This topic introduces the functions that Alipay+ MPM provides and guides you through how to use the APIs and SDKs to build an integration for these functions.

Before you begin

Before you learn more about how to integrate with Alipay+ MPM, ensure that you are familiar with the following things:

• The user experience that Alipay+ MPM can provide to customers. For more information, see Merchant-presented Mode Payment.
• General steps that you need to take to go through the whole integration process. For more information, see Get started with Alipay+ integration.

Build an integration

Use the APIs and SDKs that are provided by Alipay+ to integrate the following MPM functions as required:

Make a payment

To make payments to merchants, you need to take the following steps:

1. Filter and identify the code to determine whether the code can be processed by Alipay+.
2. Decode and send the code value to Alipay+ by calling the userInitiatedPay API. Alipay+ then returns the payment details to the MPP.
3. Render and present the cashier page to the user, where the payment details that are received in the previous step are displayed.
4. (Optional) If the paymentRedirectURL parameter is passed by Alipay+, redirect the user back to the merchant payment result page.

For more information about how to integrate related APIs or SDKs to make a payment, see Make a payment.

Return payment results

To return payment results to Alipay+, you need to integrate the inquirePayment and notifyPayment APIs. For more information about how to integrate the APIs, see Notify payment result and Respond to payment inquiry.

Cancel and refund

To support the users in refunding and canceling payments, you need to integrate the refund and cancelPayment APIs. For more information about how to integrate the APIs, see Cancel a payment and Refund.

More operations

Reconcile

Alipay+ provides multiple types of transaction reports to help MPPs to perform the clearing and settlement of transactions. MPPs can download and use reports to streamline their business workflows. For more information, see Reconcile.

Handle a dispute

Alipay+ provides related APIs to enable Mobile Payment Providers (MPPs) to initiate disputes after transactions occur and receive responses from Acquiring Service Providers (ACQPs). For more information about how to integrate the APIs, see Dispute.

More information

Go through the section below to obtain more information that empowers your integration:

• When using APIs to integrate, you need to take the following things into consideration:

• Make a POST request to the corresponding address with the identity information, signature, and business parameters in the HTTP request. For more information about the structure of a request and response, see API overview.
• To ensure message transmission security, the MPP must perform message signing and signature validation properly. When calling an Alipay+ API, the MPP must sign the API request and validate the response signature accordingly; when receiving an API call from Alipay+, the MPP must validate the request signature and sign the API response accordingly. For more information, see Sign a request and validate the signature.

• For the full list of APIs that are provided for MPM, see APIs and SDKs.
