  • 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

  • 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
