API Design Interview Question

What is an API endpoint?

Updated 2026-07-10 · Beginner friendly
Quick answer

An endpoint is a specific URL where an API receives requests for a particular resource or action. For example, /users is an endpoint for working with users. Combined with an HTTP method, an endpoint defines one operation, so GET /users lists users and POST /users creates one. Each endpoint is a doorway into the API.

How endpoints are named

Good REST endpoints use nouns for resources, not verbs, because the HTTP method already carries the action. So you use /orders rather than /getOrders, and let GET, POST, and DELETE decide what happens.

In the interview

Say endpoints should use nouns, not verbs, in REST. Correcting a verb style path like /createUser to POST /users during an interview is a small detail that signals solid API design habits.
