# Slack Integration

> Connect Slack so Dume can post messages and see your channels and workspace members.

## Overview

Connect Slack so Dume can post messages to a channel on your behalf and look up channels and workspace members.

<Warning>
  This integration is newer than the others and still expanding. Reading and summarizing existing message history isn't part of it yet, only posting and directory lookups. If a request needs Dume to read past Slack messages, it may not work today.
</Warning>

## 1. Connect (OAuth)

<Steps>
  <Step title="Open Integrations">Go to **Integrations**.</Step>
  <Step title="Authenticate">Click **Connect Integration** on the Slack card and authorize your workspace.</Step>
  <Step title="Test">Ask: "What Slack channels am I in?"</Step>
</Steps>

<Tip>Revoke anytime from Slack's own **Apps and integrations** settings, or disconnect from Dume's Integrations page.</Tip>

## 2. What it can do today

* List channels you're a member of
* Look up workspace members
* Post a message to a channel

## 3. Quick commands

```
What Slack channels am I in?
Post to #marketing: Launch is live
Who's in the #eng-standup channel?
```

## 4. Troubleshooting

| Issue               | Fix                                                           |
| ------------------- | ------------------------------------------------------------- |
| Channel not found   | Confirm you're a member of the channel and use its exact name |
| Permission error    | Reconnect and approve the requested workspace scopes          |
| Message didn't post | Check that Dume has posting permission in that channel        |

## 5. Security

* OAuth tokens only, no passwords stored
* Scoped to the workspace you authorize
* Revocable anytime
* Posting a message asks for confirmation first

<Note>
  Slack is a data integration, not a messaging channel. To reach Dume from outside the app, use [WhatsApp](/interfaces/whatsapp) or [phone](/interfaces/phone) instead.
