MoodleInstall

Overview

This node integrates with the Moodle Learning Management System (LMS) to manage courses, users, enrollments, grades, messages, and system information via Moodle's web service API. Specifically, the Course - Delete operation allows you to delete a course by its ID from your Moodle instance.

Typical use cases include:

• Automating course lifecycle management by removing outdated or obsolete courses.
• Cleaning up test or temporary courses in bulk.
• Integrating Moodle course deletion into broader workflows such as user offboarding or curriculum updates.

Example: You have a workflow that triggers when a course is no longer needed, and this node deletes the course from Moodle automatically by specifying its Course ID.

Properties

Output

The node outputs a JSON object indicating the success of the deletion operation. The structure is:

{
  "success": true,
  "message": "Course <courseId> deleted successfully"
}

Where <courseId> is the ID of the deleted course.

No binary data output is produced by this operation.

Dependencies

• Requires an active connection to a Moodle instance with web services enabled.
• Needs an API key credential configured in n8n for authenticating requests to Moodle's REST API.
• The Moodle web service function core_course_delete_courses must be enabled and accessible by the API user.
• The node uses HTTP POST requests to communicate with Moodle's API endpoints.

Troubleshooting

Common Issues

• Permission Denied: The API user may lack permissions to delete courses. Ensure the API token has sufficient rights.
• Invalid Course ID: Providing a non-existent or incorrect course ID will result in failure or no action.
• Web Service Disabled: Moodle web services or the specific function might not be enabled on the server.
• Network Connectivity: Connection issues between n8n and Moodle can cause request failures.

Error Messages and Resolutions

• "Course not found" or empty response: Verify the Course ID is correct and the course exists.
• Authentication errors: Check that the API key credential is valid and has not expired.
• "Function core_course_delete_courses not available": Confirm that the Moodle version supports this function and it is enabled in the external services configuration.
• Unhandled exceptions: Enable "Continue On Fail" in the node settings to handle errors gracefully during batch operations.
