Build n8n workflow: Google Form → Claude Vision API → Telegram

Job Details

Description

Summary Hi! Looking for an n8n specialist to build one workflow. I have a full technical specification already written — architecture diagram, node-by-node config, the JavaScript for every Code node, and the AI prompt. You would be implementing an existing spec rather than designing from scratch. WORKFLOW OVERVIEW (~13 nodes) 1. Google Sheets Trigger — new row from a Google Form submission 2. Google Drive — download the submitted photo 3. Code — convert to base64, carry over form fields 4. HTTP Request — Anthropic Claude Vision API (image + prompt, structured JSON response) 5. Code — parse and clean the JSON response, with error handling 6. IF — check photo quality flag; false branch sends a "please resend a better photo" message and ends 7. Google Sheets — read a recommendations database 8. Code — map detected items to matching recommendations 9. Code — build the final formatted message 10. Telegram — send to me for review (human-in-the-loop) 11. Wait — resume on webhook, triggered by inline approve/reject buttons 12. Telegram — send the approved message to the end user 13. Google Sheets — append a log row TECHNICAL CONSTRAINTS - Hosted on n8n.cloud, so no community nodes — Claude must be called via HTTP Request - Google OAuth2 credentials for Sheets and Drive - Output messages are in Spanish, with Markdown parse mode - Volume is low: 10–30 executions per week - Scope of THIS quote is Telegram only. WhatsApp Business API is a possible later phase — quote it separately if you want, but don't bundle it in WHAT I NEED FROM YOU - A fixed price, not hourly - Delivery timeline - Confirmation that you'll test end-to-end with real sample photos before handover, including the approve/reject branch and the failed-parse branch - A short handover doc or Loom so I can maintain it myself - Number of revisions included - Whether you can verify the current Anthropic model string and API version at build time (the spec was written a while ago and that detail may have changed) Happy to send the full spec document so you can quote accurately. Thanks!
