We want to inform users when there is a problem with their webhooks (especially problems that cause webhooks to be disabled). To make this possible we could: - Allow users to register ways to notify them of these problems, including - email - slack (assumes use of slack integration) - or other chat integration - SMS message - Create incident/issue with custom template - Send messages to these channels if the webhook changes state optionally, allow this to be configured to use a project or group's default notification settings (using cascading settings to propagate values)
