Fulfillment integrations

Set up your fulfillment apps

Since Amazon fulfills Buy with Prime orders automatically, flowing these orders into the following apps can cause these orders to be double-fulfilled by Amazon and another fulfillment provider

  • Order Management System (OMS) solutions
  • Third-party logistics (3PL) apps
  • Your own warehouse system/other order routing apps

To avoid double fulfillment, it’s best practice to exclude Buy with Prime orders in your OMS/3PL setup using the following identifiers:

  • Fulfillment order location: Buy with Prime
  • Shipping speed name or shipping method: Prime Free Shipping
  • Buy with Prime Location ID

Locate your Buy with Prime Location ID

To find your unique Buy with Prime Location ID, follow these steps:

  1. Open your Shopify Admin.
  2. Go to Settings, and then choose Location.
  3. Copy the URL.
  4. Append ".json” to the end of the URL to create a new one. For example,
  5. Enter the new URL in your browser, and then press enter to see the .json code.

This enables both, MCF and Buy with Prime to support fulfillment on a single SKU. You can find this configuration in Amazon MCF app under Settingsand then Multiple locations.
