Generate C API HTML docs from Google Drive headers with GPT-4o and Gmail

🚀 Overview

This n8n workflow automatically generates professional API documentation from C header (.h) files using AI.

It scans a Google Drive folder for header files, extracts the source code, sends it to GPT-4o for structured analysis, and generates a beautiful HTML documentation page. The final documentation is uploaded back to Google Drive and a completion email is sent.

This workflow is ideal for embedded systems teams, firmware engineers, and SDK developers who want an automated documentation pipeline.
