Getting Started with Garage Hive APIs

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 and Business Central APIs require authentication through Microsoft Entra ID (formerly Azure Active Directory). Before making any API calls, you must obtain an access token by sending a POST request to the Microsoft identity platform token endpoint:
POST https://login.microsoftonline.com/{{tenantId}}/oauth2/v2.0/token
Replace {{tenantId}} with the client's Microsoft Entra ID tenant ID. The returned access token must then be included as a Bearer token in the Authorisation header of every API request.
Note: Authentication is handled entirely by Microsoft. For full details on the required parameters, grant types, and scopes, see  Authenticating Business Central Web Services using OAuth  on Microsoft Learn.
