- A REST resource enables access to data,…but doesn't in itself do anything with that data.…To use a REST resource, we have to pass along instructions…about what action we want to perform.…This is done using HTTP methods, also called verbs.…Anytime you use a web browser,…you or rather the browser use HTTP methods…to tell the server at the other end of the URL…what type of request is being sent.…By far the most common of these methods is Get…which literally means get what's at the end…of this address and send it to me.…
Anytime you visit a webpage or follow a link…or click reload or forward or back…or any other standard interaction in a browser,…you are sending a get request over HTTP.…The same goes for REST APIs.…If you want to retrieve the data of a resource,…you send a Get request.…This request will either return a 200 OK HTTP status…along with the requested data or a 404 Not Found HTTP status…if there's nothing at the other end of the resource…or the resource is invalid.…
Yes, that is the same 404 Not Found error…
