APIs (Part 1)

Here are a few points you must know:

• All Web Services are APIs, but not all APIs are Web services.
• APIs are application interfaces, meaning that one application is able to interact with another application in a standardized way.
• Web services are a type of API, which must be accessed through a network connection.
• REST APIs are a standardized architecture for building web APIs using HTTP methods.
• Web service is a collection of open source protocols and standards used for exchanging data between systems or applications whereas API is a software interface that allows two applications to interact with each other without any user involvement.
• Web service is used for REST, SOAP and XML-RPC for communication while API is used for any style of communication.
• Web service supports only HTTP protocol whereas API supports HTTP/HTTPS protocol.
• Web service supports XML while API supports XML and JSON.
• All Web services are APIs but all APIs are not web services.

GET - Path/Query params are provided to get response
PUT - Header, Body and Query params are provided to get the response
PATCH - Is used for updating without providing payload and only thing that needs to be updated
POST - Header, Body and Query params are provided to get the response
DELETE - Header, Body and Query params are provided to get the response
