This how-to guide covers:
  • Setting up your Google Pay integration for use with Mangopay
  • Making payment requests.
For an overview of the data flows, see the Google Pay guide. To integrate Google Pay on your side, see the Google Pay documentation.
Prerequisites

​
1. Configure your Google Pay integration for Mangopay

When making payment requests to the Google Pay API, use the following values:
  • gateway - The payment gateway used: in this case, whenthen.
  • gatewayMerchantId - Your platform’s ClientId provided by Mangopay.
  • allowedAuthMethods - The supported authentication methods: PAN_ONLY, meaning the card is registered in the user’s Google account and requires additional 3DS authentication; CRYPTOGRAM_3DS, meaning the card is enrolled in the customer’s Google Wallet and authentication is handled by Google, with no 3DS redirection and no liability for the platform.
  • allowedCardNetworks - The card networks supported by Mangopay on Google Pay: only VISA and MASTERCARD.

2. Include payment data in the pay-in call

Include the payment data received from Google Pay for the payment as the value for the PaymentData parameter in your request to the Create a Google Pay PayIn endpoint.
