Slack

In one line: Connect Slack so your UnleashX agent can send and read messages, browse channels and users, share and find files, and set reminders — all in your workspace.

​
1. Overview

Slack is the messaging platform where your team chats, shares files, and coordinates work across channels and direct messages. It is the day-to-day communication hub for most organizations. Once you connect Slack to UnleashX, your agent can post messages to channels and DMs, read recent conversation history, search across messages, list channels and users, upload and fetch files, and create reminders — without you switching apps. Connecting Slack to UnleashX turns your agent into a hands-on teammate: it can announce results, summarize a channel, pull a file someone shared, or nudge a colleague with a reminder — driven entirely by natural language.

​
2. What you’ll need

  • A Slack account with access to the workspace you want to connect.
  • Permission to authorize apps for that workspace. Some workspaces require an admin or Owner to approve new app installations.
  • The channels you care about should exist (the agent can post to public channels it can join; for private channels the app must be invited).
If you are not a workspace admin, you may see an “approval required” screen during authorization. Ask a workspace Owner/Admin to approve the UnleashX app, then retry.

​
3. Get your credentials

Slack uses OAuth, so you don’t copy a long-lived secret by hand — you click through Slack’s authorization screen and Slack hands UnleashX an access token. The steps below happen automatically during Connect on UnleashX (Section 4); this section explains what you are approving.
1

Start the connection from UnleashX

When you click Connect on the Slack connector (Section 4), UnleashX redirects you to Slack’s official authorization page at https://slack.com/oauth/v2/authorize.
2

Pick your workspace

At the top right of the Slack screen, confirm the workspace you want UnleashX to act in. Switch it if needed.
3

Review the requested scopes and click Allow

Slack shows exactly what the app can do. Click Allow to grant access. Slack then returns an access token to UnleashX automatically — you never see or paste it.
The access token is stored securely by UnleashX. You do not manage it manually. To stop access later, disconnect in UnleashX or revoke the app from Slack → Settings & administration → Manage apps.

  • Read recent message history and thread replies.
  • Search messages, list channels and users, and read workspace info.
  • Upload, fetch, and delete files; create reminders.
UnleashX CANNOT:

​
9. Frequently asked questions

Is my Slack data stored by UnleashX? UnleashX reads messages and files on demand to fulfill your requests. It keeps lightweight snapshots for “new message / new user / new channel” triggers so it can detect what changed; these are tied to your session and cleared when the session ends. Can multiple team members connect Slack? Yes. Each user authorizes their own workspace access, and the agent acts with the permissions granted by whoever connected. How do I rotate or revoke access? Disconnect in UnleashX or remove the UnleashX app from Slack → Manage apps. Reconnecting issues a fresh token automatically. Why can’t the agent read a private channel? Slack requires the app to be a member of private channels. Invite the UnleashX app to the channel, then try again.
