Merchant Fulfillment API

An application program interface (API) is a tool that 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.

Terms and conditions

Before you can use Buy Shipping, you must review and accept Amazon's terms and conditions and the terms and conditions of carriers that you want to buy shipping from.

To review and accept the terms and conditions:

1. In your seller account, go to Manage Shipping Services.
2. Read Amazon's terms and conditions for this service and the terms and conditions of each carrier, and click the I agree check boxes to accept them.
   Important: If you don't agree to the terms and conditions for a particular carrier, its shipping services won't be available to you.
3. Click Submit.

Developers can learn more about building applications at Amazon MWS.
