    }
  }
}

User-facing message to describe the payment method that funds this transaction.
info object Yes The value of this property depends on the payment method type returned. For CARD, see CardInfo.

This example response shows how a CARD payment method that's selected in the Google Pay payment sheet generates a payment method token for the example gateway.

  "info": {
    "cardNetwork": "VISA",
    "cardDetails": "1234"
  },
  "tokenizationData": {
    "type": "PAYMENT_GATEWAY",
    "token": "examplePaymentMethodToken"
  }
}

CardInfo

This object provides information about the selected payment card.

Property Type Always exists Description
cardDetails string Yes The details about the card. This value is commonly the last four digits of the selected payment account number.
assuranceDetails AssuranceDetailsSpecifications Yes This object provides information about the validation performed on the returned payment data if assuranceDetailsRequired is set to true in the CardParameters.
cardNetwork string Yes

The payment card network of the selected payment. Returned values match the format of allowedCardNetworks in CardParameters.

This card network value should not be displayed to the buyer. It's used when the details of a buyer's card are needed. For example, if customer support needs this value to identify the card a buyer used for their transaction. For a user-visible description, use the description property of PaymentMethodData instead.
billingAddress Address No The billing address associated with the provided payment method, if billingAddressRequired is set to true in CardParameters.

Example

This example shows a card on the Visa network.

{
  "cardNetwork": "VISA",
  "cardDetails": "1234",
  "assuranceDetails": {
    "cardHolderAuthenticated": false,
    "accountVerified": true
  }
}

AssuranceDetailsSpecifications

This object provides information about what validation has been performed on the returned payment credentials so that appropriate instrument risk checks can be applied.

Name Type Description
accountVerified boolean If true, indicates that Cardholder possession validation has been performed on returned payment credential.
cardHolderAuthenticated boolean

If true, indicates that identification and verifications (ID&V) was performed on the returned payment credential.

If false, the same risk-based authentication can be performed as you would for card transactions. This risk-based authentication can include, but not limited to, step-up with 3D Secure protocol if applicable.

You can receive and process the response Object even if you don’t use the assuranceDetails field. To receive this object, include assuranceDetailsRequired: true in the Request object's CardParameters.
