Callback After Creating Single Chat Conversation

Functional Description

The App business server can operate on users' single chat messages in real-time through this callback, such as:

• Recording the creation of single chat conversations in real-time (logging or synchronizing to other systems).

Precautions

• To enable the callback, you must configure the callback URL and turn on the switch corresponding to this callback protocol. See the Callback Description document for configuration methods.
• The callback direction is an HTTP/HTTPS POST request initiated by OpenIMServer to the App backend.
• The APP business server must respond to this request within the timeout period.

Scenarios That May Trigger This Callback

• App users create a single chat conversation through the client.
• App administrators create a single chat conversation through REST API.

Timing of Callback

• After OpenIMServer receives a message that a user has created a single chat conversation and before delivering the message to the target user.
