# Google Pay

> AVAILABILITY
Google Pay is currently available with our latest Android and JavaScript SDKs.

Google Pay provides a purchasing experience both in app and on the web for customers with supported Android devices. It allows customers to pay with cards and PayPal accounts stored in their Google account, in addition to those stored in Google Pay.

For more details on compatibility and availability, see our [Google Pay support article](https://developer.paypal.com/braintree/articles/guides/payment-methods/google-pay).

## Getting started
If you don't already accept Google Pay, you'll need to follow these steps to add a Google Pay to your existing Braintree integration:

* Configure Google Pay
* Integrate on your servers

### Configure Google Pay
In order to accept payments via Google Pay in sandbox or production, you will need to enable it in the Control Panel. To do so:

1. Log into either your [sandbox Control Panel](https://sandbox.braintreegateway.com/login) or [your production Control Panel](https://www.braintreegateway.com/login)
1. Click on the gear icon in the top right corner
1. Click Processing from the drop-down menu
1. Scroll to the Payment Methods section
1. Next to Google Pay, click the toggle to turn it on

If you already have Google Pay activated in your Control Panel, but need to get this payment method enabled for a particular merchant account, [contact us](https://developer.paypal.com/braintree/help?issue=acceptPaymentTypes).

In production, you'll also need to work with Google to go live.

#### PayPal via Google Pay
To accept PayPal payments via Google Pay, make sure you have enabled both PayPal and Google Pay in the Control Panel.

### Integrate on your servers
#### Creating transactions
For the purpose of making transactions, an Google Pay card is treated just like other credit cards with a few noted differences.

Using [chargePaymentMethod](https://graphql.braintreepayments.com/reference/#Mutation--chargePaymentMethod) mutation and supply just an amount and paymentMethodId (which is called payment method nonce on the client-side) you can create a Google Pay card transaction.

*Request body*

mutation ChargePaymentMethod($input: ChargePaymentMethodInput!) {
  chargePaymentMethod(input: $input) {
    transaction {
      id
      createdAt
      status
      amount {
        value
        currencyCode
      }
      merchantAccountId
      paymentMethodSnapshot {
        ... on CreditCardDetails {
          brand
          brandCode
          last4
          expirationMonth
          expirationYear
          cardholderName
          origin {
            type
            details {
	      ... on GooglePayOriginDetails {
                googleTransactionId
                bin
              }
            }
          }
        }
      }
      processorResponse {
        legacyCode
        message
        avsPostalCodeResponse
        avsStreetAddressResponse
        cvvResponse
      }
    }
  }
}

    }
}

Notice the *origin* bits in the response. The *type* clearly spells out that it's a Google Pay transaction. You should collect and pass device data under *riskData* of inputs in order to increase likelihood of a successful authorization.

#### Vaulting Google Pay
Google Pay cards can only be saved to your Vault for specific use cases; see the [support article for details](https://developer.paypal.com/braintree/articles/guides/payment-methods/google-pay#recurring-billing-and-vaulting).

Vaulting of PayPal accounts from Google Pay is currently not supported. This means the options passed in *vaultPaymentMethodAfterTransacting* while using [chargePaymentMethod](https://graphql.braintreepayments.com/reference/#Mutation--chargePaymentMethod) mutation are not supported when creating a transaction.

If your use case is supported, you can store a customer's Google Pay card in your Vault using one of the following mutations:

* [vaultPaymentMethod](https://graphql.braintreepayments.com/reference/#Mutation--vaultPaymentMethod) mutation
* [createCustomer](https://graphql.braintreepayments.com/reference/#Mutation--createCustomer) mutation
* [updateCustomer](https://graphql.braintreepayments.com/reference/#Mutation--updateCustomer) mutation
* [chargePaymentMethod](https://graphql.braintreepayments.com/reference/#Mutation--chargePaymentMethod) mutation
