Getting Started with Garage Hive APIs

Garage Hive has a wide range of API capabilities. There are standard Microsoft Business Central APIs available to all users, as well as Garage Hive-built endpoints — some available to everyone, and some exclusive to  Garage Link Advanced Plus⁠ .
For a comprehensive guide to how Business Central integrations work — including web services, authentication, and integration scenarios — see Microsoft's official documentation:  Integration overview for Business Central .

Authentication

All Garage Hive APIs require authentication through Microsoft Entra ID (formerly Azure Active Directory). Developers must use the client's Entra ID tenant to obtain an access token, which is then included as a Bearer token in the header of every API request. For full details on how Business Central API authentication works, see the  Microsoft Learn documentation .
