One great use of Github is as an API issue management tool. The Github issue management system allows you to easily accept issue reports from your API community and apply labels to organize them into appropriate categories, for processing by your development team.
To setup Github Issue Management for your API, just create a new repository, but you won't actually being pushing any code, you will just be using it as a container for running issue management. Think of it as repository for your API itself.
Once setup, you can link the issue management page directly from your API area, allowing users to actively submit issues, comment and potentially be part of the API product development cycle.
