These integrations are set up once per organization, and are then usable in all projects.
Issue tracking allows you to create issues from within Sentry, and link Sentry issues to existing supported integration Issues.
Once you’ve navigated to a specific issue, you’ll find the Linked Issues section on the right hand panel. Here, you’ll be able to create or link issues.
Alert notifications in Sentry can be routed to many supported integrations, but by default are aimed at email. You will need to configure a project’s Alert Rules to properly route notifications to a specific integration.
