Upgrade from Cashier Payment tile mode

This topic is designed to help you upgrade Cashier Payment tile mode to the Alipay+ Unified Payment edition. It introduces the user experience changes and new features brought by the Alipay+ Unified Payment edition of Cashier Payment and provides a step-by-step guide to help you complete the upgrade.

Overview

Compared with the tile mode, the Alipay+ Unified Payment edition enhances the user experience and offers more features.

User experience

The following sections list the main kinds of user experience that a user might have with Cashier Payment.

For different merchant platforms, the user experience is different. The merchant platform can be a PC website (referred to as "Web" below) or a mobile app/WAP page (referred to as "Mobile" below).

  • If the user places the order on a Mobile page, the user is redirected to the Mobile Payment Provider (MPP) app or WAP page to continue the payment process.
  • If the user places the order on a Web page, the user is redirected to a page that displays a QR code. Depending on whether the MPP app supports code scanning, the payment experience varies:
    • If the MPP app supports code scanning, the user scans the code and completes the payment by using the MPP app.
    • Otherwise, the user is redirected to a series of WAP pages to go through the payment process, including login and paying with a password.

Mobile

This section introduces the user experience of Cashier Payment with Alipay+ unified payment method on mobile platforms. After placing an order on the merchant platform, the user selects the payment method to complete the payment, and the scenarios thereafter are listed as follows:

  • The user selects Alipay+ unified payment method as the payment method.
    • Scenario 1. The user goes to the Alipay+ WAP checkout page to select an MPP and proceeds.
    • Scenario 2. For the merchant app integrated with Alipay+ client SDK, a prebuilt Alipay+ checkout sheet pops up, where the user selects an MPP and proceeds.
  • Scenario 3. The user selects a specific MPP as the payment method.

For details about these scenarios, see the following sections.

Upgrade guide

Compared with the integration guide for Cashier Payment tile mode, you need to upgrade your implementation to accept payments in the following two steps:

Render the payment method page

To support the Alipay+ unified payment method, you need to consult the Alipay+ CDN server to obtain the Alipay+ logo and promotion information.

Workflow

The following figure illustrates the workflow of rendering the payment method page after the upgrade.

The following table compares the steps to render the payment method page before and after the upgrade:

Step

Before the upgrade

After the upgrade

Your server side calls the consultPayment API to consult payment method information.

In response, Alipay+ returns the list of available MPPs.

For more information, see Render the payment method page.

The steps are the same as before the upgrade.

6-7

Not required

Consult Alipay+ unified payment method information via CDN.

In response, Alipay+ returns the Alipay+ logo and promotion information (if any).

Alipay+ provides the following three methods for you to consult the information about the Alipay+ payment method. For more information, see How to consult payment method information.

Your server side returns the list of available MPPs to your client side.

Your server side returns the list of available MPPs and Alipay+ unified payment method information to your cilent side.

Workflow

The following figure illustrates the workflow of initiating a payment after the upgrade.

Figure 7. Workflow of initiating a payment

The following table compares the steps to initiate a payment before and after the upgrade:

Step

Before the upgrade

After the upgrade

1-7

Your server side calls the pay API with the following parameters:

  • paymentMethodType: the payment method that the user selects
  • terminalType: the terminal type of your client side

In response, Alipay+ returns the payment URL of the payment confirmation page to your server side.

After obtaining the payment URL from your server side, your client side redirects the user to the MPP side to confirm the payment.

For more information, see Initiate a payment and Redirect the user to the wallet.

In this case, the user selects a specific payment method. The steps are the same as before the upgrade.

9-18

N/A

In this case, the user selects the Alipay+ unified payment method.

Your server side calls the pay API with the following parameters:

  • paymentMethodType: CONNECT_WALLET
  • terminalType: the terminal type of your client side

In response, Alipay+ returns the URL of the Alipay+ checkout page and, if your client side is an app, the paymentData.

Your client side uses one of the following ways to open the Alipay+ checkout page, where the user selects a specific payment method and then gets redirected to the MPP side to confirm the payment.

  • If your client side is an app, it is recommended that your client side integrates the SDK provided by your server side to smoothly open the prebuilt Alipay+ checkout page. For more information, see How to open Alipay+ checkout page with SDK.
  • Alternatively, your client side can open the Alipay+ checkout page by using the URL that is returned by your server side. For more information, see Non-SDK integration solution.

For more information about the parameter differences between when the user selects a specific payment method and when the user selects the Alipay+ unified payment method, see the following excel file: 📎Parameter differences.xlsx.
