Important: You must be an Amazon MWS developer in order to send a Merchant Fulfillment request.
An application programming interface (API) is a tool which developers can use to build software applications.
Developers can use the Merchant Fulfillment API to build applications that let sellers purchase shipping using Amazon's Buy Shipping.
If you want to buy shipping from your seller account, see Buy shipping through Seller Central.
With the Merchant Fulfillment API, you can:
-
Access Buy Shipping through the Amazon Marketplace Web Service (Amazon MWS).
-
Manage your shipping with a shipping integrator that has adopted the Merchant Fulfillment API.
-
Purchase shipping services directly through the Merchant Fulfillment API.
Note: Refer to the
MWS documentation for how to fulfill orders for each marketplace via the MWS API.
