Features before & after the migration

Integration differences between AlipayCN and Alipay+

Migration solutions from AlipayCN to Alipay+

Cashier Payment

Migrate existing merchants to Alipay+

AlipayCN SDK is integrated into the merchant app

AlipayCN integration document link: Cross-border APP Payment

Before: The merchant sends the order to the ACQP to obtain the orderstr parameter and uses the orderstr parameter to call the AlipayCN SDK's pay method to process the payment.

After: The merchant sends the order to the ACQP to obtain the schemeUrl parameter, and uses the schemeUrl parameter to redirect the user to the AlipayCN app to process the payment. The merchant handles the redirection to the AlipayCN app on its own.

AlipayCN SDK is not integrated into the merchant app

AlipayCN integration document link: Cross-border APP Payment

Before: The merchant sends the order to the ACQP to obtain the WAP redirection URL that leads to a WAP page, where the user can open the AlipayCN app, download the AlipayCN app, or log in to pay.

After: The merchant sends the order to the ACQP to obtain the schemeUrl parameter, and uses the schemeUrl parameter to redirect the user to the AlipayCN app to process the payment. The merchant handles the redirection to the AlipayCN app on its own.

Cashier Payment for Merchant WAP page

AlipayCN integration document link: Cross-border WAP Payment

Before: The ACQP constructs the redirection URL that leads to a WAP page, where the user can open the AlipayCN app, download AlipayCN app, or log in to pay. The AlipayCN page handles the subsequent process.

After: The merchant sends the order to the ACQP to obtain the schemeUrl parameter, and uses the schemeUrl parameter to redirect the user to the AlipayCN app to process the payment.

Cashier Payment for Merchant WEB page

AlipayCN integration document link: Cross-border Website Payment

Scenario 1

Before: The merchant sends the order to the ACQP, the ACQP constructs the redirection URL to the AlipayCN Web page (that supports login-to-pay) and returns the redirection URL to the merchant. The merchant then redirects the user to the AlipayCN Web page.

After: After the merchant sends the order to the ACQP, the ACQP sends the order to Alipay+. Alipay+ returns the redirection URL to the Alipay+ cashier page, which supports scan-to-pay. The user can use the AlipayCN app to scan and pay, without login to the Web page.

Scenario 2

Before: After the merchant sends the order to the ACQP, the ACQP returns its own QR code to the merchant. The merchant displays the QR code to the user, who scans the code with the AlipayCN app to invoke the app's cashier page.

After: No change on the merchant side. The ACQP needs to identify the wallet's User Agent (UA) and routes the order to Alipay+. The ACQP must send its domain name to Alipay+ to be added to a whitelist.

Fastest migration solution of Cashier Payment for merchants

• For both SDK and non-SDK scenarios, the ACQP provides the same payment API to the merchant, so the merchant need not be concerned about the parameters after placing the order.
• The payment API that the ACQP provides to the merchant does not disclose the wallet channel and packages all the redirection URLs for different terminals as one parameter.
• The only change on the merchant side is that, after sending the order and receiving the response, the merchant opens the AlipayCN app directly by using the returned URL scheme, instead of using the SDK to invoke the AlipayCN app. See sample code below:

Before: call the SDK to open the AlipayCN app.
-(void)payOrder:(NSString *)orderStr fromScheme:(NSString *)schemeStr callback:(CompletionBlock)completionBlock;

After: Open the AlipayCN app directly.
NSString *applinkUrl = @"Your AppLinkUrl";
NSString *schemeUrl = @"Your SchemeUrl";
NSString *normalUrl = @"Your NormalUrl";
NSString *targetUrl;

UIApplication *application = [UIApplication sharedApplication];

if ([application canOpenURL:[NSURL URLWithString:schemeUrl]]) {
    targetUrl = schemeUrl;
} else if ([application canOpenURL:[NSURL URLWithString:applinkUrl]]) {
    targetUrl = applinkUrl;
} else {
    targetUrl = normalUrl;
}


// applink or scheme
if (@available(iOS 10.0, *)) {
    [application openURL:[NSURL URLWithString:targetUrl] options:@{} completionHandler:^(BOOL success) {
        if (success) {
            // do something.
        }
    }];
} else {
    [application openURL:[NSURL URLWithString:targetUrl]];
}

Auto Debit

AlipayCN integration document link: Auto-debit Payment

Before: AlipayCN's authorization API provides the auth ID (the agreement_no parameter) with which the merchant can use for funds capture.

After: Alipay+ uses Oauth2.0, which is different from the authorization process of AlipayCN. See the following notes for details:

Notes on migration from AlipayCN to Alipay+:

• When AlipayCN users initiate an unbinding, AlipayCN will not call the consultUnbindng API to ask the merchant for permission, but process the unbinding directly.

• It is recommended that the merchant completes the due capture before providing the actual merchandise/service, or limits the user's overdraft amount.
• Since AlipayCN can complete the unbinding independently, the ACQP needs to integrate the authNotify API to obtain information about the unbinding.

• AlipayCN does not have a WAP page for the authorization. If the user starts the authorization from the merchant's WAP page with a browser other than the user's default browser, the redirection back from AlipayCN to the merchant will fail, so the authorization fails. To ensure the authorization success, the ACQP must integrate the authNotify API to obtain the authCode.

Third-party Merchant QR Code Payment

AlipayCN integration document link: Third-party Merchant QR Code Payment

Before: The ACQP routes the order to AlipayCN according to AlipayCN's UA.

• Before the merchant migration (merchants use the AlipayCN channel for transaction before, but after migration, they use the Alipay+ channel), identify AlipayCN according to AlipayCN's UA.

Change: The ACQP routes the order to Alipay+ according to the Alipay+ wallet's UA. Alipay+ wallet's UA includes AlipayCN.

• After the merchant migration, identify Alipay+ wallets according to AlipayCN's UA and Alipay+ wallet's UA.

Alipay+ wallet's UA: AlipayConnect, KAKAOTALK, and PAYAPP

AlipayCN's UA: AlipayClient

The routing strategy differs according to the wallets, migration progress, merchant's willingness, and Alipay+ services:

• For transactions with wallets using the UAs above:

• For ACQPs that have integrated AlipayCN

• AlipayCN transactions

• Meet all of the conditions: The ACQP has migrated from AlipayCN to Alipay+; the merchant has migrated; the Alipay+ channel is opened.

• Route transactions to Alipay+.

• Meet one of the conditions: The ACQP has not migrated from AlipayCN to Alipay+; The merchant has not migrated; the Alipay+ channel is not opened.

• Route transactions to AlipayCN.

• Transactions with wallets other than AlipayCN: Route transactions to Alipay+.

• For ACQPs that have no integrated AlipayCN: Route all transactions to Alipay+.

• For transactions with wallets not using the UAs above: The ACQP handles transactions according to the wallet's routing rules. Try to avoid conflicts.

Merchant QR Code Payment

AlipayCN integration document link: Merchant QR Code Payment

Before: A merchant obtains the AlipayCN's static merchant QR code in advance and displays the code for customers to scan and pay.

After: Alipay+ does not provide merchant QR codes. Merchant-presented Mode Payment Entry Code is used instead.

Transaction QR Code Payment

AlipayCN integration document link: Transaction QR Code Payment

Before: The ACQP sends the order to AlipayCN to obtain an order code.

After: The ACQP sends the order to Alipay+ to obtain an order code.

No change on the merchant side for this scenario. The ACQP needs to migrate to Alipay+.

Barcode Payment

AlipayCN integration document link: Barcode Payment

Before:

After: Route all codes with a length of 16~24 digits and starting with 25~30 to Alipay+ after migration.

Note: For User-present Mode Payment, AlipayHK payment codes and AlipayCN payment codes are not processed differently, so before the transaction with AlipayHK can be started, the migration from AlipayCN to Alipay+ must be completed.

After the ACQP completes the migration, migrate the merchants in batches, according to their willingness, integration status, migration schedule, and registration status, so transaction flows directly connected with the AlipayCN channel are migrated to the Alipay+ channel.

Migration process for AlipayCN ACQPs to Alipay+

Preparations

For ACQPs that have integrated with AlipayCN, provide the following information to your Alipay+ Solution Architect (SA):

• Decide your migration solution. If you meet any of the following scenarios:

• MS (merchant ID and store ID) has changed.
• Individual merchants need to be migrated.
• You do not commission Alipay+ for the migration.

Then you need to submit a mapping table for the merchant's PMS (partner ID, merchant ID, and store ID) before & after the migration, and proactively register the merchants again. If no MS is changed, decide whether to commission Alipay+ for the migration. If Alipay+ is commissioned for the migration, you need to use an email to authorize Alipay+ to handle your data in AlipayCN.

• Discuss with Alipay+ your schedule for the data migration.
• Decide your refund solution.
• Provide the new KYB information to Alipay+.
• If you have integrated AlipayCN's Credit Pay Installment, ensure that you sign a new contract for Credit Pay Installment after the migration.
• If multiple fee rates exist in your AlipayCN channel, you need to define the new fee rate IDs and fee rate values in advance.

Note: These preparations are skipped for ACQPs that have not integrated with AlipayCN before.
