Help Scout's Mailbox API, Docs API, Beacon JavaScript, Apps, and Open Source Tools

Help Scout offers many integrations right out of the box, but there are lots of other apps out there in the world that you might want to connect — maybe even some your team has built for yourselves.

The Mailbox API, custom apps, and open source tools are available for you to link your Help Scout account to any number of other apps or access your data for any number of other reasons. Leveraging these tools will require some developer skill in most instances, but if you can dream it, point your developers over to the documentation to see if they can build it!
