This feature is currently available for the following integrations:

You'd like to see this feature for another integration? Please reach out! We're always happy to discuss extending our coverage. **Note:** This endpoint is asynchronous – it returns a `task_id` immediately and processes the request in the background. Use the corresponding `GET` endpoint to poll for the task status until it reaches `COMPLETED` or `FAILED`. Learn more in our [async endpoints guide](/lms/guides/async-endpoints). This endpoint requires the permission **Upsert courses** to be enabled in [your scope config](/scopes). ### Example Request Body ```json { "items": [ { "origin_id": "course-1", "course": { "type": "EXTERNAL", "title": "Building LMS integrations with Kombo", "description": "Learn how to build and integrate Learning Management System (LMS) integrations with Kombo.
