Additional payment button

You can add an additional payment button for one-time transactions at the end of your checkout flow. The additional button is typically added at the step where the buyer selects their payment method before completing checkout. Unlike the one-time integration, the buyer will not have the opportunity to return to your site to review their order before completing checkout after clicking on the Amazon Pay button.

Key differences from an one-time integration:

  • You can re-use most of the code from your one-time integration. The key differences are:
  • Since the Amazon Pay button is at the end of checkout after buyer has already manually entered their shipping address, you must provide that information in addressDetails for all physical goods transactions. Providing addressDetails for digital goods transactions will result in an error.
