It must not be stored on the client side for direct use. All APIs must be called through the customer's own server to relay requests to the POLYV server for response data.` See signature generation rules

Java Request Example

For quick integration of basic code, download the relevant dependency source code. Click to download source code. After downloading, add it to your own source project. The test cases include HttpUtil.java and LiveSignUtil.java in the downloaded file.

It is strongly recommended to use the Live Java SDK for API integration. The Live Java SDK provides unified encapsulation and optimization for API call logic, exception handling, data signing, and HTTP request thread pools.
