Managing Google Pay Authentication Types

Additional controls are available for Google Pay on
Unified Checkout
. When you enable Google Pay on
Unified Checkout
, you can specify optional parameters that define the types of card authentication you receive from Google Pay.
To manage the types of credentials that Google Pay sends, use this expanded payment type object within the
allowedPaymentTypes
 section of the sessions request: 
{
  "type": "GOOGLEPAY",
  "options": { "allowedAuthMethods": "<authentication type>"
  }
}
The expanded payment type object has these parameters:
  • type
    : Defines the type of payment option.
  • options
    : Contains specific payment types parameters.
    For Google Pay, use the new data element
    allowedAuthMethods
     within the
    options
     section of the payment types object to specify the authentication type you will receive from Google Pay. Possible values:
    • PAN_ONLY
      : Google returns primary account number (PAN) values
    • CRYPTOGRAM_3DS
      : Google returns fully authenticated network token values.
    By default, Google sends both authentication types.
