API
An API is a formalized set of rules and protocols that enables different software applications to communicate and exchange data programmatically. It defines the methods, request/response structures, and data formats (like REST/GraphQL) that one service can use to request services or resources from another. It is the contract and abstraction layer that exposes specific functionality while hiding the underlying implementation details.
Components of an API
API Types and Protocols
-
REST APIs: Most common modern API type using standard HTTP methods (GET, POST, PUT, DELETE) and stateless communication
-
SOAP APIs: More structured protocol using XML for message format, common in enterprise systems
-
GraphQL APIs: Allows clients to request only the specific data they need, reducing over-fetching
-
JSON-RPC/XML-RPC: Remote procedure call protocols for executing code on remote system
