• SOAP is good for applications that require formal contracts between the API and consumer since it can enforce the use of formal contracts by using WSDL (Web Services Description Language).
• Additionally, SOAP has built in WS-Reliable messaging to increase security in asynchronous execution and processing.
• Finally, SOAP has built-in stateful operations. REST is naturally stateless, but SOAP is designed to support conversational state management.

Q) In Restful webservices, what are the methods and their use?
Ans -POST for CREATE, PUT for update, DELETE for deletion, GET for retrieval, PATCH for partial updates  and OPTION for checking before making a GET request

Reason- POST is idempotent as per HTTP specification and a creation request should be idempotent
PATCH is also idempotent
