notifyPayment (NFC Payment)MPP → Alipay+
The notifyPayment API allows the Mobile Payment Provider (MPP) to notify the payment result to Alipay+ when payment processing reaches a final state of success or failure.
Note: In the following sections, Mobile Payment Provider (MPP) is also known as Payment Service Provider (PSP). For example, the pspId parameter specifies the ID that identifies an MPP.
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 take one of the following actions:
- Exclude the parameters from the request body.
- Set the parameter 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 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:
- This field is an API idempotency field. Alipay+ regards the notifications with the same paymentRequestId as repeated and processes them only once. Alipay+ checks the consistency of the following key request parameters: paymentAmount, paymentResult, paymentId, payToAmount, and customerId. If any values differ from the previous notification, Alipay+ returns the REPEAT_REQ_INCONSISTENT result code.
- Maximum length: 64 characters
paymentId String
The unique ID that is assigned by the MPP to identify a payment order.
Specify this parameter if the value of the paymentResult.resultStatus parameter is S, which means that the payment succeeds.

The amount that Alipay+ requests to receive from the MPP. The currency of this amount must be the same as that used by Alipay+ to create the payment order. If a promotion exists, this amount does not include the promotion amount.
Specify this parameter if the value of the paymentResult.resultStatus parameter is S, which means that the payment succeeds.
payToAmount Amount
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. When this parameter is specified, payToAmount.value is calculated based on paymentAmount.value and paymentQuote.quotePrice by using the rounding mode of HALF EVEN.

The date and time when the payment order reaches a final state.
Specify this parameter if the value of the paymentResult.resultStatus parameter is S, which means that the payment succeeds.
