REST API basics tutorials with examples
REST is one of the popular web services in the software world. REST is abbreviated as Representational State Transfer. REST API used to develop HTTP-based web services
REST is similar to SOAP web services, SOAP web services can be accessed using objects and methods, whereas REST can be accessed using URLs with HTTP operations like GET, POST, DELETE, and PUT.
REST API is used to write the API for web applications to access the services. REST API is a protocol, that can be developed and consumed in many languages like Java, .net

Usually, different uses deal with REST API.
Producer:- users create a RESTfull service and host this service and expose this service to the outside world with URL
www.myorg.com/service/get. This can be developed in any language.
- Consumer:- Consumer is an actual user who accesses the REST web service. users code in any language to consume the web service by HTTP communication

- Design and develop and consume is platform-independent
Disadvantages of REST API:
- Not be used for complex message distributed systems.
- security mechanism has to be implemented on its own, no standard protocol for security
- Used only for HTTP-based communication
