Endpoint

A specific URL in an API that performs a defined action. For example, POST /api/users creates a user; GET /api/users/123 fetches user 123.

Endpoints are the building blocks of APIs. Understanding endpoint structure helps you read API documentation, test integrations, and communicate precisely with developers.

A founder reads the Stripe API docs and finds the endpoint POST /v1/customers. She asks her developer to call this to create a customer record on signup.
