How do I remove an integration to a source control tool?

Go to the "Your company account" tab in the settings and find the source control integration that you would like to remove. Open the popup dialog for the integration and click "Delete".

When you delete a source control integration, this will immediately cause all future commits that use this integration to be ignored by Scrumwise. So, this is a secure way to revoke an integration and its associated webhook URL, even if you do not remove the webhook URL from the source control tool (but it's a good idea to do that anyway, of course).
