Authorizations

​
Authorization
string
header
required

API Key authentication. For all API requests, include your API Key in the Authorization HTTP Header, prefixed with Bearer . Example: Authorization: Bearer {API_KEY}. Strongly recommend storing your API Key on the server-side, not shared or stored on the client-side, to avoid possible API-Key leakage that can lead to serious consequences. Requests with a missing or invalid API key fail with HTTP 401 and error code unauthorized.

Path Parameters

​
task_id
string
required

Task ID, can be obtained from the streaming chunk return of the Run Workflow API.

Body

application/json
​
user
string
required

User identifier, used to attribute the stop request to an end user. It does not need to match the user passed to Run Workflow; the stop applies to the task regardless of user.

Response

Operation successful.

​
result
string

Operation result. Always success.
