Interface Constraints

  1. The interface supports both HTTP and HTTPS. HTTPS is recommended to ensure interface security. API calls have frequency limits. See details

  2. The seminar scenario does not support modifying: live viewing template (template), low-latency live streaming switch (pureRtcEnabled), number of link mic users (linkMicLimit), maximum concurrent viewers (maxViewer)

  3. Legacy backend channels (scenario undefined newScene: undefined) do not support modifying: live viewing template (template)

Request Parameter Description

Parameter Required Type Description
appId true String Account appId See details for obtaining secret key

sign true String Signature, a 32-character uppercase MD5 value. The appSecret used to generate the signature is critical for communication data security. It must not be stored or used directly on the client side. 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, please download the relevant dependency source code. Click here to download source code. After downloading, add it to your own source code project. HttpUtil.java and LiveSignUtil.java in the test cases are included in the download 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.
