Migration Guide for AMS to Alipay+
Overview
This guide is designed to facilitate your migration journey from AMS to Alipay+. You can find changes in terms of business, products, and API integration, as well as other important information about the migration.
AMS: Alipay Merchant Service, a set of APIs offered by Global Site for Acquiring Service Providers (ACQPs) to enable Alipay+ payments.
Alipay+: Alipay Participant Service, a set of APIs offered by Alipay+ for both Acquiring Service Providers (ACQPs) and Mobile Payment Providers (MPPs) to enable Alipay+ payments.

- Integrate Alipay+ APIs.
- Migrate your existing merchants and business from AMS to Alipay+.

User-presented Mode Payment, Merchant-presented Mode Payment (Entry Code, Order Code, Private Order Code)
AMS and Alipay+ share the same payment scenarios as follows:
- User-presented Mode Payment (UPM)
- Merchant-presented Mode Payment - Entry Code (MPM Entry)
- Merchant-presented Mode Payment - Order Code (MPM Order)
After migration, the only difference is that Alipay+ supports Private Order Code in Merchant-presented Mode Payment, which is issued by ACQP instead of Alipay+.
- Merchant-presented Mode Payment - Private Order Code (MPM Private Order)
The user scans the QR code presented by the merchant to complete the payment. In this mode, the QR
code is a dynamic order code issued by ACQP.
Private Order Code has the following format: https://my.domain.com/{CGCP code}
Order Code (issued by Alipay+) is only the CGCP code
Notes: Try to avoid using Private Order Code unless necessary, because some Alipay+ wallets may not be able to recognize this type of code without app or configuration upgrade.
The differences and commonalities between AMS and Alipay+ in terms of User-presented and Merchant-presented Mode Payment APIs are illustrated below.

Reports and Reconciliation
AMS and Alipay+ provide clearing transaction reports and settlement reports for reconciliation. Please pay attention to the following differences.
- In Alipay+, you can find transaction batches of the settlement in the settlement report. A settlement report refers to a piece of remittance to the ACQP's banking account. The settlement batch IDs index all the transaction details. Alipay+ doesn't provide the settlement items report which is provided by AMS.
- Alipay+ introduces the concept of fund direction: Credit and Debit. Credit refers to an addition to the to-be-settled amount, and Debit refers to a deduction from the to-be-settled amount.
- In Alipay+, fee items consist of a refundable interchange fee and a non-refundable service fee. Please note that the service fee is non-refundable.
- Alipay+ generates unified reports based on settlement currency instead of wallets.
The differences and commonalities between AMS and Alipay+ in terms of Reports and Reconciliation are illustrated below.
