Build a Slack Bot with n8n in 15 Minutes

Prerequisites

• Slack workspace + Bot token with chat:write and channels:history
• n8n account/self-hosted instance

Steps

1. Create Slack App, enable necessary scopes, install to workspace.
2. In n8n, configure Slack credentials with the Bot token.
3. Add a Slack Trigger (events) or Poll node for channel messages.
4. Filter messages and route with Switch/If nodes.
5. Reply using Slack > Post Message. Deploy the workflow.

Enhance with slash commands, OpenAI nodes, or persistence for conversation threads.

Security: store tokens as credentials; avoid hardcoding secrets.
