Introduction of Web API
API Stands for Application Programing Interface. It allows to communicate with different services with each other over the Internet.
Advantage of Web API
Using ASP.Net core web APIโs framework, Developer can build Restful web service and it provide many features.
HTTP client can mostly be used in web API so that different types of HTTP methods like GET, POST, PUT, DELETE and other different types of operations can be perform.
In Web API we have different types of components.
ยท Controller
ยท Routing
ยท Models
ยท Middleware
ยท Dependency injection
In web API we can Implement authentication and authorization functionality to secure the web APIโs. Using the client Keys and token we can verify the identity and allows user to access the specific endpoints.
Using Swagger and Postman tools developer can easily test the APIโs and In swagger we can describe the APIโs details and also as per the requirement we can create custom swagger page to describe the APIโs details.
Using the different types of test cases framework like Nunit, Xunit, MSTest developer can easily test the web APIโs.
