sendOTPAlipay+ → MPP
Alipay+ uses the sendOTP API to request that the Mobile Payment Provider (MPP) sends a one-time password (OTP) to the user. This API is used in risk control scenarios where the user identity needs to be verified with OTPs.
Note: In the following sections, the MPP is also known as PSP. For example, pspId refers to 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.

How to return the result
According to the request processing result, the MPP needs to return the corresponding result (specified by the result parameter):
- If the OTP sending succeeds, set the value of result.resultStatus to
S
and the value of result.resultCode toSUCCESS
. - If the OTP sending fails, set the value of result.resultStatus to
F
and the value of result.resultCode accordingly. - If the OTP sending result is unknown, set the value of result.resultStatus to
