What are Communication APIs?

A communication API is a set of protocols or instructions that allow developers to easily implement video, voice, and messaging capabilities into any software application or web. 

Whereas, an API is just an interface allowing two software applications to communicate with one another.

How Do Communication APIs Work?

APIs generally have their own set of working protocols with each differing from the other. There are different types of APIs like REST API, WebSocket APIs, SOAP, and more. And each API has its working mechanism. Usually, communication APIs establish a framework between a business’s platform with other apps.

Businesses can easily integrate communication APIs into their existing apps. And not hire developers with proficiency and core knowledge for building chat apps. By doing so, they can streamline their workflow. Further, solving queries and enabling a better work environment.

Types of Communication APIs

We know that with a communication API, web and mobile app developers can quickly integrate pre-built communication features like messaging, voice calling, and video calling into any software app.

But, is it possible to add only video, voice, and chat capabilities? Well no, even SMS and email features can be implemented using a communication API provider.

However, below we will see the top three types of communication APIs:

  1. Video API
  2. Voice API
  3. In-app Messaging API/Chat API

1. Video API

Whether you need to build a customizable video chat solution or need to add a specific video calling feature, video APIs come in demand. 

Because they give you the flexibility to easily create richer engaging experiences in your chat apps. Want to see how easily you can build a video chat app using MirrorFly video SDK? Talk to us.

2. Voice API

Like the previous type, voice API is used to embed audio calling capability into chat apps. This type of communication API is slowly earning its pace because of exquisite speech-enabled features like group audio calling, voice-to-text translation, one-to-one audio calling, push notifications, and more. 

In addition to all the above said, some of the communication API providers like MirrorFly offer complete customizations on voice calling features, and migration with zero downtime. Learn here why you should migrate to MirrorFly from your existing API provider.

Need to add voice IVR to your chat apps? You can simply use a programmable communication API in this case. 

3. In-app Messaging API/Chat API

Messaging APIs best called MirrorFly’s in-app communication API make it possible to seamlessly add interaction capabilities like one-to-one chat, group chats, push notifications, and presence indicators into any instant messaging app in a breeze. 

Did you know that a rest-based communication API can work collectively with a video API to implement communication between apps?

What are the Benefits of Using a Communication API?

Here are some of the benefits of using a communication API:

  • Enhanced levels of security: When it comes to security and data privacy, communication APIs are built with robust encryption protocols to handle any type of intrusion and data theft. 
  • Boosts user interactions: The different types of APIs offer a frictionless medium for communication thereby enhancing user interaction within the app.
  • Quick integration: Nowadays, in-app messaging API providers like MirrorFly ensure the implementation of call and chat features into any software app within 10 minutes. Such fast API integration has become.

  • Complete scalability: It has become an evident attribute of certain providers to make their APIs scalable so that they can easily accommodate a growing user base.

To conclude, communication APIs are pillars of strong in-app interactions and retention. As a result, some businesses these days mandate the implementation of messaging features into Android, iOS, and web apps to draw users’ attention.
