What is API? Why is it important in mobile app development?

With the passage of time, the process of mobile app development has transformed dramatically. New and advanced features have come to the surface in recent years. Mobile apps have become more complex in terms of functionalities and integrations. Users now demand biometric fingerprint unlock on apps, geolocation, social preferences, and more. To achieve all this flawlessly, API, or Application Programming Interface, plays a major role. If you’re planning to launch your first app, you need to outsource your app project to the best mobile app development company to help you with API integrations.

What is API?

Before we begin with why API is so paramount in app development, let us first understand what API is. API is the abbreviated form of Application Programming Interface, a software-to-software interface or intermediary that allows applications to interact with each other and exchange data. It is nothing but an API through which you access Facebook, make calls, or check weather updates.

Put simply, applications in a mobile device access and share data with one another by using APIs to ensure a smooth and user-friendly mobile experience. API is the pillar of the mobile world because it defines the way how users interact with technology.

Through a set of protocols, API allows the applications to communicate with each other without user intervention. API is associated with SDK, and both work together to make the app development process successful. SDK is the Software Development Kit comprising different development tools that aid in the design and development of apps in a specific framework and development platform.

If you go a little deep, API is that part of mobile app development used to feed information. Whereas the set of tools in SDK is used for building the app.

APIs hold great importance in B2B as they have become critical in integrating data flows between users and applications.

Saves Time – APIs save a lot of time for the developers by minimizing the need for coding in an application. Since APIs are easily available, mobile app developers can use them in their apps and streamline the process of app functions. For instance, in gaming apps, developers use Google Drive or Dropbox APIs, which enable the users to store and save their current game session in the cloud and retrieve it anytime to continue playing.

Convenient – APIs make it convenient for users to sign up on any app without creating a new user profile. For instance, social media apps Facebook, and Linkedin, allow users to open an account by using their existing google email account. Also, various on-demand apps provide options to users for creating an account by using their Facebook profile. All this has become possible because of the presence of APIs in mobile apps.

Provides new functionalities – With the help of APIs, mobile apps can offer users advanced features and functions. Particularly, they use existing API services of the web with the purpose of enriching the user experiences. One of the best examples of this point is Yelp using Google Maps API. Yelp is a popular review platform used by internet users to find the best restaurants nearby based on customer reviews and recommendations from other Yelp users. It uses Google Maps API to provide you with the exact location of the restaurants you are looking for.

Enhances flexibility – Almost every application, these days, lets the user share information from one application or social media platform to another. A video from Facebook, Instagram, etc., can be shared directly with your contacts in WhatsApp because of APIs.

Social Engagement – APIs fuel user engagement on social media platforms by connecting one platform with the other. Users can now post comments and share posts and videos without leaving the app. Connecting APIs also allows you to publish reviews on the app directly without creating a username or a user profile. In short, it promotes social engagement among mobile users.

Eases the process of App Testing – APIs are time-savers! Besides speeding up the app development process, it aids in automating the testing procedure. Test automation through API ensures the apps are bug-free and meet the client’s requirements – both quality and expectation-wise.
