Channel docking is call forwarding for one OpenClaw session. It keeps the same conversation context, but changes where future replies for that session are delivered.

​
Example

Alice can message OpenClaw on Telegram and Discord: 
{
  session: {
    identityLinks: {
      alice: ["telegram:123", "discord:456"],
    },
  },
}
If Alice sends this from Telegram: 
/dock_discord
OpenClaw keeps the current session context and changes the reply route:
Before dockingAfter /dock_discord
Replies go to Telegram 123Replies go to Discord 456
The session is not recreated. The transcript history stays attached to the same session.

​
Why use it

Use docking when a task starts in one chat app but the next replies should land somewhere else. Common flow:
  1. Start an agent task from Telegram.
  2. Move to Discord where you are coordinating work.
  3. Send /dock_discord from the Telegram session.
  4. Keep the same OpenClaw session, but receive future replies in Discord.

​
Required config

Docking requires session.identityLinks. The source sender and target peer must be in the same identity group: 
{
  session: {
    identityLinks: {
      alice: ["telegram:123", "discord:456", "slack:U123"],
    },
  },
}
The values are channel-prefixed peer ids:
ValueMeaning
telegram:123Telegram sender id 123
discord:456Discord direct peer id 456
slack:U123Slack user id U123
The canonical key (alice above) is only the shared identity group name. Dock commands use the channel-prefixed values to prove that the source sender and target peer are the same person.

​
Commands

Dock commands are generated from loaded channel plugins that support native commands. Current bundled commands:
Target channelCommandAlias
Discord/dock-discord/dock_discord
Mattermost/dock-mattermost/dock_mattermost
Slack/dock-slack/dock_slack
Telegram/dock-telegram/dock_telegram
The underscore aliases are useful on native command surfaces such as Telegram.

​
What changes

Docking updates the active session delivery fields:
Session fieldExample after /dock_discord
lastChanneldiscord
lastTo456
lastAccountIdthe target channel account, or default
Those fields are persisted in the session store and used by later reply delivery for that session.

​
What does not change

Docking does not:
  • create channel accounts
  • connect a new Discord, Telegram, Slack, or Mattermost bot
  • grant access to a user
  • bypass channel allowlists or DM policies
  • move transcript history to another session
  • make unrelated users share a session
It only changes the delivery route for the current session.

​
Troubleshooting

The command says the sender is not linked. Add both the current sender and the target peer to the same session.identityLinks group. For example, if Telegram sender 123 should dock to Discord peer 456, include both telegram:123 and discord:456. The command says no active session exists. Dock from an existing direct-chat session. The command needs an active session entry so it can persist the new route. Replies still go to the old channel. Check that the command replied with a success message, and confirm the target peer id matches the id used by that channel. Docking only changes the active session route; another session may still route elsewhere. I need to switch back. Send the matching command for the original channel, such as /dock_telegram or /dock-telegram, from a linked sender.
