Warning As part of the launch of Android Pay, google deprecated the current web-based Instant Buy API on Dec 15, 2015. To help your consumers speed through checkout on the mobile web or desktop transactions, Google is pleased to provide Chrome Autofill - a product which can automatically populate web-based checkout forms with a credit or debit card associated with a user’s Google account.
What Is Google Wallet Instant Buy?
Google Instant Buy is a merchant-side way of integrating Google Wallet support into a web site or application, enabling customers to checkout in just two clicks using card data stored in Google Wallet. With Google Instant Buy, a user’s sensitive data doesn’t have to be shared with 3rd parties, potentially exposing it to hackers. Instead, like Apple Pay, Google passes a single-use virtual credit card number that the merchant can charge through their existing rails / processing relationship.
How does it work?
Google Wallet Instant Buy allows payments without the need to ask for sensitive personal information, making use of data the user has already stored on Google Wallet. Rather than expose this sensitive data to a merchant, which opens it to being intercepted by cybercriminals, Google Wallet Instant Buy instead sends a virtual card number which can only be used for a one-time authorized transaction. This enables a checkout experience that leads to higher conversions for the merchant and more security for the customer.
