Importance of API and How Does it fit into Your Business Strategy

Exploration is the engine that drives innovation. Innovation drives economic growth.

Edith Widder

In this era of digitization, it is essential for businesses to get with the times to increase their revenue margins and amplify operations. Integrating technology into businesses has become necessary for survival and sustenance. One such imperative aspect businesses cannot overlook is API, an Application program interface. APIs act like a bridge, connecting one program with another allowing an exchange of information between programs. But how can these APIs benefit a business?

Here is an overview of APIs and why they are a must-have for a business.

API in Business: Engines Under the Hood!

Application programming interfaces (APIs) are engines under the hood that run the show for businesses. Let us consider this instance: when we visit a restaurant, we place our order to the waiter. The waiter conveys the food we want to relish to the chef in the restaurant’s kitchen. After the food is prepared, the waiter serves the same to us.

Here, the waiter is the critical link between the restaurant’s kitchen and the guests. Similarly, APIs are like messengers, taking requests from users and conveying the requirement to the system or programs, telling them what needs to be done, and returning the response or output to the end user.

APIs are the right resource to fuel innovation in the world of business. With APIs, businesses can avoid spending unnecessary time and effort reinventing the wheel and instead use readymade solutions to develop products. Some high-end technologies, like machine learning algorithms, and image recognition software are extremely resource-intensive to create. However, APIs allow even small applications to access these technologies and pave the way for innovation.

As an IT solution, API enables independent software to communicate or exchange data or services and connect several applications together.

The API Value Chain

Different Types of API

APIs are used immensely in web services. Some of the common types of API include:

  • Partner APIs facilitate business-to-business activities. They can be used by businesses to selectively share their data with outside firms by connecting internal systems with external parties.
  • Internal APIs are used within an enterprise or B2B firm to connect systems and data within the business, like the use of an API to connect a company’s payroll and HR systems.
  • Composite APIs combine two or more APIs to create interdependent operations. They are usually used to improve the performance and speed of individual APIs.

API Protocols and Architectures

API requires rules and structures to govern its operation. There are three popular formats or architectures with unique features that are employed to create APIs:

  • Representational State TransferREST architecture separates the front and back ends of the API, facilitating the exchange of information; it provides flexibility in development and implementation. As it stores no data between requests, REST supports caching and can also operate through API gateways and load balancers.
  • Remote Procedural CallRPC architecture creates simple means to send multiple parameters and receive results. RPC invokes executable actions or processes by employing two different languages, JSON and XML, for coding.
  • Simple Object access Protocol – SOAP architecture creates web APIs, usually with XML. As it supports a wide range of internet communication protocols found across the internet, such as HTTP, SMTP, and TCP/IP, it allows developers to create APIs in varied ways and add to features and functionality.

API in Businesses Are the Root of Everything Good
