Two Slack Apps Both Active in Same Channel . I Can't Remove One, Both Bots Responding

Questions
1

Hey everyone, need help untangling a Slack + n8n mess.
What happened:
I created two separate Slack apps, intending each for a different channel
Somehow both apps ended up integrated into the same channel
Now both bots respond when only one should
I can’t figure out how to remove one of the apps from that channel
My setup:
Two Slack apps, two OAuth credentials, two callback URLs
Two separate n8n workflows
Both apps currently active in the same channel
My questions:
How do I remove one Slack app from a specific channel without uninstalling it from the whole workspace?
Is there a way to restrict a Slack app to only one channel during setup?
Could the issue be that both apps are subscribed to the same workspace-level events instead of channel-specific ones?
Thanks in advance :folded_hands:

What is the error message (if any)?

Please share your workflow

(Select the nodes on your canvas and use the keyboard shortcuts CMD+C/CTRL+C and CMD+V/CTRL+V to copy and paste the workflow.)

Share the output returned by the last node

Information on your n8n setup

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

the tricky part with slack is that apps are workspace-level, not channel-level. both apps probably subscribed to the same workspace events, so they both see messages. few options: (1) in slack, you could try app management → find the unwanted app → there might be a ‘remove from workspace’ option but not ‘remove from channel’ (slack doesn’t really support that). (2) in n8n, add a filter node checking app_id or message author right after the trigger — that way only the right workflow processes it. (3) or if the apps have different tokens, maybe just disable one of the workflows instead? not sure if thats helpful but those are the angles i’d try

Hey thanks benjamin sold advices, I was also wondering do I need to create 2 apps for different type of workflows?

I have disable one of the workflows for now but thinking like just one app is enough for multiple workflows

hi @Asim_Arman
Slack apps are installed at the workspace level, not per channel, so I usually keep a single Slack app for multiple workflows and add filtering in n8n (channel ID, event type, user, bot ID, etc.) so only the intended workflow responds in each channel.

Thank you so much. I think I am going to go with this in the future, I have currently deacitvied the other flow, but will proceed with this, as I willbe working with multiple work flow in the future
