HttpRequest Automate

This workflow is ideal for:

• Developers who need to automate the process of managing merge requests in GitLab.
• Project Managers looking to streamline their code review and merging processes.
• DevOps Engineers seeking to integrate CI/CD pipelines with automated merge request handling.
• Teams that require consistent and timely updates on merge request statuses and comments.
• Automation Enthusiasts interested in utilizing n8n for workflow automation.

This workflow addresses the challenge of managing merge requests efficiently by automating the following tasks:

• Checking for existing merge requests to avoid duplicates.
• Creating new merge requests when none exist, ensuring that development work is not lost.
• Closing existing merge requests that are no longer relevant, keeping the repository clean.
• Adding custom notes to merge requests for better communication among team members.
• Waiting for a specified duration to allow for pipeline completion before merging, ensuring stability in the codebase.

1. Schedule Trigger: The workflow starts based on a defined schedule.
2. API to Check Existing Merge Request: It queries GitLab to check if there are any opened merge requests for a specific source branch.
3. Is Exists: A conditional check determines if any merge requests are found.
4. Create New Merge Request: If no existing merge requests are found, a new merge request is created with the specified source and target branches.
5. Add Custom Notes to Merge Request: Custom comments are added to the newly created merge request for context.
6. 30 Seconds Wait: The workflow pauses for 30 seconds to allow for approvals and pipeline completion.
7. Set Values for Merge: Prepares parameters for the merge request, indicating whether to remove the source branch after merging.
8. Merge When Pipeline Succeeds: Finally, it merges the request once the pipeline succeeds, ensuring that the integration is stable.
