The abbreviation REST stands for "REpresentational State Transfer".
REST APIs are used to call resources and allow the software to communicate based on standardized principles, properties, and constraints.

๐ Working of REST APIs
REST APIs operate on a simple request/response system. You can send a request using these HTTP methods:
๐น GET
๐น POST
๐น PUT
๐น PATCH
๐น DELETE
Also, REST APIs can include endpoints, headers, URL parameters, and the request body.

Also, REST APIs can include endpoints, headers, URL parameters, and the request body.
The endpoint (or route) is the URL you request for. The path determines the resource youโre requesting for. Think of it like an automated answering machine that asks you to press 1 for service, press 2 for another service, 3 for yet another service, and so on.
When you send a request to an endpoint, it responds with the relevant data, which is generally formatted as JSON, XML, plain text, images, HTML, and more.
REST APIs can also be designed with many different endpoints that return different types of data. Accessing multiple endpoints with a REST API requires multiple API calls.
A true RESTful API will also conform to the REST architectural constraints outlined by Fieldingโs dissertation, including: ๐๐ป
๐ธ 1. REST API: Client-Server Architecture
- The client and server are decoupled to improve scalability and allow the components to evolve independently.

๐ธ 2. REST API: Statelessness
- Statelessness means that every HTTP request happens in complete isolation. Each request contains the information necessary to service the request. The server never relies on information from previous requests. Thereโs no state.

๐ธ 3. REST API: Cacheability
- Responses can be explicitly or implicitly defined as cacheable or non-cacheable to improve scalability and performance. For example, enabling the cache of GET requests can improve the response times of requests for resource data.

๐ธ 4. REST API: Layering
- Different layers of the API architecture should work together, creating a scalable system that is easy to update or adjust.

๐ธ 5. REST API: Uniform Interface
Communication between the client and the server must be done in a standardized language that is independent of both. This improves scalability and flexibility.

REST APIs are particularly well-suited for web applications. In addition, if you are looking for the following characteristics, REST is a strong option:
- Familiarity
- Interoperability
- Development efficiency

๐น REST API: Familiarity
- Most people in your engineering team have already used โ or at least have seen โ a REST API. This type of API, being the most common, will have the shortest learning curve.

๐น REST API: Interoperability
- Due to the popularity of REST, nearly every platform and framework has a built-in library capable of interfacing with a REST API that has wide support.

๐น REST API: Development efficiency
- REST APIs are reusable, enabling developers to easily create independent microservices that work independently of one another as they are decoupled from clients and accessible by multiple applications.

REST APIs have become the most popular type of API due to their flexible and fast performance. We anticipate REST APIs will continue to be a popular choice for years to come.
With that being said, this is the end of this thread.
