# Incode General Reference

This section answers quick, standalone questions that come up across integrations: what Incode supports, what a code or status means, and how a session or session type behaves. It's built for both developers and business users, and it's meant to be searched rather than read start to finish. For deeper implementation detail, see the Helpful Links below.

## Coverage and Compatibility
