Summary

Subho Halder, co-founder and chief information security officer at Appknox, explores the increasing reliance on APIs due to the rapid expansion of application functionalities and microservices. APIs, acting as intermediaries, enable seamless communication between dependent applications and come in various types like REST, SOAP, GraphQL, XML-RPC, and WebSocket, each with distinct features and advantages. REST-based APIs are highlighted for their simplicity and scalability, making them suitable for beginners, while SOAP-based APIs are noted for their complexity and enhanced security. GraphQL offers advanced query capabilities, and XML-RPC provides ease of use with minimal bandwidth, whereas WebSocket facilitates interactive communication without server polling. APIs are now integral to modern applications, accelerating development, enhancing business value, and reducing time-to-market, indicating a promising future for API-centered development.
