Microsoft has ended the support for Basic authentication to interface with Business Central. It is mandatory to switch to OAuth 2.0.
OAuth is an open standard for authorizing access to web services and APIs from native clients and websites in Microsoft Entra ID.
More information about OAuth and why Microsoft is using this technique can be found at https://learn.microsoft.com/en-us/dynamics365/business-central/dev-itpro/webservices/authenticate-web-services-using-oauth
This Knowledge Base contains a step-by-step plan to implement the configuration in the Azure Admin Portal and Business Central and eventually test it using Postman. Testing in Postman consists of two parts; requesting the Access Token and testing a web service using the obtained Access Token.
