Amazon MCF Fulfillment Automation Integration

I manage stores on Shopify, TikTok Shop, and Google Merchant Center and want every paid order on any of those channels to flow straight into Amazon Multi-Channel Fulfillment the moment it is placed—no spreadsheets, no copy-paste, no nightly batch runs. The goal is true “hands-off” fulfillment: an order comes in, Amazon picks, packs, and ships, and the shopper immediately sees tracking inside the channel where they bought.

Core scope
• Capture new orders from Shopify, TikTok, and Google Merchant instantly (webhooks/API)
• Create the matching fulfillment order with Amazon MCF through the Selling Partner API
• Pull back carrier, tracking number, and ship-cost details as soon as Amazon generates them
• Post those details to the original order so the customer and platform both show it as fulfilled
• Handle partials, cancellations, or Amazon out-of-stock responses gracefully

Preferred stack & access
I can provide Amazon SP-API credentials, Shopify private app keys, TikTok Shop API keys, and Google Content API access. Language or framework is up to you—Node, Python, or a lightweight iPaaS glue tool are all fine as long as the flow stays real-time and reliable.

Acceptance criteria
• A live demo where I place a test order on each platform and watch it appear in my Amazon outbound queue within seconds
• Automatic return of tracking that closes the order on the originating platform without manual input
• Clear documentation and source code so I can maintain or extend the workflow later

If you have already connected any one of these channels to Amazon MCF, let me know—speed to launch is more important than building from scratch.
