Cancel a session

Request cancellation of current Session work.

POST /api/v1/cloud/sessions/{session_id}/cancel

Requests cancellation of the current turn in a Session. Cancel on a running Session returns HTTP 202 Accepted and the Session transitions through canceling back to idle. Cancel on an idle Session is a safe no-op and returns HTTP 200 OK.

Path parameters

Parameter	Type	Description
session_id	string	Session ID with the sess_ prefix

Headers

Header	Required	Description
Authorization	Yes	Bearer $QODER_PAT

Example request

curl -X POST https://api.qoder.com/api/v1/cloud/sessions/sess_019ef30a4f0275678965d496ab542ef0/cancel \
  -H "Authorization: Bearer $QODER_PAT"

Example response

HTTP 200 OK (no-op) or HTTP 202 Accepted (cancellation applied)

{
  "id": "sess_019ef30a4f0275678965d496ab542ef0",
  "type": "session",
  "status": "canceling"
}

The status field is "canceling" in both cases. After the turn aborts, the Session returns to idle.

Errors

HTTP	Type	Trigger
401	authentication_error	PAT invalid or expired
404	not_found_error	Session does not exist or has been archived

Note: Calling cancel on an already-idle Session is a safe no-op and returns HTTP 200. The response always uses the same lightweight format regardless of whether cancellation was applied (202) or was a no-op (200).

HTTP 404 Not Found

{
  "type": "error",
  "request_id": "cb80235f-76a2-4ff3-9e28-5aa2da12dc14",
  "error": {
    "type": "not_found_error",
    "message": "Session 'sess_does_not_exist_0000000000000000000000000000' was not found."
  }
}
