This documentation is for users who send HTTP/HTTPS POST requests through API URL.
URL of API requests is constructed by multiple parameters under sepesific request structure. In URL, there are public parameters, your signature and spesific parameters of target API. There is request sample code in each API documentation for your reference. But no URL sample is provided. You should encode by yourself before sending requests. Return result will be in response after signature in your request has been checked. When request handled successfully, parameters will be returned. Error code will be returned once the invokation is failed. You can diagnose failures according to the public error codes and errors of the specific API.
Tips：SDK is recommended. So that you don’t need to check the signature.
