Integration overview
Amazon Pay provides buyers with a secure, trusted, and convenient way to sign in and pay for their purchases on your site by using their Amazon credentials. See browser support for information about the operating systems, browsers, and browser versions that Amazon Pay supports.
Use Saved Wallet to set up a buyer's payment method for future purchases. Setup Intent is an Amazon-hosted experience within Saved Wallet that enables the buyer to save Amazon Pay as a payment method in your mobile app or website without completing a purchase.
Setup Intent is useful for merchants that collect payment details upfront, and for those that need the flexibility to process transactions when the buyer is no longer present:
- A food delivery service that collects payment details before the buyer places their first order
- A ride hailing mobile app that initiates a transaction after the buyer is no longer present
- A car rental company that initiates an additional transaction based on fees incurred after the rental has been returned (e.g., toll road fees)
- An e-commerce retailer that aims to optimize their mobile app checkout experience by not redirecting the buyer outside of the app to complete each purchase
- A merchant that processes transactions in additional channels (e.g., a phone transaction, an offline transaction)
For merchants in European countries impacted by Strong Customer Authentication, the Setup Intent flow presents a challenge to the buyer after they have confirmed their preferred payment method. This is designed to optimize the payment method for future purchases. There are no additional integration steps required.
This guide provides an overview of Saved Wallet and shows you how to launch a custom checkout experience using Setup Intent.
