Slack connections not working

I’m using a locally-hosted N8N on Render.com, and although every other part of my workflow is working - Absolutely none of the Slack connections are working. I just can’t seem to get the “Send message” node working, no matter the connection.

It looks like your topic is missing some important information. Could you provide the following if applicable.

  • n8n version:
  • Database (default: SQLite):
  • n8n EXECUTIONS_PROCESS setting (default: own, main):
  • Running n8n via (Docker, npm, n8n cloud, desktop app):
  • Operating system:

Hey @ruadhan_oc,

Welcome to the community :raised_hands:

What error are you seeing when you try and send a message? There could be something useful in the output.

I’m guessing you haven’t set up the Slack app properly and you are having connectivity/permissions issue. If that is so. Here are the basic (minimal) steps you could try (skip any steps that you have already done).

  1. Create app at Slack API: Applications | Slack
  2. Add bot token scopes (permissions):
    • chat:write
  3. Update Basic Information (optional)
    • Upload image (for example)
  4. Install the app to workspace
  5. Add the app to the Slack channel (from “Integrations” tab)
  6. Use bot token to connect the app

If that is all in place but still no message could be sent out, please, share the error message you get.
