How to Register Business Central App with API Permissions in Azure Portal

Registering the Business Central application on Azure is required when configuring OAuth authentication. Follow the below steps to register D365 BC app in the Azure portal.

Log in to the Azure Portal and select “App registrations” under Azure services.
Click on the “New registration” button:
On the “Register an application” page enter the following details and click on the “Register” button:
- Name (Name of your application).
- Supported account types:
  select “Accounts in any organizational directory (Any Azure AD directory – Multitenant)” if you want to allow access to your app from any Azure AD tenant, or “Accounts in this organizational directory only (Single tenant)” if you want to limit access to your app to a specific Azure AD tenant.
- Redirect URI (optional):
  Select “Web” and enter the redirect URL for your BC app. This is the URL where your app will receive the authentication response. I add the URL as: https://businesscentral.dynamics.com/ for the BC cloud version.
Under “Certificates & secrets” click the “New client secret” button to create a new secret:
Enter a description for the secret, select an expiration period, and click the “Add” button:
Note down the value of the client secret, as you will need it later and it is visible only for the first time:
