Introduction to the Express integration guide

Amazon Pay provides millions of buyers a secure, trusted, and convenient way to pay for their purchases on your site. To complete their purchase, buyers simply choose a shipping address and payment method stored in their Amazon account.

Express integration offers a Button Generator integration to provide simple copy-and-paste HTML code that you can use to add an Amazon Pay button to your website. For those cases where shipping is required, you can implement a Custom integration that lets you generate the Amazon Pay button on your website and to make API calls.

The table below shows the differences between these features.
