# Chat Channels

This page explains how a Digital Expert can connect to different conversation channels through triggers while reusing the same agent workflow capabilities.

## Supported conversation channels

Besides being used directly in the in-platform chat interface, a Digital Expert can enter the same workflow through different Trigger channels:

* **In-platform chat channel (Chat Trigger)**: The flow is triggered when users submit questions in the platform chat window.
* **[Scheduled channel (Schedule Trigger)](../plugin/trigger/schedule-trigger/)**: The system triggers the Digital Expert on a Cron schedule for fixed tasks (such as daily summaries or inspection reminders).
* **[Lark channel (Lark Trigger)](../plugin/trigger/lark-trigger/)**: Users send messages in Lark, and the Lark trigger routes them to the corresponding Digital Expert.
* **[WeCom channel (WeCom Trigger)](../plugin/trigger/wecom-trigger/)**: Users send messages in WeCom, and WeCom Trigger routes them to the corresponding Digital Expert.
* **[DingTalk channel (DingTalk Trigger)](../plugin/trigger/dingtalk-trigger/)**: Users send direct or group messages in DingTalk, and DingTalk Trigger routes them to the corresponding Digital Expert.

## Integration principles

These channels share the same Digital Expert configuration:

* Agent orchestration
* Toolset and tool authorization
* Knowledge base and retrieval logic

The differences are mainly in trigger timing and input source, not in the core workflow execution.
