API endpoints Syncler-Glossar
An API endpoint is the specific URL or address through which an application or service can access the functions or data of an API (Application Programming Interface). The endpoint defines the location where a client (e.g. a middleware, an app, a web browser or a server) can interact with the API to send or receive information.
Basic concepts:
- API (Application Programming Interface): an API is an interface through which different software components can communicate with each other. APIs enable external applications to use certain functions or data of a system.
- endpoint: The endpoint is the access point to a specific function of the API. It is a combination of URL and HTTP method (GET, POST, PUT, DELETE, etc.) that defines how and where data is requested or sent.
HTTP methods and API endpoints:
An API endpoint often works in combination with an HTTP method that specifies what type of action is performed:
- GET: Requests data from an endpoint (e.g. retrieving a list of users).
- POST: Sends data to the server to create a new resource (e.g. create a new user).
- PUT: Updates existing data on the server (e.g. updating user data).
- DELETE: Deletes a resource on the server (e.g. deleting a user).
Why are API endpoints important?
- Modularity: Endpoints make it possible to break down certain functions and data into small, modular parts that can be accessed externally.
- Interoperability: Different applications and systems can communicate with each other via API endpoints without having to know the underlying implementation.
- Security: Endpoints can be protected with authentication mechanisms such as API keys or OAuth to ensure that only authorized clients can access them.
An API endpoint is therefore a key component of the communication between different software applications that enables access to specific functions or data of the API.
