Moodle

Overview

This node integrates with the Moodle Learning Management System (LMS) via its web service API, enabling automation of various Moodle operations. Specifically for the User - Delete operation, it allows you to delete a user from the Moodle system by specifying their user ID.

Common scenarios where this node is beneficial include:

• Automating user lifecycle management in Moodle, such as removing users who have left an organization.
• Integrating Moodle user management with external HR or CRM systems to keep user data synchronized.
• Cleaning up test or temporary user accounts programmatically.

Practical example:

• Automatically delete a user from Moodle when they are removed from your company’s directory system by passing their user ID to this node.

Properties

Output

The output JSON object after deleting a user contains:

• success (boolean): Indicates whether the deletion was successful (true).
• message (string): A confirmation message stating that the user with the specified ID was deleted successfully.

Example output JSON:

{
  "success": true,
  "message": "User 123 deleted successfully"
}

No binary data is produced by this operation.

Dependencies

• Requires a valid connection to a Moodle instance with enabled web services.
• Needs an API authentication credential configured in n8n to authorize requests to Moodle's web service API.
• The Moodle web service must have the function to delete users enabled and the authenticated user must have permission to perform deletions.

Troubleshooting

Common Issues

• Permission Denied: If the API user lacks permissions to delete users, the request will fail. Ensure the API token has sufficient rights.
• Invalid User ID: Providing a non-existent or invalid user ID will result in an error or no action.
• Web Service Disabled: Moodle web services or the specific delete user function might not be enabled on the server.
• Network/Authentication Errors: Connectivity issues or incorrect API credentials will prevent successful execution.

Error Messages and Resolutions

• "User not found" or similar: Verify the user ID exists in Moodle.
• "Access denied" or "Permission error": Check the API user's permissions and roles.
• "Invalid web service function": Confirm that the Moodle instance supports the delete user web service function and it is enabled.
• Network timeouts or authentication failures: Validate API credentials and network connectivity.
