MoodleInstall

Overview

This node integrates with the Moodle Learning Management System (LMS) via its web service API. Specifically, the "Get Enrolled Users" operation under the Course resource retrieves a list of users enrolled in a specified course.

This operation is useful for educational administrators or instructors who want to programmatically access enrollment data for courses. For example, it can be used to:

• Generate reports on course participation.
• Sync enrolled users with other systems.
• Trigger workflows based on course membership changes.

Practical example: An institution could use this node to fetch all students enrolled in a particular course and then send them notifications or update their records in an external CRM system.

Properties

Output

The output is a JSON array where each element represents a user enrolled in the specified course. Each user object contains detailed information as returned by Moodle's core_enrol_get_enrolled_users web service function. Typical fields include user ID, username, full name, email, roles, and other profile details.

No binary data is output by this operation.

Example output snippet (simplified):

[
  {
    "id": 123,
    "username": "student1",
    "fullname": "Student One",
    "email": "student1@example.com",
    "roles": [
      {
        "roleid": 5,
        "name": "Student"
      }
    ],
    ...
  },
  {
    "id": 456,
    "username": "student2",
    "fullname": "Student Two",
    "email": "student2@example.com",
    "roles": [
      {
        "roleid": 5,
        "name": "Student"
      }
    ],
    ...
  }
]

Dependencies

• Requires a valid Moodle API authentication credential configured in n8n to authorize requests.
• The Moodle instance must have web services enabled and the authenticated user must have permission to call core_enrol_get_enrolled_users.
• No additional external dependencies beyond the Moodle API.

Troubleshooting

• Common issues:

  • Invalid or missing Course ID will cause the request to fail.
  • Insufficient permissions for the API user to access enrollment data.
  • Moodle web services not enabled or misconfigured.
  • Network connectivity issues between n8n and the Moodle server.

• Error messages:

  • Errors from Moodle API calls are propagated. For example, if the course does not exist or the user lacks permission, the error message from Moodle will be included.
  • If no users are found, the output will be an empty array; this might indicate no enrollments or permission restrictions.

• Resolution tips:

  • Verify the Course ID is correct and exists in Moodle.
  • Ensure the API user has the necessary capabilities to view enrolled users.
  • Check Moodle web services configuration and enable required functions.
  • Test connectivity and credentials separately using Moodle's API testing tools.
