Google Pay

Introduction

Loading the Google Pay button via COPYandPAY payment widget requires two actions:

  • Just like any other brand, GOOGLEPAY must be specified as a brand in step 2.
  • Specify your merchant ID in wpwlOptions.googlePay.gatewayMerchantId (Click js tab to see the code example). See the Options section for more information.


Options

Google Pay provides a list of features that can be used via the API Reference.

As with other options, you can modify the Google Pay behavior by using wpwlOptions.googlePay.
