Endpoint

Definition

In the context of APIs, an endpoint is one end of a communication channel. It refers to a specific URL where an API or a web service can be accessed by a client application.

Why It Matters

Endpoints are the "nouns" of an API. They define the specific resources that are available and how to access them. Well-designed endpoints are crucial for a clear and usable API.

Contextual Example

In a social media API, `/users/123/posts` would be an endpoint to retrieve all the posts for the user with ID 123. The client would make a GET request to this specific URL.

Common Misunderstandings

• The endpoint is the full URL, including the base URL of the service and the specific path to the resource.
• Different HTTP methods (GET, POST, DELETE) on the same endpoint URL perform different actions.
