API Development involves designing, building, and implementing Application Programming Interfaces (APIs) that enable seamless communication and data exchange between different software systems. There are various types of APIs, including RESTful APIs, SOAP APIs, GraphQL, and WebSocket APIs, each serving specific purposes. API specifications, such as OpenAPI Specification (OAS) and GraphQL Schema Definition Language (SDL), define the structure and behavior of APIs. Documentation plays a crucial role in API development, providing clear instructions, examples, and troubleshooting guidance for developers who want to integrate with the API.
