Start with ExportFeed — highest vibe code, weakest moat.

Generating static Google Shopping XML and Meta CSV files from store data takes a single afternoon of coding. However, keeping up with Amazon SP-API app approval, Etsy OAuth authentication, dynamic taxonomy mapping, and real-time stock sync across multiple channels introduces ongoing technical overhead.

  • XML and CSV product feed generation for Google Shopping and Facebook Catalog
  • Scheduled background jobs for feed regeneration and file hosting
  • Basic attribute mapping (title, price, description, image URLs)
  • Custom price rules and percentage adjustments per feed
  • Filtering products by category, tag, or inventory status before export

what you lose

  • Direct API submission and error feedback loop with Amazon SP-API and Etsy
  • Automated category mapping against Google and marketplace-specific taxonomies
  • Real-time inventory deduction and order status sync back to the main store
  • Pre-built payload validation against channel-specific listing rules
  • Managed OAuth token refresh and platform developer app registrations
