n8n Workflow for Automated ChatGPT Code Review in GitLab Merge Requests

Description

This powerful n8n workflow automates the code review process by leveraging ChatGPT’s AI capabilities within your GitLab environment. When a developer opens or updates a merge request (MR), the workflow is triggered via GitLab’s webhook or API integration. It automatically fetches the code changes from the MR, sends relevant code snippets and context to ChatGPT for analysis, and receives detailed code review feedback. The workflow then posts the review comments directly on the GitLab MR, highlighting potential issues, suggesting improvements, and ensuring your code adheres to best practices. This automation reduces manual review time, accelerates feedback cycles, and enhances code quality across your projects. Ideal for teams seeking continuous integration improvements, this workflow seamlessly blends n8n’s powerful automation with ChatGPT’s AI-driven insights, making your development pipeline smarter and more efficient.
