What is REST API? An Overview | Liquid Web

What is REST?

The REST acronym is defined as a “REpresentational State Transfer” and is designed to take advantage of existing HTTP protocols when used for Web APIs. It is very flexible in that it is not tied to resources or methods and has the ability to handle different calls and data formats. Because REST API is not constrained to an XML format like SOAP, it can return multiple other formats depending on what is needed. If a service adheres to this style, it is considered a “RESTful” application. REST allows components to access and manage functions within another application.

REST was initially defined in a dissertation by Roy Fielding’s twenty years ago. He proposed these standards as an alternative to SOAP (The Simple Object Access Protocol is a simple standard for accessing objects and exchanging structured messages within a distributed computing environment). REST (or RESTful) defines the general rules used to regulate the interactions between web apps utilizing the HTTP protocol for CRUD (create, retrieve, update, delete) operations.

What is an API?

An API (or Application Programming Interface) provides a method of interaction between two systems.

What is a RESTful API?

A RESTful API (or application program interface) uses HTTP requests to GET, PUT, POST, and DELETE data following the REST standards. This allows two pieces of software to communicate with each other. In essence, REST API is a set of remote calls using standard methods to return data in a specific format.

The systems that interact in this manner can be very different. Each app may use a unique programming language, operating system, database, etc. So, how do we create a system that can easily communicate and understand other apps?? This is where the Rest API is used as an interaction system.

When using a RESTful API, we should determine in advance what resources we want to expose to the outside world. Typically, the RESTful API service is implemented, keeping the following ideas in mind:

  • Format: There should be no restrictions on the data exchange format
  • Implementation: REST is based entirely on HTTP
  • Service Definition: Because REST is very flexible, API can be modified to ensure the application understands the request/response format.
  • The RESTful API focuses on resources and how efficiently you perform operations with it using HTTP.

The features of the REST API design style state:

  • Each entity must have a unique identifier.
  • Standard methods should be used to read and modify data.
  • It should provide support for different types of resources.
  • The interactions should be stateless.

For REST to fit this model, we must adhere to the following rules:

  • Client-Server Architecture: The interface is separate from the server-side data repository. This affords flexibility and the development of components independently of each other.
  • Detachment: The client connections are not stored on the server between requests.
  • Cacheability: It must be explicitly stated whether the client can store responses.
  • Multi-level: The API should work whether it interacts directly with a server or through an additional layer, like a load balancer.

An API-First Approach For Designing Restful APIs | Hacker Noon

I’ve been working with Restful APIs for some time now and one thing that I love to do is to talk about APIs.

So, today I will show you how to build an API using the API-First approach and Design First with OpenAPI Specification.

First thing first, if you don’t know what’s an API-First approach means, it would be nice you stop reading this and check the blog post that I wrote to the Farfetchs blog where I explain everything that you need to know to start an API using API-First.

Preparing the ground

Before you get your hands dirty, let’s prepare the ground and understand the use case that will be developed.

Tools

If you desire to reproduce the examples that will be shown here, you will need some of those items below.

  • NodeJS
  • OpenAPI Specification
  • Text Editor (I’ll use VSCode)
  • Command Line

Use Case

To keep easy to understand, let’s use the Todo List App, it is a very common concept beyond the software development community.

A Simple Guide to API Development Tools

APIs can be as simple as 1 endpoint for use by 100s of users or as complex as the AWS APIs with 1000s of endpoints and 100s of thousands of users. Building them can mean spending a couple of hours using a low-code platform or months of work using a multitude of tools. Hosting them can be as simple as using one platform that does everything we need or as complex as setting up and managing ingress control, security, caching, failover, metrics, scaling etc.

What they all have in common are three basic steps to go from nothing to a running API.

Each of these steps has its own set of tools. Here are some I’ve used and popular alternatives.

Design

REST is the most popular API interface and has the best tooling. Our design output for REST services always includes an OpenAPI specification. The specification language can be tricky to get right in JSON (how many curly brackets?) or YAML (how many spaces?) so a good editor saves a lot of time.

Four popular ones are:

I’ve only used Swagger and Postman but both Insomnia and Stoplight look interesting. All of them offer additional functionality like documentation, testing and collaboration so are much more than just specification generators.

A Simple Guide to Planning API Roadmaps

APIs - the current “big thing” - offer the opportunity for modern organizations to unlock new and lucrative business models. The article below covers some tips on how to spin the API flywheel and leverage its possibilities.

In the API economy, a successful service can gain popularity and be utilized in ways unpredicted and often inconceivable by its original owners. The very flexible nature of the technology opens many doors, including business collaborations, reuse in third-party products or even conquering hardware barriers by reaching a spectrum of devices.

What to consider

Taking the builder’s perspective

Important note: Most of the time API consumers are not the end-users but rather the app developers. Any new venture ought to be supported with excellent learning resources and descriptive documentation. These things combined will ensure a top-notch developer experience and encourage adoption of your product, increasing its visibility in the market.

More than the revenue

While in the simplest scenario, the most popular API business model is revenue via service charges, there are several other goals:

  • **Growth **- APIs are finely-grained and, usually, short-term projects that bring lots of value. Decoupling sectors of your business and encapsulating them in the form of concise, dedicated APIs enable teams to work in parallel, encouraging company growth.
  • **Reach **- By building APIs for wide use, the organization can extend its group of recipients and open new opportunities to cooperate with other players in the market and discover new collaborations.
  • **Compliance **- Products and services implemented as an API ecosystem can freely exchange data between one another, whether they are internal or external.
  • **Insight **- The rate of use of APIs will surely give an idea of what consumers value the most. Also, implementing APIs alone helps to clarify what pieces of your business are crucial. This helps to revise implementation details and encourages reflection of your current technological solutions.
