REST APIs
What is a REST API?
REST API stands for Representational State Transfer Application
Programming Interface. It is a set of rules and conventions for building and interacting with web services. REST APIs allow different software applications to communicate with each other over the internet, using standard HTTP methods.
Key Concepts
- Statelessness: Each API call from a client
to the server must contain all the information needed to understand and process the request. The server does not store client context between requests, making REST APIs scalable and efficient.
- Resources: In REST, resources are represented by URLs (Uniform Resource Locators). Each resource can be manipulated using standard HTTP methods, such as:
- GET: Retrieve data from the server.
- POST: Send data to the server to create a new resource.
- PUT: Update an existing resource on the server.
- DELETE: Remove a resource from the server.
- Representations: Resources can be represented in various formats, typically JSON (JavaScript Object Notation) or XML
(eXtensible Markup Language). The representation conveys the state of the resource and can be modified by the client.
- Client-Server Architecture: REST APIs follow a client-server model where the client (such as a web or mobile application) interacts with the server. This separation allows for a more flexible and scalable architecture.
- Hypermedia as the Engine of Application State (HATEOAS): REST APIs can provide hyperlinks to related resources in their responses, allowing clients
to navigate the API dynamically.
