Top 10 Video Calling & Conferencing APIs & SDKs

In today’s business world, video conferencing is essential for staying connected with clients, customers, and colleagues. Whether conducting a sales presentation or participating in a team meeting, video conferencing allows you to collaborate with others in real-time.

However, for video conferencing to be successful, you need the right tools. This blog post will look at the top 10 video calling and conferencing APIs and SDKs. We’ll also provide an overview of what each tool offers and how it can benefit developers.

So whether you’re looking to build a video call app or add video conferencing capabilities to your existing app, this blog post will help you find the right tools for the job.

Get Connected With the Right Video Conferencing Tools 

A software development kit (SDK) is a collection of software development tools in one installable package. SDKs are designed to provide a developer with the essential tools to build a particular application or component.

For example, the Android SDK provides the basic tools needed to develop Android applications, while the Windows SDK provides the tools needed to develop applications for the Windows operating system.

 In most cases, an SDK will include a compiler, debugger, and other utilities. Some SDKs also have runtimes, libraries, and sample code. In the case of video calling and conferencing, an SDK provides the code and libraries necessary to build apps that can make calls and hold meetings using a particular service. 

SDKs usually include an API (application programming interface) that defines how the various components of the system interact. For video calling and conferencing, the SDK will typically include audio and video stream libraries and code for managing user authentication and setting up calls. 

In addition, SDK may provide tools for testing and debugging applications and documentation to help developers get started. Using SDK allows developers to save time and effort when creating video calling and conferencing applications.

Benefits of Video Calling & Conferencing APIs & SDKs

There are many benefits to using video calling and conferencing APIs and SDKs, here are six benefits of using these tools for your business: 

Ease of Integration

Most video conferencing providers offer libraries and tools that can be quickly integrated into your application. This reduces development time and ensures a smooth user experience.

Robust Features

Many SDKs and APIs have advanced functionality, such as screen sharing and file transfer. This allows you to build more powerful and flexible applications that meet your users’ needs.


Video conferencing tools are designed to handle high traffic volumes, making it easy to scale your application as your user base grows.


Many video conferencing solutions offer built-in security features, such as end-to-end encryption and two-factor authentication. This helps protect your users’ data while ensuring the integrity of your application.

Global Reach

With video conferencing, you can connect with anyone, anywhere in the world. This is a valuable tool for businesses with international clients or employees. 

Increased Productivity

Video conferencing can save time by eliminating the need for travel. It can also help reduce costs associated with travel, such as lodging and airfare. For example, if you’re working on a project with someone else, you can use video conferencing to share files and brainstorm ideas.
