Live Room Participant Status Callback Notification

Updated: 2025-07-17 12:24:21

Purpose

For institutions that need near-real-time awareness of whether students and teachers have entered the classroom on time, and if not, need to notify students by phone to attend class. With this feature, when the participant status in a channel's live room changes, the server will send a POST request to the callback URL set by the customer, submitting the data to the user-defined callback interface for notification.

Parameters included in the callback (sent via form-data request):

Parameter Type Description
logList string JSON array of objects
timestamp number Current timestamp
sign string Signature verification. Prepend and append "polyvlog". The middle consists of data keys and values, with keys sorted alphabetically in ascending order. After MD5 encoding, convert to uppercase. For example, if the parameters are {roomId:'200060', channelId:'005200060', user:{nick:'yang'}}, the signature is md5/('polyvlog'+'channelId'+'005200060'+'roomId'+'200060'+'user'+JSON.stringify({nick:'yang'})+'polyvlog').toLocaleUpperCase();

Notes

  • The callback aggregates data within a 1-minute interval for unified delivery.
  • Both new and old backend versions are supported.
  • Due to the high frequency of callbacks, which may put pressure on the customer's server, prior communication with the customer is required.
  • The interface returns a JSON object containing a code field. A value of 200 indicates success. If 200 is not returned, the system will retry 3 times; after 3 failed attempts, the log is discarded.
