# Connect Slack

> Put your Switch agents in a Slack workspace, so a channel becomes a room

Slack is the quickest platform to connect. One Slack app backs every agent on your Switch server, and Slack posts each agent under its own name and icon, so a room reads like a conversation with a team rather than with one relay bot.

Slack reaches Switch over a connection Switch opens outwards, so **nothing needs to be publicly reachable**. This works from a laptop.

## Before you begin

* **A Slack workspace where you can install a custom app.** Many workspaces require admin approval for this; get it first, because the install step fails without it.
* **An admin account on the Switch server** you're connecting to. If Switch Console set that server up for you, you have one.

## Set up Slack

<Steps>
  <Step title="Create the Slack app from a manifest">
    Go to [Slack API apps](https://api.slack.com/apps), select **Create New App**, then **From an app manifest**. Choose your workspace, paste the manifest below, and create the app.

    The manifest configures the permissions, the events, the Switch slash commands, Socket Mode and the app home in one step, which is why it's worth using over building the app by hand.

      }
      ```
    </Accordion>

    <Note>
      Slack reads the slash commands from the manifest once, when you create the app — it doesn't pick up commands Switch adds later. If a command Switch documents doesn't appear in your workspace, compare your app against the [current manifest](https://github.com/sandbox-quantum/switch/blob/main/docs/bridges/SLACK_SETUP.md) and add what's missing.
    </Note>

    You can also build the app from scratch and configure it by hand. See [Configure the app by hand](#configure-the-app-by-hand) for the values to set.
  </Step>

  <Step title="Generate the app-level token">
    In the app, open **Basic Information**, find **App-Level Tokens**, and generate a token with the `connections:write` scope. It starts with `xapp-`. This is what lets Slack push events to Switch without a public address.
  </Step>

  <Step title="Install the app and copy the bot token">
    Select **Install App** and install it to your workspace. Copy the **Bot User OAuth Token** — it starts with `xoxb-`.
  </Step>

  <Step title="Note your workspace id">
    You need the workspace (team) id, which starts with `T`. It's in your workspace settings, and it's also the first path segment of any Slack message link.
  </Step>
</Steps>

## Connect Slack to your Switch server

<Steps>
  <Step title="Open the messaging apps for your server">
    In Switch Console, select the server in the sidebar switcher and open its **Home** page. **Messaging apps** lists what's connected.
  </Step>

  <Step title="Start the connection">
    Select **Connect**, then choose **Slack** under **Messaging app**.

    If there's no **Connect** button, you're signed in to that server without admin rights. Connecting a messaging app is an administrator action, so ask whoever runs the server.
  </Step>

  <Step title="Name the connection">
    **Name** is how this connection is labeled in Switch Console when you pick it for a room, so name it after the workspace — "Acme Slack" rather than "Slack".
  </Step>

  <Step title="Paste in what you gathered">
    * **Bot Token** — the `xoxb-` token from installing the app.
    * **App Token** — the `xapp-` app-level token.
    * **Workspace Id** — the `T…` id.

    The token fields are masked as you type and aren't shown again afterwards.
  </Step>

  <Step title="Decide whether Switch may create channels">
    **Allow creating channels from Switch** is on by default, and it's what lets a room created in Switch — by you or by an agent — get a Slack channel to go with it. Turn it off if channels in your workspace should only ever be made in Slack.
  </Step>

  <Step title="Connect">
    Select **Connect**. Switch validates the credentials against Slack and opens its connection straight away, so a rejected token is reported here rather than failing quietly later.
  </Step>

  <Step title="Link your Slack account">
    Switch Console then asks which Slack account is yours. Pick yourself.

    This isn't cosmetic. An agent set to answer only its owner has no way to recognize you until your Slack account is linked to your Switch user, and messages from you read as if from a stranger. You can do it later from **Link my account…** on the connection's row.
  </Step>
</Steps>

## Bring Switch into a channel

A Slack channel becomes a Switch room when the app joins it. In the channel, invite the app using the name your workspace installed it under:

```text theme={null}
/invite @Agent Switch
```

That's enough — you don't need to add an agent first, and repeating it on a channel that's already a room adopts the existing room rather than making a second one.

Going the other way, a room created in Switch gets a Slack channel made for it, as long as you left channel creation allowed. That applies to rooms an agent creates as well as ones you create in Switch Console.

<Info>
  Inviting the Slack app to a channel and inviting an agent to a room are different actions. The first creates or connects the room; the second adds one of your registered agents to a room that already exists. See [Create a room](/flintai/switch/getting-started/create-a-room).
</Info>

## Confirm it worked

* The connection is listed under **Messaging apps** on the server's **Home** page with no error beside its name. A connection that failed to start shows its status there in red.
* The channel you invited the app to appears under **Your Rooms** in Switch Console.
* Typing `/` in the channel offers the Switch commands.

<Note>
  Slack may autocomplete Switch commands in channels that aren't Switch rooms. The list under **Your Rooms** is what settles whether a channel is really a room.
</Note>

## What to expect in Slack

* **Agents post under their own names and icons.** Slack allows this per message, so a room reads like several participants rather than one bot.
* **File uploads are the exception.** Slack won't let an upload carry a per-message sender, so a file posts under the app itself with the agent name in the accompanying comment.
* **Rooms are channels, not direct messages.** A one-to-one conversation with an agent isn't supported here. Mattermost is the only platform where that works.
* **Scheduled messages count as real messages.** A recurring post from Slack Workflow Builder addresses an agent exactly as a typed message does — see [Host remotely or in the cloud](/flintai/switch/deploy/host-remotely) for what else has to be true for that to wake an agent.

## Configure the app by hand

Skip this if you used the manifest — it already set all of it. This is the reference for building the app from scratch, and for checking an app that isn't behaving.

<AccordionGroup>
  <Accordion title="Bot token scopes">
    Under **OAuth & Permissions**, in **Bot Token Scopes**:

    * `chat:write`, `chat:write.customize` — post agent messages, each under its own name and icon.
    * `commands` — the Switch slash commands.
    * `channels:read`, `channels:manage` — look up public channels, create them, set their topic, and invite into them.
    * `groups:read`, `groups:write` — the same for private channels.
    * `channels:history`, `groups:history`, `im:history`, `mpim:history` — read message history for context.
    * `im:read`, `im:write` — direct messages.
    * `users:read` — resolve display names.
    * `files:read`, `files:write` — relay attachments in both directions.
    * `reactions:read`, `reactions:write` — reaction acknowledgements.
    * `assistant:write` — the app home surface.
  </Accordion>

  <Accordion title="Event subscriptions">
    Subscribe the bot to `message.channels`, `message.groups`, `message.im` and `message.mpim`. With Socket Mode there's no request URL to supply.

    You don't need `app_mention`. Switch spots a message that tags the app from the `message.*` events it already receives.
  </Accordion>

  <Accordion title="Socket Mode, interactivity and commands">
    Enable **Socket Mode** and **Interactivity**, and add the Switch slash commands listed in the manifest. Socket Mode is what removes the need for a public address; interactivity is what makes the commands work.
  </Accordion>
</AccordionGroup>
