APIs (Application Programming Interfaces) are essential to modern digital development, enabling smooth data exchange between applications. Whether you’re building a custom web platform or a full-scale mobile app, understanding APIs is key to crafting efficient and scalable solutions. This in-depth guide by HT Business Group covers different API types, their applications, licensing, technologies, pros and cons, along with a helpful comparison table and FAQs.
What is an API?
An API, or Application Programming Interface, acts as a bridge that lets software programs interact. Think of it as a waiter taking orders and delivering meals from the kitchen — the API handles the request and returns a response.
Whether integrating third-party systems like payment gateways or developing robust internal systems, APIs simplify communication and improve performance.
