API integration

KATASIS has an outstanding experience in API creation and Integrations, we can provide both  simple and complex, standardized or custom solutions for your queries. Our team will be glad to provide free consultation and perform the development for you. Contact our representative right now! Alternatively you can learn some more information about API, by reading the information below.

Let's start with the basics: what is an API? The abbreviation stands for Application Programming Interface, or an interface for programming applications. The name, like, speaks for itself, but it is better to consider a more detailed explanation.

As already mentioned




, the API is, first of all, the interface. An interface that allows developers to use ready-made blocks for building an application. In the case of the development of mobile applications, the library can be used as an API for working with the "smart house" - all the nuances are implemented in the library, and you just refer to this API in your code.

In the case of web applications, the API can give data in a different format from the standard HTML, which makes it convenient for them to write their own applications. Third-party public APIs most often give out data in one of two formats: XML or JSON. In case you decide to make an API for your application, remember that JSON is much more concise and easier to read than XML, and services that provide access to data in XML format gradually abandon the latter.

Examples of API in web applications

Some application - for example, Github - has its own API, which other developers can use. The way they will use it depends on the capabilities that the API provides and on how well the developers' fantasy works. API Githhaba allows, for example, to receive information about the user, his avatar, readers, repositories and many other useful and interesting information.

If you take, for example, the Twitter API, then the interface of this service can give you information about the user's tweets, its readers and those who read it, and so on. This is only a small part of the opportunities that anyone can implement, using the API of a third-party service or creating their own.

Based on the API, such things as 2GIS cards, all kinds of mobile and desktop clients for Twitter and Vkontakte are built. All their functions became possible precisely because the corresponding services have high-quality and detailed documented APIs.

In case someone else does not know, it's worth noting that curl has nothing to do with the API and is used in operating systems to send and receive data through the terminal.

Why is the API needed for your application?

There are several situations in which you might want to create an API for your own lovingly written and refactored application.

Mobile app! Yes, a lot of mobile applications for various services work with the API of these services. You described the API, made a simple mobile application, and a client with a smartphone will receive information to your device through the API. It's convenient, it's reasonable, it makes sense.

Opensource. It's getting better if you use the open source :) In fact, if your application has a certain audience that uses it, why not turn it to your advantage? Well, the benefit of the audience, of course, too. Create an API with which your users can create new clients for your application, new services based on it, and, perhaps, open new faces.

Maximum separation of the frontend and the backend. For example, when using front-end frameworks.

One API is not enough

Creating a full API for your application is only half the battle. How do you expect to access the API? How will your users address it?

The first thing that comes to mind is the usual series of HTTP requests in order to obtain the necessary information, and this is the wrong answer. The most obvious way in this case is not the most convenient and simple. It is much more reasonable to create a special library for working with the interface, which will describe all the necessary ways of obtaining and sending information using API.

Once again we will use Github to give an example: to work with the IPA of this excellent service (and the interface it provides the most extensive opportunities), several libraries have been created in different languages, for example, the Octokit gem. In the documentation for such libraries (and an exemplary gem), any interested developer will be able to find all the necessary ways of obtaining information from the Gitkhab and sending it back through the service API.

So, if you are creating your own API, think about it, maybe you should also consider creating libraries to work with it in the most common languages. And be prepared that at a certain level of demand for your application, someone else can create their own library to work with your API. This is normal.
