The Four-Step Automation Process:

1. Trigger - Workflow activates via webhook, schedule, or GitLab event
2. Fetch Details - n8n retrieves merge request information via GitLab API
3. Validate Conditions - System checks if approvals, CI pipelines and custom rules are satisfied
4. Execute Merge - If all conditions pass, the system automatically merges the code

Technical Components:

• n8n HTTP Request nodes for GitLab API interaction
• Decision nodes for conditional logic and validation
• Optional notification nodes (Slack, Email, etc.)
• Secure credential storage for GitLab tokens

This low-code solution requires minimal configuration while providing enterprise-grade automation capabilities.
