Auto-post Amazon India affiliate videos to 6 platforms with FLUX, Shotstack and Buffer

Turn any Amazon India product URL into a fully-edited 10-second lifestyle video and auto-publish it to Instagram, Facebook, X (Twitter), LinkedIn, YouTube, and Threads — with platform-optimized captions, hashtags, and FTC-compliant affiliate disclosures.

This end-to-end automation removes every manual step from running an Amazon affiliate content business. Drop product URLs into a Google Sheet, and the workflow handles scraping, image generation, video editing, caption writing, and multi-platform posting on an hourly schedule.

🔧 What this workflow does
──────────────────────────

1. Pulls pending Amazon India product URLs from Google Sheets
2. Scrapes full product data (title, price, discount, rating, features, description, images) via Apify
3. Generates a high-end lifestyle scene prompt using GPT-4o-mini (Art Director persona)
4. Creates a photorealistic lifestyle image with FAL AI's FLUX Kontext Pro — keeping the original product intact
5. Uploads the image to ImgBB for stable hosting
6. Writes platform-native captions for 6 platforms using Gemini 2.5 Flash via OpenRouter:
   • Facebook — engagement-led, Indian family tone
   • Instagram — aspirational with 20-25 hashtags
   • Threads — 180-char punchy hook
   • Pinterest — SEO-optimized long-tail keywords
   • LinkedIn — professional market commentary
   • X — 240-char with raw affiliate link
7. Combines the image + your background audio into a 1080p 1:1 video using Shotstack (with animated text overlays)
8. Posts the final video to all 6 platforms via Buffer's GraphQL API (2 Buffer accounts supported)
9. Updates Google Sheets with per-platform status + Buffer post IDs
10. Sends a full Telegram summary with cost breakdown, video preview, and posting status
