Basecamp API Resource Type

I am looking to setup a Basecamp API Resource, but cannot find the Basecamp API Resource type. I see documentation about this at Basecamp 3 Integration, but when I add a resource, Basecamp API is not an option. Am I missing something obvious?

Hello @jpangborn,

The documentation is outdated and we are looking at removing this from our site.

You should be able to connect to Basecamp using the Basecamp API
