# Configuring Google Pay

If you're using [DigitalRiver.js with Elements](https://docs.digitalriver.com/digital-river-api/payments/payment-integrations-1/digitalriver.js), you can create a [Google Pay](https://docs.digitalriver.com/digital-river-api/payments/supported-payment-methods/google-pay) payment method for your app or website in two easy steps:

* [Step 1: Create a Google Pay source using DigitalRiver.js](#step-1-create-a-google-pay-source-using-digital-river-js)
* [Step 2: Use the authorized source](#step-2-use-the-authorized-source)

## Step 1: Create a Google Pay source using Digital River.js

To create a Google Pay payment source, follow the instructions for [creating a Google Pay element](https://docs.digitalriver.com/digital-river-api/developer-resources/reference/elements/google-pay-elements#creating-a-google-pay-element).

### Create a Google Pay element

After setting up your library per the [DigitalRiver.js reference guide](https://docs.digitalriver.com/digital-river-api/payments/payment-integrations-1/digitalriver.js/quick-start), create a Google Pay element with any customizations you would like to apply.

{% code overflow="wrap" %}

```javascript
var paymentRequestData = digitalriver.paymentRequest({
        country: "US",
        currency: "USD",
        total: {
            label: "Order Total",
            amount: 100
        },
        displayItems: lineItems,
        shippingOptions: shippingOptions,
        style: {
            buttonType: "plain",
            buttonColor: "dark",
            buttonLanguage: "en"
        },
        "sessionId": "9f180964-9da4-43ac-b8e0-ae54d832b03c"
    });


var googlepay = digitalriver.createElement('googlepay', paymentRequestData);
```

{% endcode %}

### Configure the Google Pay element to handle events

The Google Pay element will surface events, which will give you more information to facilitate what is happening within the Google Pay experience.

These events include:

| Event                                                                                                                                                       | Triggered When                                                                                                                                            |
| ----------------------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------- |
| [ready](https://docs.digitalriver.com/digital-river-api/developer-resources/reference/elements/google-pay-elements#ready)                                   | The created element is loaded and ready to accept an update request.                                                                                      |
| [click](https://docs.digitalriver.com/digital-river-api/developer-resources/reference/elements/google-pay-elements#click)                                   | A shopper clicked the element's button.                                                                                                                   |
| [cancel](https://docs.digitalriver.com/digital-river-api/developer-resources/reference/elements/google-pay-elements#cancel)                                 | The customer has canceled the experience.                                                                                                                 |
| [shippingoptionchange](https://docs.digitalriver.com/digital-river-api/developer-resources/reference/elements/google-pay-elements#shipping-option-change)   | The customer has chosen a different shipping option than was previously selected. You should use this data to re-price your order totals (if applicable). |
| [shippingaddresschange](https://docs.digitalriver.com/digital-river-api/developer-resources/reference/elements/google-pay-elements#shipping-address-change) | The customer has chosen a different address than was previously selected. You should use this data to re-price your order totals (if applicable).         |
| [source](https://docs.digitalriver.com/digital-river-api/developer-resources/reference/elements/google-pay-elements#source)                                 | The customer has authorized the payment and a source, and DigitalRiver.js returned associated data.                                                       |

{% hint style="info" %}
**Note**: To use Google Pay, you must listen to, at minimum, the Source event.
{% endhint %}

{% code overflow="wrap" %}

```javascript
googlepay.on('source', function(event) {
    var source = result.source;

    //pass the source to your back end for further processing. 


    //once verified that the source is created successfully, complete the Google Pay session by answering with a success message
    event.complete('success');
});


googlepay.on('shippingaddresschange', function(event) {
    var shippingAddress = event.shippingAddress;


    //create a Payment Request Details Update Object
    var newDetails = createPaymentRequestDetailsUpdateObject();

    event.updateWith(newDetails);
});
```

{% endcode %}

The Shipping Address Changed and Shipping Method Changed events require a response with updated details to present to the Shopper. This system expects the response to be a [Payment Request Details Update object](https://docs.digitalriver.com/digital-river-api/developer-resources/reference/digital-river-payment-objects#payment-request-details-update-object).

### Place the elements on the page

The following example shows how to place the elements on the page. For more information on placing elements on a page, see Google Pay example.

{% code overflow="wrap" %}

```javascript
if (googlepay.canMakePayment()) {
    googlepay.mount("googlepay-element");
    document.getElementById('googlepay-element').style.display = 'block';
}
```

{% endcode %}

### Receive the source event and use the source

{% code overflow="wrap" %}

```javascript
googlepay.on('source', function(event) {
    var source = result.source;

    //pass the source to your back end for further processing. 


    //once verified that the source is created successfully, complete the Google Pay session by answering with a success message
    event.complete('success');
});
```

{% endcode %}

### Google Pay example

The source event will surface a Source plus other details provided from Google Pay, such as the shopper's billing address, shipping address, and contact information, in the response.

{% hint style="info" %}
The `address` object must contain [postal code](https://docs.digitalriver.com/digital-river-api/integration-options/checkouts/creating-checkouts/providing-address-information#postal-code-validations) and [state/province](https://docs.digitalriver.com/digital-river-api/integration-options/checkouts/creating-checkouts/providing-address-information#states-and-province-validations) data that [adheres to a standardized format](https://docs.digitalriver.com/digital-river-api/integration-options/checkouts/creating-checkouts/providing-address-information#postal-code-and-state-province-validations).

{% endcode %}

## Step 2: Use the authorized source

Once authorized, you can use the source by [attaching it to a checkout](https://docs.digitalriver.com/digital-river-api/payment-sources/using-the-source-identifier#attaching-sources-to-checkouts) or a [customer ](https://docs.digitalriver.com/digital-river-api/payment-sources/using-the-source-identifier#attaching-sources-to-customers)for multiple uses.

### Option 1. Attach the source to a cart

{% tabs %}
{% tab title="POST /checkouts/{id}" %}
{% code overflow="wrap" %}

```javascript
{
  "customerId": "5774321008",
  "sourceId": "src_a78cfeae-f7ae-4719-8e1c-d05ec04e4d37"
}
```

{% endcode %}
{% endtab %}
{% endtabs %}

### Option 2. Attach the source to a customer

{% tabs %}
{% tab title="POST /customers/{id}/sources/{sourcesId}" %}
{% code overflow="wrap" %}

```javascript
{
  "id": "5774321008",
  "sourceId": "src_a78cfeae-f7ae-4719-8e1c-d05ec04e4d37"
}
```

{% endcode %}
{% endtab %}
{% endtabs %}

The following example shows how to place a Google Pay element on your page. Use this in conjunction with the [DigitalRiver.js reference guide](https://docs.digitalriver.com/digital-river-api/payments/payment-integrations-1/digitalriver.js/quick-start) to build your solution.
