Why is REST API useful?
One of the key advantages of REST APIs is that they provide a great deal of flexibility. Data is not tied to resources or methods, so REST can handle multiple types of calls, return different data formats and even change structurally with the correct implementation of hypermedia.
Why is rest more popular than soap?
Benefits of REST Over SOAP REST allows a greater variety of data formats, whereas SOAP only allows XML. Coupled with JSON (which typically works better with data and offers faster parsing), REST is generally considered easier to work with. REST is generally faster and uses less bandwidth.
Is GraphQL a REST API?
GraphQL follows the same set of constraints as REST APIs, but it organizes data into a graph using one interface. Each object is then backed by a resolver that accesses the server’s data.
Is SOAP Web Services Dead?
SOAP is a W3C standard and it’s used as information exchange format in W3C web services.

Why rest is lighter than soap?
SOAP is XML only, while REST allows you to send any payload, such as JSON which is less verbose and simpler than XML. Generally speaking, it takes less memory and less bandwidth to deal with JSON than XML. On another level, using SOAP you typically describe everything as services.
Why is soap still used?
SOAP is still used in many big organisations. With built-in security and reliability functions, SOAP is a great choice for applications where security is more critical than performance. SOAP is highly extensible.

2 Answers. Basically Stateful means that server stores information about the client and uses that information over a series of requests. So performing one request is dependant upon the state of some other request (e.g. previous). Implementing this is possible with http protocols.

SOAP needs more bandwidth for its usage whereas REST doesn’t need much bandwidth.
