# Build with KongAir

Follow these guides to understand the API contracts, request the right access, and keep development and production credentials separate.

## [Start here](#start-here)

-   [Getting started](https://dev.kong-air.com/guides/getting-started): choose an API and find its contract.
-   [Application access](https://dev.kong-air.com/guides/application-access): register an application, request approval, and use a Portal-issued API key.
-   [Environments and versions](https://dev.kong-air.com/guides/environments): understand which contract you are reading and where your credentials work.

## [Before you integrate](#before-you-integrate)

KongAir is a reference implementation, not a commercial airline service. Use fictional data and never submit real passenger or payment information.
