Excellent API Coders, Engineers for Hire in Ukraine

API stands for Application Programming Interface, and it is a set of routines, protocols, and tools for creating software applications. An API defines the interaction of software components. In addition, they are used when programming GUI components. In other words, it is a library of functions and procedures, whose interfaces are available so that the external programs can use them. Popular APIs today are exposed using technologies such as REST or SOAP, which allow the third party programs compatible with such technology to call the functions or procedures in the library. It defines functionalities that are independent of their respective implementations, which allows definitions and implementations to vary without compromising each other. Most operating environments provide APIs, allowing programmers to write applications that are compatible with the operating environment. There are many types of APIs for operating systems, applications and websites such as web services APIs (REST, SOAP, XML-RPC), source-code APIs (J2EE, .NET.), legacy APIs (CORBA), library-based APIs (JavaScript) and others.

Questions and Answers related to API Development

What is an API (application programming interface), and how do I create one?

“An application-programming interface (API) is a set of programming instructions and standards for accessing a Web-based software application or Web tool. A software company releases its API to the public so that other software developers can design products that are powered by its service…”

What would you pickup as your official toolkit to develop back-ends or APIs, Java or Nodejs?

“If your application is IO intensive, nodejs might be a faster server side solution. If your application is computationally intensive (for example, runtime pdf generation, server side data crunching etc.) go for a Java based framework. If time to market is a concern, I would suggest sticking with the technologies that you are most comfortable with…”

What are the advantages and disadvantages of API?

“The main advantage of providing an API is that it allows your users to do more with your product or service (i.e. it increases the value of your product). This typically takes one of two forms – an integration or new functionality. An example of an integration is to push notifications from your product (such as CRM, Helpdesk) to a messaging tool such as Slack. In this way, if your customer uses Slack they can receive notifications without having to login directly to your system or check emails…”

What is the best framework to use for API development in PhP?

“I have not yet encountered a Framework that is widely used that also simplifies the more nuanced/in-depth aspects of API development (versus web app dev), which typically are: access control via JSON tokens or similar Rate limiting/tracking Versioning. These are items that most web apps just don’t deal with and are particular to APIs. There are some libraries that help with these items and plugins and micro frameworks that integrate with larger frameworks though…”

Consider asking some of these questions during a job interview to assess candidate’s skills.
