Today, APIs are known as the core basis of our digital transformation that allows businesses to unlock the true power of their digital values, support collaboration, innovation and promote seamless user experience.

Today, APIs are known as the core basis of our digital transformation that allows businesses to unlock the true power of their digital values, support collaboration, innovation and promote seamless user experience.


A vast number of companies are starting to realize the benefits of reusable APIs and OAS as approaches that ensure the IT-producing is on a time and budget and the needs of the business and customers are met.


What is API?


In the simplest term, API (Application Programming Interface) is a software that acts as an intermediary allowing two applications to communicate to each other.


To put it in other words, API is a set of protocols and instructions that specify how one software can interact with another without human intervention.


For example, let's say you have an e-commerce website. It allows credit cards for buying. Your clients do not see the communication between your software and the credit card's authentication program. This is run by API.


In reality, extremely powerful APIs are reusable APIs as they allow developers to reuse the similar code in multiple ways. Thus, they significantly reduce the development costs and time to market and improve the user experience.


What are OAS and Swagger?


To build and maintain APIs, designers, developers, and testers need a common framework - API definitions and an industry standard for designing.


This is where OpenAPI Specification (OAS) comes.


OAS is set of rules and definitions (specification) for building and implementing APIs. Moreover, it is a descriptive documentation that allows you to define your entire API in a way that both people and computers can understand its capabilities.


That's why it is important API definitions to be the responsibility of all involved parties – not only producers of the API, but also its consumers.


At the end, An API is a contract that all parties, including servers and clients, need to follow.


Then, what is Swagger?


Swagger is a worldwide well-known set of tools for implementing this specification (OAS) that can help you design, create, and document APIs.


So, why do all of those terms (reusable APIs, OAS, Swagger) matter?


They help companies guarantee the basic concepts of good API – ease of use, functional completeness, and clear entity definitions.

Those concepts have a direct impact on producing a consumer-centric API that covers users' needs.


Key benefits of reusable APIs and OAS-driven approach:


  • Faster time to market - reusability and OAS allows teams to perform their tasks at a faster pace in an efficient way.


  • Better focus on the API consumer’s needs. API definitions keep stakeholders aligned on functionalities that API is supposed to have. It helps early stakeholder engagement and easier communication between them that leads to a better user experience.


  • Usability. Good usability requires clear documentation and definitions. Well documented APIs are more quickly utilized.


How can Upnetix strategy for reusable API development and OAS benefit your business?


With a professional expertise and understanding of finer details, Upnetix specialized in producing well documented, secure, and scalable APIs for the Web, mobile applications, and cloud.


Following the best API development practices, we build powerful APIs that are a solid foundation for any successful business app.


How we achieve this?


  • Increased developer productivity and lower time to market through re-use


API reusability allows us to run away from duplication of effort and lets developers build on each other’s code. Thus, time to market as well as costs are reduced.


  • Great usability


With the help of the modern API design features (e.g. style validator) in Swagger, our team is able to scale the API design process and to improve usability.


  • Consistency and efficiency through OpenAPI definitions


Clear API definitions and OAS stimulate a smooth collaboration on API development between stakeholders and all parties involved. This is extremely important when it comes to ensuring consistency and efficiency.


  • High Quality


OpenAPI definitions allow us to test every part of the system against the specification. This ensures high-quality APIs that are up to standard, reducing the risks of product fault.


We are in an unprecedented time of digital transformation. Mobile and cloud are key business drivers and the API provides an invaluable route to market.


We at Upnetix clearly know that digital transformation can only be achieved by bringing multiple technologies together. By offering the highest levels of API development services, our goal is to extend traditional technical approaches and satisfy today’s connectivity needs.
