# Configuring Alipay (domestic)

If you're using[ DigitalRiver.js with Elements](/commerce-api/payments/payments-solutions/digitalriver.js.md), you can create an Alipay (domestic) payment method for your app or website in four easy steps:

* [Step 1: Alipay (domestic) Source Details object](#step-1-build-an-alipay-domestic-source-request-object)
* [Step 2: Create the Alipay (domestic) source using DigitalRiver.js](#step-2-create-the-alipay-domestic-source-using-digitalriver.js)
* [Step 3: Authorize an Alipay (domestic) source](#step-3-authorize-an-alipay-domestic-source)
* [Step 4: Use the Authorized source](/commerce-api/payments/payments-solutions/digitalriver.js/payment-methods/alipay.md#step-4-use-the-authorized-source)

## Step 1: Build an Alipay (domestic) source request object

Build an Alipay (domestic) Source Request object. The Alipay Source Request object requires the following fields.

| Field     | Value                                                                                                                                |
| --------- | ------------------------------------------------------------------------------------------------------------------------------------ |
| type      | alipay                                                                                                                               |
| sessionId | The payment session identifier.                                                                                                      |
| owner     | An [Owner object](/commerce-api/payments/payments-solutions/digitalriver.js/payment-methods/common-payment-objects.md#owner-object). |
| alipay    | An [Alipay (domestic) Source Details](#alipay-domestic-source-details-object) object that includes the details of the transaction.   |

### Alipay (domestic) source details object

```javascript
{
    "returnUrl": "https://example.com"
}
```

| Field     | Required/Optional | Description                                                                                                             |
| --------- | ----------------- | ----------------------------------------------------------------------------------------------------------------------- |
| returnUrl | Required          | Where you will redirect your customer after the customer authorizes or cancels within the Alipay (domestic) experience. |

## Step 2: Create the Alipay (domestic) source using DigitalRiver.js

Use the DigitalRiver.js library to create and mount elements to the HTML container.

{% hint style="info" %}
The `address` object must contain postal code and state/province data that [adheres to a standardized format](/commerce-api/shopper-apis/cart/creating-or-updating-a-cart/providing-address-information.md) using the `state` attribute. Note that the `state` attribute listed below corresponds to the `countrySubdivision` attribute used when providing address information. The payment session manages the correct field name on the backend.
{% endhint %}

```javascript
let alipaySourceData = {
                "type": "alipay",
                "sessionId": "3c9473b0-630d-4f20-af61-63d3aa8acb35",
                "owner": {
                    "firstName": "Donglei",
                    "lastName": "Ye",
                    "email": "j2r23ux28qj@temporary-mail.net",
                    "phoneNumber": "13063725095",
                    "address": {
                        "line1": "Wei Bai Chang",
                        "city": "ShunDe District)",
                        "state": "Guangdong",
                        "country": "CN",
                        "postalCode": "528322"
                    }
                },
                "alipay": {
                    "returnUrl": redirectUrl
                }
            }
 
digitalriver.createSource(alipaySourceData ).then(function(result) {
    if (result.error) {
        //handle errors as something went wrong
    } else {
        var source = result.source;
     
        //do something with the created source
    }
});
```

### Alipay (domestic) source example

```javascript
{
    "clientId": "gc",
    "channelId": "drdod15",
    "liveMode": false,
    "id": "5ce08114-143b-4bf6-ae0e-6fc501ee0c24",
    "clientSecret": "5ce08114-143b-4bf6-ae0e-6fc501ee0c24_a468b08e-2c47-4531-82af-d48d80ff6dcc",
    "type": "alipay",
    "reusable": false,
    "owner": {
        "firstName": "Donglei",
        "lastName": "Ye",
        "email": "j2r23ux28qj@temporary-mail.net",
        "phoneNumber": "13063725095",
        "address": {
            "line1": "Wei Bai Chang",
            "city": "ShunDe District)",
            "state": "Guangdong",
            "country": "CN",
            "postalCode": "528322"    
        }
    },
    "amount": "10.00",
    "currency": "CNY",
    "state": "pending_redirect",
    "creationIp": "10.81.3.92",
    "createdTime": "2020-02-26T02:48:11.508Z",
    "updatedTime": "2020-02-26T02:48:11.508Z",
    "flow": "redirect",
    "redirect": {
        "redirectUrl": "https://api.digitalriverws.com:443/payments/redirects/51314834-9bf9-483f-b3a7-4b36a14d3f5c?apiKey=pk_hc_e03ee62c0d964bb3ac75595b1203d13c",
        "returnUrl": "returnUrl.com"
    },
    "alipay": {}
}
```

## Step 3: Authorize an Alipay (domestic) source

When you create an Alipay (domestic) source, the customer must authorize the charge through their payment provider. You can accomplish this by redirecting the customer to their payment provider.

### Redirecting the customer for authorization

Use the `redirectUrl` parameter in your `createResource` response to redirect your customer to the payment provider for authorization.

```javascript
window.location.href = sourceResponse.redirect.redirectUrl;
```

The payment provider will present the customer with the transaction details to authorize or cancel the transaction. A successful authorization redirects the customer to the Alipay Return URL parameter you specified when you created the source.

## Step 4: Use the authorized source

Once authorized, you can use the source by [attaching it to a cart](/commerce-api/payments/sources.md#attaching-a-payment-method-to-an-order-or-cart).

{% tabs %}
{% tab title="POST /v1/shoppers/me/carts/active/apply-payment-method" %}

```javascript
{
  "paymentMethod": {
    "sourceId": "e7ba0595-059c-460c-bad8-2812123b9313"
  }

```

{% endtab %}
{% endtabs %}

## Testing Alipay (domestic)
