| Note：WeChat Pay does not support API pressure testing on formal environment. API pressure testing on formal environment is usually recognized by the system as "invalid requests". Too many "invalid requests" will trigger interface restrictions, which will seriously lead to payment authority being closed. It is recommended that merchants with pressure testing requirements can use mock data to make simulation requests. WeChat Pay will provide the pressure testing tools for merchant in the future. | ||
