Delete submission

Returns the current status of a clipping submission. Poll this endpoint until `status` is `completed` or `failed`. We recommend polling every **5–10 seconds**. When `status` is `queued`, use `queue_position` and `estimated_time` to give feedback to your users. A submission can sit at `downloading` because the SOURCE is not fully published yet — a scheduled premiere, a livestream still on air, or a recording the platform is still processing. In that case `waiting_reason` is set (and `waiting_until` carries the announced start time, when the platform provides one). This is not an error and the submission is not stuck: it resumes on its own once the source becomes available. Surface it to your users instead of a generic "downloading", and offer them the option to cancel — `DELETE /v1/clips/{videoId}/submissions/{submissionId}` refunds the credits while `waiting_reason` is set.
