Endpoint

An endpoint is a specific URL or address where an API (Application Programming Interface) receives and processes requests. It serves as a communication gateway between clients (such as web or mobile applications) and a server, enabling data exchange and interaction with a service. Each endpoint is associated with a particular resource or function, such as retrieving user information or submitting a form.

Also known as : API endpoint, service endpoint.

Comparisons

• Endpoint vs. API : An API is a collection of rules for interacting with a system, while an endpoint is a specific URL within that API.

• Public vs. Private Endpoints : Public endpoints are accessible to external users, while private endpoints are restricted within an organization's network.

Pros

• Structured communication : Provides a clear and organized way for clients to interact with a system.

• Scalability : Allows services to be modular and distributed across multiple endpoints.

• Security control : Can enforce authentication and authorization mechanisms.

Cons

• Potential latency : Multiple requests to different endpoints may slow down performance.

• Security risks : Unsecured endpoints can expose sensitive data to unauthorized users.

• Versioning challenges : Updating or modifying endpoints may require backward compatibility management.

Example

A weather application requests current temperature data from an API endpoint:

GET https://api.weather.com/v1/current?city=NewYork&unit=celsius

In this request:

https://api.weather.com/v1/current is the endpoint.

Query parameters (city=NewYork&unit=celsius) specify the location and temperature unit.

The API responds with weather data, enabling the app to display real-time conditions.
