Resilient n8n Webhook Ingestion & Gemini Parser Node
Suggested Use: Self-hosted workflow automations connecting document webhooks to databases. Ready to use with Cursor, Claude, ChatGPT. Copy the prompt, adjust any bracketed variables for your project, and refine in your AI tool.
Write a ready-to-use JavaScript Code Node for an n8n workflow that ingests binary files from a document extraction webhook and sends them to Gemini. Requirements: 1. Validate HMAC-SHA256 signature in incoming `x-webhook-signature` header. 2. Extract base64 buffer from binary item without memory leaks. 3. Construct multimodal payload for Gemini with structured JSON schema enforcement. 4. Handle exponential retry on HTTP 429 and 503 errors. 5. Return normalized item containing extracted JSON and execution latency metrics.
Why Use This Prompt?
This prompt guides Cursor and Claude and ChatGPT to generate clean, production-grade n8n, Node.js, Webhook, Gemini code tailored for resilient n8n webhook ingestion & gemini parser node. It establishes strict architectural constraints—including proper error handling, modern framework conventions, and zero conversational filler. Developers can rapidly scaffold robust components, database schemas, or algorithmic utilities while maintaining code quality and maintainability.
