While REST – or Representational State Transfer – can be used over nearly any protocol, when used for web APIs it typically takes advantage of HTTP.
Does REST API use HTTP?
HTTP is a contract, a communication protocol and REST is a concept, an architectural style which may use HTTP, FTP or other communication protocols but is widely used with HTTP. REST implies a series of constraints about how Server and Client should interact .
Who can interact with a REST API?
Under REST architecture, the client and server can only interact in one way: The client sends a request to the server, then the server sends a response back to the client. Servers cannot make requests and clients cannot respond — all interactions are initiated by the client.
What is the difference between API and URL?
A standard web API works the same way. The key difference between an ordinary URL and a URL that’s part of a web API is that an ordinary URL sends back something pretty designed to look good in your browser, whereas a web API URL sends back something ugly designed to be useful to a computer.

What is URL in REST API?

What is REST API vs SOAP?
REST: The key differences. SOAP is a protocol whereas REST is an architectural style. An API is designed to expose certain aspects of an application’s business logic on a server, and SOAP uses a service interface to do this while REST uses URIs.
