Overview

This node operation retrieves the changes (diffs) of a specific merge request in a GitLab project using the GitLab API v4. It is useful for developers and DevOps engineers who want to programmatically access the detailed changes introduced by a merge request, such as for code review automation, CI/CD pipelines, or audit logging.

Use Case Examples

  1. Fetch the list of file changes in a merge request to display in a custom dashboard.
  2. Automatically analyze merge request diffs to enforce coding standards or detect sensitive information.
  3. Integrate merge request changes into external tools for enhanced project management.

Output

JSON

  • changes - List of changes (diffs) in the merge request.
  • project_id - ID of the project.
  • merge_request_iid - Internal ID of the merge request.

Troubleshooting

  • Ensure the project ID and merge request IID are correct and accessible with the provided credentials.
