What is REST API?
A RESTful API is a software interface that permits you to GET, PUT, POST, and DELETE information via HTTP inquiries. It's based on RESTful innovation, a compositional style, and a correspondence methodology that is normal in web services development. The code that permits two programming applications to connect is known as an API for a site. REST can be considered the web's language, and it's used by browsers. For making APIs that allow clients to interface with and collaborate with cloud administrations, REST is a sensible decision. Since associating with help by means of an API is just an issue of controlling how the URL is encoded, the RESTful methodology is likewise valuable in cloud services.
When to use REST?
1. Limited bandwidth and resources
Since SOAP messages incorporate a ton of content and take up a ton of information, REST should be used when the network limit is an issue.
2. Ease of coding is a requirement
The coding and execution of a REST service are simpler than that of a SOAP service. In the event that you really want a fast web service solution, REST is the best approach.
If you require a cache and you're managing a lot of inquiries, REST is suggested. The quantity of questions made to the server rises as a result of this. The most often asked questions are kept in an interim solution after executing a cache. The first cache is checked at whatever point the client demands a resource. It won't go to the server assuming there are resources accessible. Caching could assist you with eliminating your travel time.
Top 6 Advantages of RESTful APIs
Here are a few advantages of RESTful APIs:
1. Scalable and flexible
Stateless communication and a recreated repository provide a high level of scalability and flexibility. With the REST APIs, scaling up a current site is more straightforward when it is compared with something like SOAP.
2. Easy to integrate
A decent RESTful API might be found from the very first URI. It is not necessarily the case that every application that utilizes your service will understand what to do automatically. It does, however, make things simpler for the engineer who is attempting to connect your API.
With the separation between client and server, the REST protocol makes it simple for developments across several sections of a project. Moreover, the REST API is versatile for operational syntax and platform. This allows testing in a variety of contexts throughout development.
4. Use of HTTP
The utilization of ubiquitous standards is one more characteristic of easy integration that has to do with REST over HTTP (THE most well-known implementation of REST). Discussing HTTP, the web's protocol, and outputting JSON or ATOMPub implies finding a library that can associate with you in any language and the platform is much easier.
5. Uniform Interface
While creating a REST API, engineers consent to follow similar guidelines. Therefore, the result is a consistent interface across all APIs. This interface works as an agreement between the client and the service, and it is shared by all REST APIs. How could this be valuable? At the point when developers use APIs, they require global ideas to ensure that they can communicate with each other.
6. Layered System
Each REST-enabled part has no access to components other than the one with whom it is communicating. This means, that a client who interfaces with an intermediary component doesn't be aware with whom that component will connect later. This urges developers to design separate components that are easy to upgrade.
So, we highlighted a few benefits of REST APIs, but the advantages don't stop there. REST APIs are also high-performing, consume less bandwidth, and are cost-efficient since designers can use them without third-party tools.
With the help of REST API, complications are reduced to almost zero and things get easier with low resources in context. It can manage resources effortlessly and that too with few operations. Hopefully, now you have an understanding of what REST API is and how it is better than the rest.
