Mastering API Authentication in Business Central: Basic and OAuth Explained.

Hi Readers,

In continuation to the API Series today we will discuss about authentication types for Business Central API's on-prem and online.

Mastering API authentication in Business Central involves understanding basic and OAuth methods. Basic authentication is deprecated for online environments, while OAuth is essential for cloud use. The process includes setting up app registrations in Azure, defining permissions, and generating access keys to facilitate secure API interactions.

  • Different types of authentications for Business Central APIs are crucial for secure access. Understanding the variations between OAuth and basic authentication can enhance API usage efficiency.
  • Basic authentication for accessing APIs involves generating a web service access key and registering applications in Azure. This process ensures secure access to resources in both on-premises and cloud environments. As of today, Basic Authentication only works with Business central on premises environments.
  • Setting up an application in Azure AD requires defining permissions to ensure it can access Business Central effectively. This includes selecting application or delegated permissions based on the app's needs.
  • The process of setting up API permissions requires careful attention, especially when permissions are not automatically granted. Understanding the role of administrators in this context is crucial for effective management.
  • The process of registering an application in Business Central is crucial for managing API permissions. This involves setting a client ID, username, and defining user roles effectively.
  • The administrator grants API permissions by reviewing the access rights requested by the application. This consent process ensures that the necessary data can be accessed securely.
  • Understanding the different types of authentications available is crucial for effective API integration. OAuth is emphasized as the standard for Business Central SAS, while Basic Authentication is also discussed.
