inquiryCodeRulesMPP → Alipay+
In the Cashier Payment or the Merchant-presented Mode Payment scenario, this API is used by the Mobile Payment Provider (MPP) to inquire about Alipay+ code rules. If the request succeeds, the MPP obtains Alipay+ code rules and saves them on its server. When receiving a code, the MPP then uses the code rules locally to identify whether the code can be processed by Alipay+.
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.
