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+ does not 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.
