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.
|Button Generator integration||Custom integration|
|Copy-and-paste integration for fixed price items||✔|
|Adjust the payment amount in a button request (as in a shopping cart)||✔|
|Use the Payment Management Dashboard to manage the capture and authorization of funds||✔||✔|
|Use APIs for authorization and capture of funds||✔|
|Retrieve buyer address for shipping -- helpful for calculating tax and shipping costs||✔|
For more information, see Button Generator integration or Custom integration.
Note If you need address or ZIP code for tax or shipping calculations up front, use One-time payments integration or Recurring payments integration.
