# Get Collection Export Status

GET https://api.prolific.com/api/v1/data-collection/collections/{collection_id}/export/{export_id}

Polls the status of an asynchronous collection export job initiated by `POST /collections/{collection_id}/export`.

Returns the current status of the export:

* **generating** — the export is still being built; continue polling.
* **complete** — the export is ready; a presigned HTTPS download URL is included. URLs are valid for 1 hour and are automatically refreshed if expired.
* **failed** — generation failed (e.g. the archive was deleted from storage). Re-send `POST /collections/{collection_id}/export` to retry.

## Authentication

- `Authorization` header (required) (prefixed with ` Token  `) — The Prolific API uses API token to authenticate requests. You can create an API token directly from your settings. Your API token does not have an expiry date and carries full permission, so be sure to keep them secure. If your token is leaked, delete it and create a new one directly in the app. In your requests add `Authorization` header with the value `Token <your token>`.
