Since roughly the start of September 2026, our posts stopped being forwarded to Slack. The configuration was not changed at that time, and if I click the “Test” button, it creates the Slack message as intended. So the connection between Discourse and Slack is fine, it just does not create the messages when a new topic is posted. Was there an update at that time that could have broken our configuration? Or perhaps was there a change to how Chat Integrations should be used that I’m not aware of? Any help would be appreciated.

We found the issue: The account the chat integrations plugin was using for viewing posts was accidentally deleted during a cleanup.

Just in case, could you double-check if your Slack integration is currently using Granular Scopes? [תמונה]Set up Slack notifications using the discourse-chat-integration plugin Upgrading to ‘Granular Scopes’ If you set up your integration a while ago, you may need to upgrade to Slack’s “Granular Scopes” for things to work as described above. Instructions Go to Slack API: Applications | Slack and choose your Discourse integration app On the left, choose “Update to Granular Scopes” [Screenshot 2022-08-30 at 18.27.50] For “Bot Token Scopes”, select chat:write and chat:write.customize. If you’re using slash commands and/or transcript posting, also select users:read, channels:history, groups:history, im:history. You can unselect all other scopes. Click Next Uncheck all User Token scopes - we don’t need any of them Click Next, and complete the migration by clicking “Yes, Migrate my app” On the left, choose “Install App”, then “Reinstall to Workspace” Copy the “Bot User OAuth Token”, and paste it into the “chat_integration_slack_access_token” setting in Discourse In the Slack sidebar, under “Apps”, choose your Discourse integration. Click its name at the top, then “Add this app to a channel” Select all the channels which you want Discourse to integrate with Done :tada:

Hm, I’m not sure, but probably. Would that matter though? The test button within the chat integrations settings sends a message to Slack, so I don’t think this issue is coming from the Slack angle.

Hey there,

Do you see any errors associated to the chat integration in the /logs page?
