Slack

💬 Slack Connector

Send messages, read channel history, and fetch workspace users or channels directly inside your workflows.

The Slack Connector allows your workflows to interact with your Slack workspace — letting you send messages, read recent conversations, fetch channels, retrieve users, and more.

Use it to automate notifications, collect inputs from Slack, or build powerful human-in-the-loop workflows.

🧠 How It Works

When you drop the Slack node into a workflow:

1. The node authenticates using a selected Slack credential.
2. You enable operations such as sending a message or reading channels.
3. Slack’s API is called via your backend.
4. The response (channels, messages, users, etc.) is passed to the next workflow node.

This makes Slack a powerful input/output tool in your automation canvas.

• Search by provider or workspace
• Or add a new connection

The credential determines which Slack workspace and permissions the node has access to.

Each operation maps directly to a capability in your backend Slack integration.
