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 API’s 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.

· Controller

· Routing

· Models

· Middleware

· Dependency injection

In web API we can Implement authentication and authorization functionality to secure the web API’s. 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 API’s and In swagger we can describe the API’s details and also as per the requirement we can create custom swagger page to describe the API’s details.

Using the different types of test cases framework like Nunit, Xunit, MSTest developer can easily test the web API’s.
