Export Project

Triggers the rendering/export process for a completed project. This starts the video generation process asynchronously with customizable output parameters.

Before exporting a project, ensure:

  • Project is not uploading: Cannot be in “uploading” status
  • Project ownership: Must belong to the authenticated user

​
Webhook Notifications

If you provide a webhookUrl, the system will send a POST request to your URL when export completes, including export details and download URL in the notification.

​
Export Status Tracking

After triggering an export:
  1. Monitor Progress: Call GET /v1/projects/{id} to check export progress
  2. Check Download URL: The downloadUrl and directUrl fields will be populated once rendering is complete
curl -X POST "https://api.submagic.co/v1/projects/550e8400-e29b-41d4-a716-446655440000/export" \
  -H "x-api-key: sk-your-api-key-here" \
  -H "Content-Type: application/json"

{
  "message": "Export started successfully",
  "projectId": "550e8400-e29b-41d4-a716-446655440000",
  "status": "exporting"
}
Tip: After triggering an export, use the Get Project endpoint to monitor the export progress. The downloadUrl and directUrl fields will be populated once the rendering is complete.
Important: The export process is asynchronous. The API will return immediately after starting the export, but the actual video rendering happens in the background. Use webhooks or polling to track completion status.
