Create Seminar Channel (New Backend)

Updated: 2026-04-09 17:41:40

Legacy API endpoint Create Single Channel (Legacy)

Notes on Upgrading from Legacy to New API

  1. The legacy API allowed setting channel basic info and viewing conditions for external seminars directly when creating a channel.
  2. The new API only allows setting channel basic info when creating a channel. Viewing conditions are sourced from the default template settings. The default template must be configured before creating a channel.
  3. Modifications to the default template do not affect already created channels. Modifying existing channel info is consistent with the legacy API.

API Description

1、根据直播默认模板创建频道
2、(timestamp, appId)参与sign签名,并和sign一起通过url传递,请求体参数不参与签名,通过post请求体传递【请设置请求头contentType:application/json】
3、接口支持https协议

Online API Call

Request Method

POST

API Constraints

  1. The API supports both HTTP and HTTPS. HTTPS is recommended for security. API calls have rate limits. See details

  2. In a seminar scenario, the host password and attendee password cannot be the same.

Request Parameter Description

Parameter Required Type Description
appId true String Account appId See Get Secret Key
timestamp true Long Current 13-digit millisecond timestamp, valid for 3 minutes
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. 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

Request Body Parameter Description

name true String Live stream name, max length 100
newScene true String Live stream scene (seminar - seminar)

seminarAttendeePassword false String Seminar attendee password, only valid when the live scene is seminar. Length 6-16 characters. If not provided, it will be randomly generated by the system. The host password and attendee password cannot be the same.
recordMode false String Recording mode, only valid when the live scene is seminar. auto - automatic recording (default); manual - manual recording
seminarLiveType false String Meeting type, only valid when the live scene is seminar. private - internal seminar (default); public - external live stream
splashImg false String Cover image URL. Images not on a Polyv domain need to be uploaded via Upload All Channel Decoration Image Materials
categoryId false Integer Category ID, can be obtained via the "Query Live Categories" API
startTime false Long Start time, timestamp, e.g., 1629734400000
subAccount false String Sub-account email. If provided, the channel will be created under this sub-account (the sub-account cannot be deleted or disabled). Currently cannot be obtained via API.
linkMicLimit false Integer Number of participants
1-47: represents the number of participants

Java Request Example

For quick integration of the base code, please download the relevant dependency source code. Click here to download the 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 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.
