REST API Meaning

A REST API (Representational State Transfer) is a standardized architectural style used to create web services that allow different software applications to communicate with each other. It relies on a stateless, client-server communication protocol, almost always HTTP.

In fintech, REST APIs are the primary way that third-party applications interact with banks, payment processors, and cryptocurrency exchanges to fetch data or execute commands.The architectural framework utilizes standard HTTP verbs-GET, POST, PUT, and DELETE-to manage resources, with data usually returned in a lightweight JSON format. Because the system is stateless, the server does not store any context about the client session; every request must contain all the necessary credentials and parameters to be processed.

This design makes the system highly scalable and allows developers to build robust integrations without needing to maintain complex persistent connections.For the crypto industry, REST APIs provided the first bridge between traditional web development and blockchain data. While they are excellent for historical data and account management, they are often supplemented by WebSockets for real-time needs.

Developers prefer REST for its simplicity and the fact that it doesn't require specialized libraries to implement, making it the universal language for integrating crypto payments into standard e-commerce websites.
