Hey everyone,
I run a large Slack community and have a Zap set up to automatically send a Direct Message to new joiners.
Everything worked fine before, but recently the Slack step keeps failing with this error:
Error from Slack: channel_not_found
Here’s what I’ve already checked:
-
The Slack connection is active
-
The user definitely exists and can be DMed manually
-
I’ve tried both @username and the user ID format
-
Reconnected the Slack app in Zapier
Still no luck — the Zap keeps erroring out.
Has anyone else run into this issue recently, or know if something changed in how Zapier handles Slack DMs?
Would love to hear if there’s a workaround or updated setup (permissions, scopes, or using Slack IDs differently).
Thanks!
Daniel
