Important details and next steps

Gather your Amazon account details for Amazon services

You connect Amazon Pay to Shopify Payments so that your customers can use their payment details stored on Amazon to pay for their purchases. You also sign in to Seller Central to verify your Amazon account and inventory held in Amazon fulfillment centers.

Important: The Amazon account that you use to connect Amazon Pay to Shopify Payments must be the same Amazon account that you use to manage your Amazon-fulfilled inventory. You need to use the primary credentials that you used to set up the Amazon account. If you currently use Amazon Pay as a stand-alone payment option, switching to Amazon Pay with Shopify Payments changes how you get paid.

Inventory with Amazon

If you currently use Fulfillment by Amazon for products that you sell on Amazon.com, you need to activate Multi-Channel Fulfillment (MCF) for Buy with Prime to share the inventory that you use to sell on Amazon. If you don’t have inventory with Amazon, you need to activate MCF with Buy with Prime as part of your onboarding (which can take up to 10 business days to complete).

Matching your Shopify and Amazon Catalogs

You can use Shopify SKUs and/or UPCs to manage your catalog on Shopify. On Amazon you can use Amazon SKUs, UPCs, or ASINs. Buy with Prime needs to keep these catalogs in sync to send the correct items to your customers. Buy with Prime asks you to indicate which item is which in a mapping or matching process.

Nothing changes until you choose to offer Prime

Nothing changes on your site until you choose to offer Prime on a per-product basis. After you activate Prime for a product, each time a customer visits the product page, Buy with Prime confirms that you have inventory available, that your account is in good standing, and that the Prime delivery promise to the customer is accurate. Only then does the Buy with Prime button appear on the product page.

Note: When you complete the installation process, go back to the Buy with Prime app for Shopify main menu.

Process overview

After you’ve installed the Buy with Prime app on your Shopify store, you see the onboarding checklist with three steps to set up payments, set up and link your Buy with Prime account, and match your products and turn on Buy with Prime.

Set up payments

After you choose Set up, you’re redirected to Shopify Payment. In Shopify Payment, under Wallets, you set up your Amazon Pay account. Important: Use the primary credentials that you used to set up the Amazon account.

Choose Sign in to activate, and then follow the APay configuration process to provide your sign-in information, privacy policy, and transfer your API key.

For more information, go to Activate payments.

Set up and link your Buy with Prime account

After you’ve set up your APay account, you see the Set up account button. If you’re an existing Buy with Prime merchant, use your existing credentials. If you’re new to Buy with Prime, create a new account.

Review the details about what data is shared with the Buy with Prime app for Shopify, and then choose Authorize to go to the next step.

For more information, go to Set up and link accounts.

Match your products and turn on Buy with Prime

Next, you’re redirected back to the Buy with Prime for Shopify app. In the app, you can match your Shopify catalog with Amazon SKUs. You can then turn on Buy with Prime to set it live on your storefront.

Your latest Shopify catalog is pre-loaded on your SKU mapping page, including product image, product header, and SKU number. (If you have products that are drafted, archived, or don't have Shopify SKUs, they won't show up here.)

When you match your Shopify catalog to your Amazon inventory, you ensure that the right products get shipped to your customers each time. You can either map your products manually, or through a bulk update using Import CSV.

For more information, go to Map your products.
