What does REST mean in software engineering?

REST stands for Representational State Transfer. It is an architectural style for designing web APIs that use HTTP methods and resource-based URLs. Instead of calling specific functions, REST APIs let you interact with resources using standard HTTP verbs like GET, POST, PUT, and DELETE.

How do you use REST in a sentence at work?

You can say things like: Our team is building a REST API for the mobile app, or This endpoint does not follow REST principles. You can also use the adjective RESTful, as in We need a RESTful service for this integration.

Is REST formal or informal?

REST is neutral in formality. You use it in technical discussions, code reviews, and meetings with the same professional tone. It is a standard term across all tech environments, from startups to large corporations.

What is the difference between REST and SOAP?

REST is a lightweight, stateless architectural style that uses standard HTTP methods and is easier to work with for most web applications. SOAP is a more complex protocol with strict messaging rules and is heavier to implement, though it offers more advanced features for enterprise systems.

Why is REST important for developers?

REST is important because it provides a standard, predictable way to design APIs. This makes it easier for teams to collaborate, for other developers to understand your code, and for different services to communicate reliably. Most modern web development relies on REST principles.

Say it like this

✓REST principles

✓RESTful web service

✓REST endpoint

✓REST architecture

Real examples

in a standup

"We are refactoring our microservices to follow strict REST standards for better consistency."

in a code review

"This endpoint violates REST conventions because it uses POST to retrieve data instead of GET."

in a team meeting

"Our new API design uses REST principles, which makes it easier for mobile teams to integrate."

Don't say this

Handle with care. REST is an architectural style, not a protocol. Do not confuse it with HTTP or JSON. Also, REST is never capitalized as Rest unless starting a sentence.

✕We are using REST protocol to communicate with the server.

✓We are using REST architecture with HTTP protocol to communicate with the server.— REST is not a protocol but an architectural style. HTTP is the protocol.

✕Our API is not fully rest because we use custom endpoints.

✓Our API is not fully RESTful because we use custom endpoints.— The adjective form is RESTful, not rest. REST should always be capitalized as an acronym.

✕We need to rest our database before deploying.

✓We need to test our database before deploying.— In this context, you mean test, not REST. REST and test are different words with different meanings.
