The most preferred approach nowadays to secure the web api resources is by authenticating the users in web api server by using the signed token (which contains enough information to identify a particular user) which needs to be sent to the server by the client with each and every request. this is called the token-based authentication approach., create an api service the token service will help you get an access token from the authorization server, but then you need to call the api with your newly minted token. follow the same pattern as the token service by creating an iapiservice interface and a simpleapiservice implementation class for it. the complete interface looks like:.

Once authenticated, a security token is generated and stored on the server and is returned to the client. the client will then pass this token to the api in order to access restricted endpoints...., download dbscripts.zip - 1.8 kb; download music api store - 32 mb; in modern era of development we use web api for various purpose for sharing data, or for binding grid, drop-down list, and other controls, but if we do not secure this api then other people who are going access your web application or service can misuse it in some or other way and also we are into era of client-side framework ....
