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

Description

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.
