Representational State Transfer (REST) Meaning

In the broader context of software architecture, REST is a set of principles that ensure web services are scalable, fast, and easy to maintain. It treats every piece of information-like a user’s balance or a token's price-as a "Resource" that can be accessed via a unique URL.

This resource-based approach is what allows the entire modern internet to function as a cohesive system.A key principle of REST is HATEOAS (Hypermedia as the Engine of Application State). This means that a response from a REST server shouldn't just give you the data, but also links to "what you can do next," such as a link to transfer funds or view history.

This makes the API "Self-Discoverable," allowing developers to build complex integrations without needing to read thousands of pages of manual documentation.In fintech, REST is the industry standard for "Open Banking." Regulations like PSD2 in Europe require banks to provide REST APIs so that third-party apps can securely access a user’s financial data with their permission.

This has led to the rise of fintech aggregators like Plaid, which use REST to pull data from thousands of different banks and present it in a single, unified interface for the user.
