Cancel video

Cancel an in-progress video generation task. A task can be cancelled only while it is still running — once it reaches a terminal state (completed, failed, cancelled, expired), it can no longer be cancelled.


DELETE https://api.ofox.ai/v1/videos/{id}

Cancellation depends on the upstream provider. Ofox accepts a cancel request only when the upstream provider genuinely supports interruption — it never reports a fake success by marking the task cancelled locally while the upstream keeps generating. Providers that cannot interrupt a running job return 400 cancel_not_supported.

Request

Terminal


curl -X DELETE https://api.ofox.ai/v1/videos/9bcf3c60-7db2-4e1a-a1b2-c3d4e5f60718 \
  -H "Authorization: Bearer $OFOX_API_KEY"

Response

A successful cancel returns 204 No Content with an empty body.


HTTP/1.1 204 No Content

After a successful cancel the task’s status becomes cancelled. Polling GET /v1/videos/{id} then returns the cancelled terminal state, and if you registered a callback_url you also receive a video.generation.cancelled webhook.

Cancellation behavior

Whether a cancel is accepted depends on the task’s current state and on whether the upstream provider supports interruption:

Task state	Behavior	Response
`pending` (not yet submitted upstream)	Cancelled locally	`204`
`queued` / `in_progress`, provider supports interruption	Upstream cancel is called, then the task is marked cancelled on success	`204`
`queued` / `in_progress`, provider does not support interruption	Rejected (no fake success)	`400 cancel_not_supported`
Already in a terminal state	Rejected	`400 cancel_failed`
Not found / not owned by your key	Unified response (prevents existence disclosure)	`404 not_found`

A task that does not exist and a task owned by a different API key return the same 404 not_found, so the response never reveals whether a given task id exists.

Errors

HTTP	code	Meaning
`400`	`cancel_not_supported`	The upstream provider does not support interrupting a running job
`400`	`cancel_failed`	The task is already in a terminal state and cannot be cancelled
`404`	`not_found`	The task does not exist, or it is not owned by your API key

Errors use the shared error object:


{
  "error": {
    "code": "cancel_not_supported",
    "message": "The upstream provider for this task does not support cancellation."
  }
}

See the full error reference for every code. DELETE is not subject to the polling rate limit that applies to GET — see Get video status for details.
