotency contract permits it.
