How you uninstall Matter from Slack depends on whether you want to keep the Slack channel: delete the channel and Matter goes with it, or keep the channel and remove only Matter from the web app. Either way, you are removing the web app workspace Matter created and connected to your channel when it was installed.
Who can use this: The Workspace Owner on every plan (on Enterprise Grid, Workspace Owners and Channel Admins). Slack only. Using Microsoft Teams? See How to uninstall Matter from Microsoft Teams.
For an overview of the whole feature, read the Matter setup and rollout guide for Slack.
Before you uninstall
Billing stops. Removing Matter cancels your paid subscription straight away and you are not billed again; there is no separate cancellation step. Enterprise contracts are handled through your account contact. If you only want to stop paying but keep your history, use the cancellation form and move to the Free plan instead. How to cancel or downgrade Matter subscription
Your team loses access to its history. Uninstalling closes the Matter workspace, so your team will no longer see its kudos, celebrations, coin balances, or pending reward requests. Approve or decline pending requests and export your reports first if you want a record. If you only want fewer messages rather than no Matter at all, see Stop or reduce the messages Matter sends before uninstalling. Analytics report export
Moving rather than leaving? To keep Matter but use a different channel, transfer it. To move between Slack and Microsoft Teams, Matter can migrate your workspace with its history. Too many messages? Each one can be turned off in Settings without removing Matter. Transfer Matter to a new channel in Slack and Migrating Matter between Slack and Microsoft Teams
