Advantages and Disadvantages of RESTful APIs

June 28, 2021by admin

A RESTful API is a software interface that allows you to GET, PUT, POST, and DELETE data via HTTP queries. It’s built on RESTful technology, an architectural style, and a communication strategy that’s common in web services development. The code that allows two software applications to connect with each other is known as an API for a website. REST can be thought of as the internet’s language, and it’s utilized by browsers. For creating APIs that allow users to connect to and interact with cloud services, REST is a reasonable choice. Because connecting to a service via an API is only a question of manipulating how the URL is encoded, the RESTful approach is also useful in cloud services.

When to use REST?

1. Limited bandwidth and resources

Because SOAP messages include a lot of content and take up a lot of data, REST should be utilized when network capacity is a problem.

2. Ease of coding is a requirement

The coding and implementation of a REST service are easier than that of a SOAP service. If you need a quick web service solution, REST is the way to go.

3. Cache

If you require a cache and you’re dealing with a lot of queries, REST is recommended. The number of queries made to the server rises as a result of this. The most frequently asked queries are kept in an interim solution after implementing a cache. The first cache is checked whenever the client requests a resource. It will not go to the server if there are resources available. Caching might help you cut down on your travel time.

Advantages:

1. Easy to integrate

A decent RESTful API may be found from the very first URI. This isn’t to say that each application that uses your service will know what to do automatically. It does, however, make things easier for the developer who is attempting to connect your API.

2. Use of HTTP

The usage of ubiquitous standards is another characteristic for ease of integration that has to do with REST over HTTP (THE most popular implementation of REST). Speaking of HTTP, the web’s protocol, and outputting JSON or ATOMPub means finding a library that can connect to you in any language and the platform is much easier.

3. Scalability

Stateless communication and a replicated repository provide a high level of scalability. With the REST APIs, scaling up an existing website is easier when it is compared with something like SOAP.

Disadvantages:

1. Hard to handle REST APIs

Because programming languages are not resource-oriented, the code that maps URIs to them tends to become jumbled. In fact, Microsoft did an excellent job of adopting Joe Gregorio’s URI mapping concept, which helps to ease the process a bit. On the other hand, making the REST API hypertext-driven is difficult.

2. Lack of security

Unlike SOAP, REST does not require security. REST is suitable for public URLs, but not for the transmission of private data between client and server.

3. Lack of state

Stateful methods are required by the majority of online applications. Let’s say you buy a website that has a shopping cart feature. Before making a purchase, it is necessary to know how many products are in the shopping basket. The client bears the task of maintaining the state, making the client application heavy and difficult to maintain.

Final Note:

API complexities are reduced to zero with the aid of REST, and things are easier with fewer resources in context. It can easily manage resources and perform a limited number of activities.
