Integrate the Alipay+ SDK

You can integrate the Alipay+ SDK into your client side to consult the payment method information, which includes:

Whether the Ailpay+ payment method is available.
If available, one or multiple Alipay+ logos and detailed logo information, including the logo URLs and the logo width and height.
If available, the Alipay+ promotion campaign names in multiple languages.

The Alipay+ SDK consists of the mobile SDK and the Web/WAP SDK. The following table shows the terminal types that are supported by different SDK types.

SDK type	Terminal type
SDK type	Web	WAP	App
Mobile SDK	🔲	🔲	✅ Recommended for app
Web/WAP SDK	✅	✅	✅

The consultation workflow differs depending on the SDK type that you use.

Use the mobile SDK

The following figure illustrates the main workflow of how to consult the payment method information by using the mobile SDK.

Figure 2. Consult payment method information through the mobile SDK

The workflow contains the following major steps:

When the user places an order, your client side needs to obtain the payment method information as follows:

1.1 Call your server side to obtain the payment method list (Step 1-5);

1.2 Call the inquirePaymentOption API provided by the mobile SDK to obtain information about the Alipay+ payment method with the params parameter and the completionHandler parameter (Step 6).

Alipay+ returns a response that includes the following information (Step 8-9):

If the API call is accepted and the value of the paymentOption.enabled parameter is true, the Alipay+ logo, the brand name, and the promotion information are specified on the paymentOption parameter.

Your client side renders the payment method page by using the result returned by your server side and Alipay+ (Step 10).

Processing logic

When you call the inquirePaymentOption API, take the following things into consideration:

Prerequisites

Call the setConfiguration API to set up the SDK with the following parameters before you use other APIs: merchantId, acquirerId, language, and envType.
The merchantId must be the same as the merchantInfo.referenceMerchantId that is specified in the registration API request.
The acquirerId is assigned by Alipay+ to identify an ACQP.

How to handle the output parameters

If the value of the paymentOption.enabled parameter is false in the callback, this indicates that the Alipay+ payment method is not available for this transaction.
If the value of the paymentOption.enabled parameter is true in the callback, this indicates that the Alipay+ payment method is available and you need to display the Alipay+ logo, the brand name, and the promotion information (if any) on the payment method page.

If no aggregated logo is preconfigured, the default Alipay+ logo is returned. You need to display the default Alipay+ logo along with the promotion information (if any).
If aggregated logos are preconfigured, one or more aggregated logos are returned.

The aggregated logos are returned based on the currency specified in the input parameter. If no aggregated logo matches the currency, the default aggregated logo is returned.
If the aggregated logos include the promotion tag, you can directly display these logos; otherwise, you need to display the aggregated logos along with the promotion information (if any).

Samples

setConfiguration
The following sample code shows how to call the setConfiguration API.

iOS

copy
IAPConfiguration *configuration = IAPConfiguration.new;
configuration.envType = @"PROD";
configuration.acquirerId = @"xxx";
configuration.merchantId = @"yyy";
configuration.language= @"zzz";

[[AlipayPlusClient shared] setConfiguration:configuration];

Android

copy
IAPConfiguration configuration = new IAPConfiguration();
configuration.envType = "SANDBOX";
configuration.acquirerId = "XXX";
configuraiton.merchantId = "YYY";
configuration.language = "ZZZ";

AlipayPlusClient.setConfiguration(configuration);

inquirePaymentOption

The following sample code shows how to call the inquirePaymentOption API.

iOS

copy
IAPInquirePaymentOptionParams *params = IAPInquirePaymentOptionParams.new;
params.paymentCurrency = @"PHP";
[[AlipayPlusClient shared] inquirePaymentOptionWithParams:params 
completionHandler:^(IAPPaymentOption *paymentOption, NSError *error) {
if (!error && paymentOption.enabled) {
// show cashier page with Alipay+ payment method
} else {
// show cashier page with no Alipay+ payment method
}
}

Android

copy
IAPInquiryPaymentOptionParams params = new IAPInquiryPaymentOptionParams();
params.paymentCurrency = "PHP";
AlipayPlusClient.inquiryPaymentOption(context, params, new IAPInquiryPaymentCallback() {

    @override
    public void onSuccess(IAPPaymentOption paymentOption) {

        //show cashier page with Alipay+ payment method
    
    }
    
    public void onFailure(String errorCode, String errorMessage) {
    
        //show cashier page with no Alipay+ payment method
    
    }

});

1.2 Call the inquirePaymentOption API provided by the Web/WAP SDK with the paymentCurrency parameter (Step 6).

Processing logic

When you call the inquirePaymentOption API, take the following things into consideration:

Prerequisites

Call the AlipayPlus.create() method of the Web/WAP SDK with the following parameters to create an instance during system initialization: merchantId, acquirerId, language, and envType.
The merchantId must be the same as the merchantInfo.referenceMerchantId that is specified in the registration API request.
The acquirerId is assigned by Alipay+ to identify an ACQP.

How to handle the output parameters

If the value of the paymentOption.enabled parameter is false, this indicates that the Alipay+ payment method is not available for this transaction.
If the value of the paymentOption.enabled parameter is true, this indicates that the Alipay+ payment method is available and you need to display the Alipay+ logo, the brand name, and the promotion information (if any) on the payment method page.

If no aggregated logo is preconfigured, the default Alipay+ logo is returned. You need to display the default Alipay+ logo along with the promotion information (if any).
If aggregated logos are preconfigured, one or more aggregated logos are returned.

The aggregated logos are returned based on the currency specified in the input parameter. If no aggregated logo matches the currency, the default aggregated logo is returned.
If the aggregated logos include the promotion tag, you can directly display these logos; otherwise, you need to display the aggregated logos along with the promotion information (if any).

Samples

AlipayPlus.create()

The following sample shows how to call the AlipayPlus.create() method:

copy
const alipayPlus = AlipayPlus.create({
  acquirerId: 'xxx',
  merchantId: 'yyy',
  language: 'en_US',
  envType: 'SANDBOX',
});

inquirePaymentOption()

The following sample shows how to call the inquirePaymentOption() API:

copy
alipayPlus.inquirePaymentOption({
  paymentCurrency: 'PHP',
}).then((paymentOption) => {
  // show cashier page with Alipay+ payment method
});
