Online API Call

Request Method

POST

API Constraints

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

Request Parameter Description

Parameter	Required	Type	Description
appId	true	String	Account appId See details: Get Secret Key
timestamp	true	Long	Current 13-digit millisecond timestamp, valid within 3 minutes
sign	true	String	Signature, a 32-character uppercase MD5 value. `The appSecret key used to generate the signature is critical for communication data security. It must never 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 details: Signature Generation Rules
channelId	true	String	Channel ID
pullBitRate	true	Integer	Channel pull stream bitrate limit. Refer to the "Channel Pull Stream Bitrate Limit pullBitRate Value Description" for details.

Channel Pull Stream Bitrate Limit pullBitRate Value Description

Value	Description
-1	No limit, uses original bitrate for pull stream
400	Pull stream at 400 bitrate
600	Pull stream at 600 bitrate
800	Pull stream at 800 bitrate
1000	Pull stream at 1000 bitrate
1500	Pull stream at 1500 bitrate
2000	Pull stream at 2000 bitrate
2500	Pull stream at 2500 bitrate

Example

Response Parameter Description

Parameter	Type	Description
code	Integer	Status code, same as HTTP status code, used to determine the basic response status
status	String	Response result, determined by the business. Returns "success" on success, "error" on failure
success	Boolean	Whether the response was successful
requestId	String	Request ID, a unique UUID generated for each request. Only used for troubleshooting and debugging, should not be tied to business logic
error	Object	Error information when status code is not 200 See details: Error Field Description
data	Object

Java Request Example

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