An API is a means through which one can access any program functions. There are numerous ways in which this can be done and many have varying levels of simplicity and complexity as well as advantages and disadvantages. In some cases, the properties of these APIs almost overlap. This means it is typically delivered in numerous forms and REST is just one of them. A REST API enables your interaction with hosted databases. With this, you will be able to easily use the JSON API over the HTTPS. This makes it possible for you to easily create, view and even destroy databases. You will be able to trigger backups and also download them automatically.
REST stands for Representational State Transfer and refers to an approach used in web apps in order to specify the roles of the various components in the app. REST is a conventions-based approach and applies constraints on the requests placed. It adds certain functionalities to various HTTPS verbs such as overloaded, POST, DELETE, PUT and GET. It will translate the standard databases to these HTTP verbs. By following its conventions, it is possible to translate certain business logic into HTTP.
REST API, therefore, refers to the URL routes which are used to perform certain actions on some system entities. It makes use of these conventions along with data transfer mechanisms such as XML and JSON in order to execute these functions. It may also do with some authentication mechanism that you can use in building sets of APIs for creating, reading, updating and deleting records in a given system via HTTP calls. This is done statelessly.
REST API is generally used in describing HTTP based services along with data access. REST API is used when an application is able to use an HTTP client in order to send out requests and also carry out processing of responses. Several kinds of applications could make use of the RESTful APIs. For example, a desktop application or server using a third party application through its HTTP API could process responses using a RESTFul API.
There are many benefits that can be derived from the use of the RESTful services. The most important is the consistency. It means all services will be making use of same status codes in order to mean something similar. For example, a “401” typically means “unauthorized” while a “200” implies “success”. You have same requests that carry the same meaning. For example, to fetch data, it uses “GET” and to send data, it uses “POST” and so on.
It is Stateless
Another advantage of the RESTful services is the standardization and documentation of common issues such as the definition of content formats and caching amongst others. RESTful API is also stateless as specified above. What this means is every request which has been sent from a client will contain all the information that is needed in order to service that request. There is no context that is stored on some server between the requests. The session state of the request is in the client and is transferable by the server to other services in order to allow the request to hold its state for a duration before it is authenticated.
It is Cacheable
REST architecture is also cacheable. Caching can be done by both clients as well as intermediaries and prevents the reusing of data that is obsolete or inappropriate. If caching is well executed in an API, it will eliminate some client-server transactions and improve the performance as well as scalability of system.
The Simplicity of REST: It is Light
One of the reasons that the REST API is much preferred by many developers is its simplicity. Other APIs like SOPA or WS APIs have to follow so many rules and conventions and this makes them both easily discoverable as well as automatically executable. They have lots of security options too. Those other APIs seemingly have lots of formality but this can get in the way of what you wish to do and will also cost a lot more in order to maintain and also implement. With REST, you do not have to grapple with too much formality and conventions.
