Has anyone here tried building an auto-reply system for comments on Instagram, YouTube, Facebook, or Twitter? I’m exploring how to set up a Social Media Auto-Reply workflow using n8n, GPT, and Supabase, with an optional email-based human approval step before replies go live. I'm trying to figure out: 🔧 How do you fetch comments from multiple platforms? 🔧 How do you handle spam, toxicity, or blacklisted keywords? 🔧 What’s the best way to generate smart replies with GPT? 🔧 How can I include a manual approval step via email before posting? 🔧 And how do you manage logs in Google Sheets and store user credentials securely (maybe using Supabase)? Would love to hear how others approached this or any tips you might have! 🙌
