Hi, @KumarPeriyasamy-4226,
Web API
access can be protected to avoid unauthorized access. In this article I would like to present how to configure Azure Active Directory B2C (Business-to-Consumer). Before that its worth to mention few words about Azure AD (Azure AD).
Azure Active Directory
is a cloud identity provider service or Identity as a Service (IdaaS) provided by Microsoft.
Azure AD B2C
is a separate service (with same technology as standard Azure AD) which allows organizations to build a cloud identity directory for their customers.
Here is a article of How to configure Azure Active Directory B2C and integrate authentication in ASP .NET Core Web API project. See Azure AD B2C and ASP .NET Core Web API.
