# Use GooglePay

GooglePay has over 150 million users across 42 global markets using the app each month. The wallet is used on nearly 800.000 websites as a secure payment gateway. Roughly 20% of all mobile purchases are made using this digital payment gateway.

## Supported currencies

GooglePay supports EUR, USD, GBP, CHF, DKK, NOK and SEK transactions.

## Workflow

1. Follow the Google Pay Web documentation (<https://developers.google.com/pay/api/web/overview>) to add a **Google Pay** button to your web page.
2. Use 2Checkout's Google merchant ID when building the `merchantInfo` object.

   ```php
   {
     "merchantInfo": {
       "merchantId": "BCR2DN6T2OAK7HIW"
     }
   }
   ```
3. Set gateway to **verifone** and gatewayMerchantId to your 2Checkout's gateway ID found below when building the tokenizationSpecification object.

   ```php
   {
             "tokenizationSpecification": {
               "type": "PAYMENT_GATEWAY",
               "parameters": {
                 "gateway": "verifone",
                 "gatewayMerchantId": "1ab01f9d-10a6-43fe-9c9e-941798a0813b"
               }
             }
           }
   ```
4. After the shopper authorizes the payment, pass the token from the Google response to Verifone to process the payment. To do this, encode the token to base64 and add it to the `placeOrder` call payload in the `PaymentToken` property.
