JSON request objects

This reference page describes the Google Pay API request object options to use with your application.

Request objects

IsReadyToPayRequest

This object specifies which payment methods are supported.

Property	Type	Necessity	Description
`apiVersion`	number	Required	Major API version. The value is `2` for this specification.
`apiVersionMinor`	number	Required	Minor API version. The value is `0` for this specification.
`allowedPaymentMethods`	PaymentMethod[ ]	Required	Specifies support for one or more payment methods supported by the Google Pay API. A `tokenizationSpecification` isn't required to determine a viewer's readiness to pay. Provide all required `parameters` properties for each supported `PaymentMethod`.
`existingPaymentMethodRequired`	boolean	Optional	If set to `true`, then the `isReadyToPay()` class method will return `true` if the current viewer is ready to pay with one or more payment methods specified in `allowedPaymentMethods`. Note: In the `TEST` environment, if you set `existingPaymentMethodRequired` to `true` in an `IsReadyToPay()` request, the response always returns `true`.

Example

This example shows you how to support payment cards and Android device tokens from all supported card networks.

{
  "apiVersion": 2,

      }
    }
  ]
}

    "gateway": "example",
    "gatewayMerchantId": "exampleGatewayMerchantId"
  }
}

Use the following table to find the specific "gateway": and "gatewayMerchantId": values for your supported gateway.

Direct

To decrypt a response directly on your servers, set type to DIRECT.

Property	Type	Necessity	Description
`protocolVersion`	string	Required	The version of the encryption/signature protocol expected in the response. Currently, `ECv2` is supported. See Payment data cryptography for more information about available encryption and signature protocols.
`publicKey`	string	Required	Base64-encoded elliptic curve public key. See the Encryption public key format section in our merchant cryptography documentation for more information.

Example


  public static final HashMap<String, String> DIRECT_TOKENIZATION_PARAMETERS =
      new HashMap<String, String>() {{
        put("protocolVersion", "ECv2");
        put("publicKey", DIRECT_TOKENIZATION_PUBLIC_KEY);
      }};Constants.java


  private static JSONObject getDirectTokenizationSpecification()
      throws JSONException, RuntimeException {
    if (Constants.DIRECT_TOKENIZATION_PARAMETERS.isEmpty()
        || Constants.DIRECT_TOKENIZATION_PUBLIC_KEY.isEmpty()
        || Constants.DIRECT_TOKENIZATION_PUBLIC_KEY == null
        || Constants.DIRECT_TOKENIZATION_PUBLIC_KEY == "REPLACE_ME") {
      throw new RuntimeException(
          "Please edit the Constants.java file to add protocol version & public key.");
    }
    JSONObject tokenizationSpecification = new JSONObject();

    tokenizationSpecification.put("type", "DIRECT");
    JSONObject parameters = new JSONObject(Constants.DIRECT_TOKENIZATION_PARAMETERS);
    tokenizationSpecification.put("parameters", parameters);

    return tokenizationSpecification;
  }PaymentsUtil.java

Card Parameters

This object allows you to define the accepted payment card types. Google filters a payer's available payment cards based on your configured options.

Property	Type	Necessity	Description
`allowedAuthMethods`	string[ ]	Required	Fields supported to authenticate a card transaction. `PAN_ONLY`: This authentication method is associated with payment cards stored on file with the user's Google Account. Returned payment data includes personal account number (PAN) with the expiration month and the expiration year. `CRYPTOGRAM_3DS`: This authentication method is associated with cards stored as Android device tokens. Returned payment data includes a 3-D Secure (3DS) cryptogram generated on the device. Important: Ensure that your existing risk checks and controls for payment transactions are also applied to Google Pay transactions. Google Pay validation and fraud checks aren't intended to replace your risk management processes.
`allowedCardNetworks`	string[ ]	Required	One or more card networks that you support, also supported by the Google Pay API. `AMEX` `DISCOVER` `INTERAC` `JCB` `MASTERCARD` `VISA` Note: To offer support for tokenized debit or credit combo cards from Brazil, the `countryCode` in `TransactionInfo` must be `BR`, and both the credit and debit networks need to be specified in the request. The following networks are supported: `VISA` `ELECTRON` `MASTERCARD` `MAESTRO` `ELO` `ELO_DEBIT`
`allowPrepaidCards`	boolean	Optional	Set to `false` if you don't support prepaid cards. Default: The prepaid card class is supported for the card networks specified.
`allowCreditCards`	boolean	Optional (Required for UK Gambling merchants)	Set to `false` if you don't support credit cards. Default: The credit card class is supported for the card networks specified.
`assuranceDetailsRequired`	boolean	Optional	Set to `true` to request `assuranceDetails`. This object provides information about the validation performed on the returned payment data.
`billingAddressRequired`	boolean	Optional	Set to `true` if you require a billing address. A billing address should only be requested if it's required to process the transaction. Additional data requests can increase friction in the checkout process and lead to a lower conversion rate.
`billingAddressParameters`	BillingAddressParameters	Optional	The expected fields returned if `billingAddressRequired` is set to `true`.

Example for CARD

The following is an example of how to support all available card networks and card authentication methods:

{
  "allowedAuthMethods": ["PAN_ONLY", "CRYPTOGRAM_3DS"],
  "allowedCardNetworks": ["AMEX", "DISCOVER", "INTERAC", "JCB", "MASTERCARD", "VISA"],
  "assuranceDetailsRequired": true
}

BillingAddressParameters

This object allows you to set additional fields to be returned for a requested billing address.

Property Type Necessity Description

`format`	string	Optional	Billing address format required to complete the transaction. `MIN`: Name, country code, and postal code (default). `FULL`: Name, street address, locality, region, country code, and postal code.
`phoneNumberRequired`	boolean	Optional	Set to `true` if a phone number is required to process the transaction.
