You first start an export, get an export ID, and then periodically check the status of the export with the Get Campaign Export Status endpoint. You should stop polling as soon as you have a status that is different than “pending”. Multiple exports on the same campaign can be done simultaneously as it is export ID based.

​
How it works

  1. Start the export: Call this endpoint to initiate the export process. You’ll receive an exportId in the response.
  2. Check status: Use the exportId with the Get Campaign Export Status endpoint to periodically check the export status.
  3. Download: Once the status is "done", use the provided URL to download the CSV file.
The export is ID-based rather than campaign-based, allowing multiple simultaneous exports of the same campaign (e.g., one by a user in the application and another by a script).

​
Response

The response includes:
  • exportId: Use this to check the export status
  • status: Will be "pending" initially, then "done" or "error"
  • progress information: Track the export progress

​
Next steps

After starting an export, use the Get Campaign Export Status endpoint to monitor progress and retrieve the download URL when ready.
