Video Chat SDK and API

We all love video. It gives us the power to make an immediate, personal connection to our family, friends, colleagues, partners and clients. 

The demand for conferencing tools has never been greater. As I’m writing this, the world is suffering from COVID 19. Remote communication is of the essence because of social distancing. But after the pandemic is gone, the trend of remote collaboration will become even stronger, as experts say.  

That’s why creating an app with the video feature seems like a promising venture. For building one, you’ll most likely need a solid video chat SDK and API (for iOS, Android or websites). But what solution to choose? 

At Riseapps, we made a little research on video call SDK and API providers and shared our experience in choosing a suitable tool. Be you a start-up owner or CTO working for a worldwide in-house center, hopefully, find some useful information here.  Let’s get started!

What are SDKs and APIs?

In case some of our readers are not tech-savvy, here’s a very short explainer. 

An SDK (software development kit) is a set of tools that makes building of the apps easier. Imagine your developers wrote their code from scratch for every app feature. It would be extremely time-consuming and tedious! This is where SDKs come in – with tools like libraries (pieces of code), visual editors (e.g. to layout graphical elements), debuggers, and… APIs.  

An API is an interface allowing different types of software to communicate with each other and exchange data. Simply put, an API provides a technical infrastructure helping different tools to work together – in our case – for building the video chat feature.

Need For Video Call API and SDK

The video communication platform as a service (PaaS) market has been constantly evolving, being reinforced with new players. And it’s exactly self-service APIs that drive this market.  

The reason video call APIs and SDKs are in high demand are twofold: 

  • Faster software delivery

The tools dramatically simplify the process of building cross-platform live chats. The robust APIs are easy and quick to implement. As a rule, using them also means you’ll have fewer bugs. 

  • Saving resources (workforce, money)

With a suitable video call API and SDK, developers can focus on building your app instead of becoming experts in creating specific chat solutions.  

Let’s say you need to add a video chat to your PHP (with mySQL) site. Some basic integration procedures might take a few hours, while building your own communication tool could require a couple of months.

Video Calling SDK and API Features

To create a rich experience for app users, video calling SDK and API providers usually pack their tools with a variety of features. We’ll list some of them here. 

  • Various conferencing formats

You can implement one-to-one, group chats or large scale broadcast sessions in your tool. 

  • Screen sharing 

When hopping on a call, users of your app will be able to present their screen, draw on it, etc. 

  • Messaging

In a video session, your app users will be able to send data and chat messages to each other.

  • Recording 

Your app can have the built-in recording function.

  • Voice feature 

Chat sessions can be video and voice, voice-only or mixed.

As we’ll see below, the functionality provided by various solutions is the first thing we might pay attention to when choosing a video SDK for Android, iOS or websites. 

How to choose the right Video Chat API (SDK) for your tool?

Developing your own tool with a video feature, you might come up with a question: how to choose the right video chat SDK/API? 

We addressed this question to Dmytro U., a senior react native developer at Riseapps. Giving the answer, he started with a short foreword that I included as well. 

Here’s what he said: 

“All SDKs use such thing as WebRTC under the hood which is basically a protocol for transmitting streaming data. Many popular products implement video calls using pure WebRTC. 

As for the video chat SDK/API market, there are dozens of solid tools like Twilio and OpenTok. I must admit most of them have very similar functionality. However,

  • the capabilities of the platform are probably the first thing to pay attention to. Does the tool support all the features you need? Check out the free trial opportunities of the platform. Video chat API and SDK providers usually give free minutes for you to do preliminary testing and validation. 
  • Price is another thing to consider, as a tool can be overpriced. 
  • Finally, the tech support of the platform matters. In case their SDK has some bugs, you’ll have to communicate to the provider, probably, more than just once.”  

Following Dmytro’s advice, let’s explore some of the video chat APIs and SDKs. 

List of Top Video Chat API and SDK


Twilio provides a video call SDK

Twilio is a San Francisco-based developer platform for communication.

  • Layout and media control
  • Co-browsing and screen sharing
  • Recordings: storing is available in the Twilio cloud 

Sidenote: Since we mentioned WebRTC once more in this article, let’s give a short explanation of it. This tool allows you to add real-time communication capabilities to your app that works on top of an open standard. The technology is available on all modern browsers as well as on native clients for all major platforms.  The WebRTC project is open-source and supported by Google, Apple, and Microsoft amongst others. 

Can I build a HIPAA compliant tool using Twilio?

As noted, you can create ‘a HIPAA-compliant workflow’ using Twilio’s offerings.  Twilio’s Programmable Video claims to be “HIPAA eligible” offering “next-generation HIPAA-compliant patient care”.

The list of HIPAA Eligible Products and Services includes “TURN Relay”, “Peer to Peer Rooms” and “Group Rooms” for implementing programmable video. 

How much does Twilio cost? 

Twilio’s ‘Programmable video’ pricing starts at $0.004/min per participant for Small Group Rooms (up to 4 participants). 

‘Peer-to-peer Room’ pricing is based on the number of minutes your participants are connected to a Room. As of March 2020, it’s $0.0015 per participant per minute. 

If you happen to wonder about the Quality-Price-Ratio of Twilio or any other tool, feel free to contact us, so we could share with you our experience and assist you with choosing the most suitable SDK and API provider.

Our experience in using Video chat API and SDK  

At Riseapps, we have considerable experience of implementing video call API and SDK for iOS, Android and websites, primarily in the healthcare industry. 

For example, not a while ago we built Kego – an online urgent care clinic where patients can see a doctor via video conference using our secure HIPPA compliant app.

We used a Programmable video SDK of one of the tools mentioned above to implement robust one-to-one calls.

Kego platform is built using a video chat sdk

Needless to say, security and compliance were the most important for us in this case. We didn’t have the requirement to implement features like screen sharing or video recording. However, it was theoretically possible within the SDK provided. 

The video feature in Kego was implemented for both – website and mobile (iOS, Android) platforms. This call functionality made all the difference for a robust and easy-to-use tool that seamlessly connects patients with their caregivers.


To wrap it up, video chat app SDK and API for iOS, Android and web are golden, as they help save time, money and workforce. Since they allow implementing video features from a third-party tool, your developers don’t have to build them from scratch. 

Basic functionality of a video chat API and SDK, price and support level are the key factors to pay attention to when choosing the appropriate solution. 

There are a lot of players on the market. In this article, we’ve listed 4 of them featured by providers like Twilio, Vonage, Agora and Vidyo. Having similar functionality, they all can be used for building a HIPAA compliant tool.
