A robust video chat API and an SDK are required for integrating video chat in mobile applications. The blog gives you a peek into the top video chat APIs to guide you in picking the ideal tool for your upcoming app development project.

So let’s get started. But before we sail further, let’s take a quick look at some of the major aspects concerning video chat APIs!

What is a video chat API and SDK?

A video chat API (Application Programming Interface) refers to the tool that integrates audio and video, for enabling a device or an app to employ real-time video chat functionality. The technical infrastructure is provided by the API for setting up video communication. In other words, API is an interface that makes way for communication and data exchange between various kinds of software. A video chat API is used for directing video/audio calls and sharing files and thus ensuring a smooth communication process.

An SDK (Software Development Kit) refers to a host of tools that ease out the Mobile Application Development process. These tools include visual editors, libraries, APIs, debuggers, etc.

The key features of APIs/SDKs are:

  • Various kinds of conferencing formats
  • Messaging and voice functionalities
  • Screen sharing and recording

Reasons why You should Leverage Video call API and SDK in Your Mobile Apps

  • Both these tools enable businesses to create cross-platform live video conferencing platforms easily and quickly. Besides, robust APIs can be speedily implemented and their use can result in lesser bugs.
  • Their use saves the time and efforts of mobile app developers and they can focus on building the app instead.

How the Video Chats Function?

Video communication takes place between two clients using the VOIP i.e. Voice over Internet Protocol. Check out the steps.

  • The video chat service connected to the internet sends a request to the receiving device of the other person.
  • After receiving the call, the video and audio sent to the device get encoded and then are sent back to the other device.
  • A continual repetition of this process allows the chatting activity to go on for a prolonged period.
