notifyPaymentMPP → Alipay+
The notifyPayment API is used by the Mobile Payment Provider (MPP) to notify the payment result to Alipay+ when payment processing reaches a final state of success or failure.
Structure
A message consists of a header and body. The following sections are focused on the body structure. For the header structure, see:
Note:
1. Set the data type of each parameter (except array) as String. This means that you must use double quotation marks (" ") to enclose the parameter value. Examples:
- If the data type of a parameter is Integer and its value is 20, set it as "20".
- If the data type of a parameter is Boolean and its value is true, set it as "true".
2. For optional parameters that are not required in your case, you can:
- exclude them from the request body.
- set the values as null (without the double quotation marks).
Do NOT leave the optional parameters empty by setting their values as ""; otherwise, an error might occur.
Request parameters
paymentResult Result object REQUIRED
The result of the payment. The value of the paymentResult.resultStatus parameter represents the payment status, where S represents success and F represents failure. The value of the paymentResult.resultStatus parameter cannot be U when this API is called to send the payment result. See the Payment result codes table for more details.
paymentRequestId String REQUIRED
The unique ID that is assigned by Alipay+ to identify a payment order.
More information about this field
- This field is an API idempotency field.For requests that are initiated with the same paymentRequestId, Alipay+ regards the requests as repeated and processes the requests only once. Alipay+ checks the consistency of the following key request parameters: paymentAmount, paymentResult, paymentId, payToAmount, customerId, and customsDeclarationAmount. If any of their values is different from that in the previous request, Alipay+ returns the REPEAT_REQ_INCONSISTENT result code.
- Maximum length: 64 characters
paymentId String

Specify this parameter if the value of the paymentResult.resultStatus parameter is S, which means that the payment succeeds.

payToAmount Amount object
The amount that the MPP settles to Alipay+. The currency of the amount is the MPP's currency.
Specify this parameter if the value of the paymentResult.resultStatus parameter is S and payToAmount.currency is different from paymentAmount.currency.
