API Development & Integration – A guide to What is an API, Its Aspects, Working & Dominance

April 25, 2022

What is an API?

API Development and Integration are at the forefront of the digital landscape, revolutionizing how software applications interact. An API, which stands for Application Programming Interface, is a crucial bridge, enabling seamless communication and efficient data exchange between diverse systems.

With APIs driving a thriving economy, companies recognize their significance and leverage API Development and Integration company to offer developers specialized functionalities and services. This widespread adoption underscores the importance and value of APIs, as they empower businesses to achieve efficient integration and fuel innovation across various industries.

How does API work?

Imagine yourself sitting in a restaurant, holding a menu in your hands. In this scenario, the restaurant’s kitchen represents a system responsible for preparing your food. To establish a seamless communication link between the kitchen and your table, we need a mediator, much like a waiter in a restaurant or an API in programming.

In this analogy, the waiter acts as a messenger or an API, taking your order and conveying it to the kitchen. The waiter then delivers the prepared food back to your table.

To grasp this concept better, let’s consider a real-life example. When you book a train ticket online, you encounter various options such as selecting the destination city, journey dates, boarding station, seat class, and more.

To successfully book a seat, all these options, along with other necessary details, need to be set. However, what if you’re not directly using the website of the railway service provider (e.g., Indian Railways)? Instead, you opt for an aggregator website like yatra.com or makemytrip.com. In this case, the ticket booking service interacts with the Indian Railways’ website through API Development and Integration. The API acts as a liaison, requesting the necessary information from the Indian Railways’ server and providing a response to the user.

API Development and Integration facilitate seamless communication and data exchange between different systems or platforms, enabling efficient interactions and enhancing the overall user experience.

Aspects of modern API

  1. Modification timestamp/Search by criteria.
    All modern-day APIs provide search functionality to search datasets by their date.

  2. Paging
    A standard API will put restrictions on the amount of data requested in one attempt and the frequency of data requests. In addition, it should notify how many pages are left to be retrieved.

  3. Sorting
    An API should allow for sorting data according to the time of modification at least.

  4. JSON support / REST:
    Although an API doesn’t have to be RESTful to be considered good, most of the new APIs are REST APIs that support JSON and other formats like TXT, CSV, and XML.

  5. Authorization via OAuth:
    A good API must offer authorization via OAuth. OAuth means that if a user wants to connect an application with another application via some services, they can self-authorize by granting service access to the application.

  6. Documentation support:
    Last but not least, an API must have good documentation for the developers. MailChimp or Twilio are good at this.

Advantages of using APIs for developers:

  1. Automation
  2. Availability of new data
  3. Integration becomes
  4. smooth
  5. Personalization

Advantages of using APIs for business:

  1. Increases productivity
  2. Saves Cost
  3. Encourages innovation
  4. Collects data for
  5. Intelligence analytics
  6. Creates new revenue
  7. Opportunities


APIs are incredibly diverse, coming in various shapes and sizes. In today’s world, APIs are treated as valuable business products rather than mere lines of code. Developers now adopt a standardized approach to creating APIs, leading to enhanced focus on security and governance.

This shift in mindset reflects the recognition that APIs play a critical role in driving business growth and innovation. As a result, developers exhibit a strong commitment to ensuring the reliability, scalability, and security of APIs. They adhere to robust security practices and implement effective governance strategies throughout the API development process.
