Connecting Your AI Agent to Slack and Telegram With Cortex

Your AI agent is only as useful as it is accessible. If your team is already working in Slack or Telegram, why force them to jump to a separate web portal to interact with your agent? Cortex makes it dead simple to deploy your agent directly into the channels where your team already communicates.

Why Channel-Native Agents Beat Web-Only Chatbots

There's a fundamental difference between deploying an agent to a web interface and deploying it directly into the tools your team uses every day.

A web-only chatbot requires context switching. Someone on your team sees a problem in Slack, but to get help from your agent, they have to:

  • Navigate to a new browser tab
  • Load a different interface
  • Explain the problem again
  • Switch back to Slack to share the result

A channel-native agent eliminates all of that friction. Your agent lives right there in the conversation. Team members interact with it using the same affordances they already know; no new logins, no new interfaces, no training required.

This isn't just about convenience. Agents that live in team channels actually understand context better. They see the conversation thread, the people involved, the reactions and follow-ups. They can participate naturally in the flow of work rather than operating in isolation.

Slack Integration: OAuth and Instant Setup

Setting up your Cortex agent in Slack takes about five minutes.

During the Cortex onboarding flow, you'll connect your agent to Slack via OAuth. This is the same OAuth standard that powers integrations across thousands of apps, so it's secure and standardized.

Here's what happens:

  1. You click "Add Slack" during agent setup
  2. You're redirected to Slack's authorization screen
  3. You select which workspace and channel your agent should join
  4. You approve the scopes (which are minimal: read messages, send messages, access user info for context)
  5. Cortex receives the OAuth token and securely stores it
  6. Your agent appears in Slack immediately

Once live, your agent can:

  • Respond to mentions in any channel it's invited to
  • Participate in threads
  • React to messages
  • Use Slack's formatting (bold, code blocks, attachments)
  • Access user context (names, roles, departments) if your workspace has that data

The agent runs on its dedicated Ubuntu server within the Cortex infrastructure, so it can respond in milliseconds. No polling, no delays; Slack sends webhooks directly to your agent.

Telegram Integration: BotFather and Speed

Telegram offers a different philosophy; less centralized, more direct. Setting up a Cortex agent on Telegram is even faster than Slack.

During onboarding, you'll work with Telegram's BotFather bot:

  1. You open Telegram and search for @BotFather
  2. You follow BotFather's prompts to create a new bot
  3. BotFather gives you an API token
  4. You paste that token into Cortex during agent setup
  5. Your agent is live in seconds

Telegram bots can be added to groups or used for one-on-one conversations. They can:

  • Respond to text and voice messages
  • Send rich messages with inline buttons
  • Handle callback queries from button presses
  • Work completely independently of any other platform (which appeals to distributed teams)

One advantage of Telegram: it's ubiquitous. If your team is already using Telegram for real-time communication, your agent can be there without relying on Slack's enterprise infrastructure.

WhatsApp and iMessage: Coming Soon

The Cortex roadmap includes WhatsApp and iMessage integrations. These will follow the same principle: native channel deployment with zero friction for your team.

WhatsApp will use the WhatsApp Business API, which is ideal for teams that prefer WhatsApp's encryption and mobile-first design. iMessage support will allow Mac-centric teams to interact with agents directly from their devices.

Both integrations are in active development and will roll out to all Cortex tiers when ready.

How Cortex Keeps Your Integrations Secure

One thing teams worry about is security. When you give an app access to Slack or Telegram, you're granting it the ability to see and send messages. Cortex treats this trust seriously.

All OAuth tokens are encrypted at rest using keys you own (BYOK for Enterprise customers). Tokens are never logged, never exposed in debugging output, never sent to third parties. Each token is scoped to the minimum permissions needed: your Slack agent only gets the ability to read and send messages in the channels it's invited to.

For Telegram, the bot token is treated the same way; encrypted, scoped, audited.

Getting Started

To add Slack or Telegram to an existing Cortex agent:

  1. Log in to your Cortex dashboard
  2. Select your agent
  3. Go to Settings > Channels
  4. Click "Add Channel"
  5. Choose Slack or Telegram
  6. Follow the OAuth or BotFather flow
  7. Confirm and test

Your agent will immediately start responding in your channels. You can add multiple channels (one Slack workspace, multiple Telegram groups, etc.) to a single agent, and it will maintain consistent behavior across all of them.

The Future of Team-Centric AI

Cortex's philosophy is straightforward: your agent should meet your team where they already work. No context switching, no separate portals, no friction.

As we add WhatsApp and iMessage, this philosophy stays the same. Every integration is designed to make your agent a native participant in your team's communication, not an external tool you have to manage.
