- The Microsoft Dynamics 365 Web API is a RESTful service built on OData v4, enabling developers to interact with Dynamics 365 CRM and ERP data using standard HTTP methods.
- All modern implementations should use API version v9.2 (e.g., /api/data/v9.2/).
- Authentication requires registering an application in Microsoft Entra ID (formerly Azure Active Directory) and obtaining an OAuth 2.0 access token before making any API calls.
