Learn what REST API is, how it works, its benefits, architecture, integrations, best practices, and why it powers modern apps, AI, and cloud solutions.
What is REST API?
A REST API, or Representational State Transfer, is a software architecture type that facilitates seamless communication between applications over the web. To demonstrate what a REST API is with an example: when you check the weather in a mobile app, the mobile app requests data from a server by applying REST principles and then displays the data typically in a JSON format.
How Does a REST API Work?
A REST API is designed so that two systems can easily communicate with each other over the web by establishing some simple rules. A REST API is designed using the request and response model. The request and response schema allows applications to exchange data with one another efficiently by establishing endpoints, as well as standard HTTP methods that facilitate and define the interactions.
SOAP API vs REST API: Which One Should You Use in 2025?
From comparing SOAP API vs REST API within the context of your individual and specific application’s context, while both methods provide a way for two systems to communicate with one another, they differ in relation to flexibility, scalability, and performance, and understanding these differences can aid in determining which method would be best for your specific application.
