After you submit a job and receive an operation id, call GET /operation/v1/{operationId}/status to find out where things stand.
The status field will be one of:
- pending — the job is queued but hasn't started processing yet.
- processing — the job is running; a progress value may also be returned.
- completed — the job finished successfully and the result is ready to download.
- failed — the job could not be completed; an error object with a message is included.
Note: Poll at a reasonable interval (for example every 1–2 seconds) rather than continuously, especially for larger files or batch jobs, to avoid unnecessary load on your integration and on the API.
