What is a Video Chat API/SDK?

In simple terms, APIs and SDKs are interface tools that will allow you to embed a third-party video chat or live video call online service into your products, whether those are mobile applications or browser-based web applications.

What that means is that your developers don't need to build such applications from scratch, which would involve a great deal of resources - monetary, human, and technological. Instead, the SDK or API piggybacks on third-party infrastructure that's purpose-built for high performance, low latency, and an overall superior user experience.

To break this down further, an API or Application Programming Interface lets you access the server and applications at the back end and bring the front end into your own application, whereas an SDK is more elaborate, allowing you to build extra capabilities into your own existing web and mobile apps.

In this case, the extra capability is a live video call or video chat service that's seamlessly integrated in a way that allows you to leverage the capabilities of the service provider platform that you're using.

So, what are the essentials of such a platform and its API/SDK offerings that you need to look for when reviewing possible service providers? In the next section, we'll discuss the must-haves of video API and SDK offerings.

6 Must-have Voice/Video Calling Features for Businesses

1. Video Conference and Recording

Businesses that use API/SDK platforms for live video call and chat will obviously need the ability to conference a large number of people from different locations using different modes and devices - iOS, Android, and Web. The video should be of HD quality and should accommodate hundreds of simultaneous users. In addition, the platform must give you the ability to record these sessions for various purposes - recording the minutes of a meeting, preserving the video for training purposes, etc.

2. Low Latency

This is one of the crucial considerations is latency. The fact that not all users will have robust connectivity makes this even more important. You want all participants to have a low-latency experience so conversations are seamless and uninterrupted because of poor Internet connections or resource-intensive activity. Remember that you're building this for the web as well as mobile, so this is definitely a key factor to take into consideration when building a video interface.

3. Live Broadcasting

When organizing webinars and such events for a large number of participants, the ability to live-stream your video broadcast to a vast network of users is vital. The platform that you choose for your live video chat application should, therefore, provide you with this key feature. Of course, it goes without saying that you should be able to stream in HD and without any latency worries that are typical of video live streams.

4. Screen Sharing

In any presentation or webinar scenario, the presenter or host should have the ability to share their screen with others in order to use their visual material as a complement to the presentation. You're probably familiar with screen sharing on platforms such as Zoom and Google Meet, so why not build this feature into your own mobile app or website?

5. Cross-device Support

Since video chats are remote by definition, it stands to reason that participants will be using a variety of different devices running on different platforms or operating systems. For instance, iPhones running iOS, Samsung Galaxy Tabs running the latest Android, or even modern browsers on Windows and Mac computers should be able to access your video API setup. Therefore, using a platform that is compatible with these different configurations is a must-have.

6. Group Video Conferencing Vs. One-to-One Video Chat

Companies that follow a remote workforce model aren't the only ones that need a robust live video call solution. What about situations where managers need to have performance review meetings with their direct reports? In such cases, it's important to have the ability to both group-conference as well as get on one-to-one video chats. In short, no matter the number of people on the call, the platform should support the requirement.

4 Reasons Why You Need ZEGOCLOUD for An Enhanced Video Call App

Put simply, ZEGOCLOUD ticks all the right boxes when it comes to quickly integrating video chat into or creating a custom video chat app within your own code. Once you've built it and it becomes a part of your mobile or web app, you retain full control over the customizations but also have the benefit of keeping all the core hardware assets off-prem. In short, you get the slick and performant front-end while the heavy lifting and hard coding work is done at the back end. Your developer will be able to implement live video chat in minutes and hours rather than in days and weeks. What's that worth to your business? And that's not all. Here are just a few of the features that users can enjoy with ZEGOCLOUD:

1. Virtually Unlimited Scalability

What would you say if you had the ability to connect 20 people from around the globe on a single video chat, but you're able to extend that to 1+ billion users? You'd say "That's amazing!", right? That's the sort of scalability offered by ZEGOCLOUD - the right size for your current business and your future business so you don't have to worry about your video chat platform growing alongside your sales and your reach.

2. Flexibility with Data Residency and Infrastructure

Where would you prefer all your customer conversations and user data to reside - on-prem, off-prem, your own cloud versus a third-party solution? ZEGOCLOUD flexibly allows you to choose where you hold your data, and you can do so in a secure manner the way large enterprise companies do. There's no need to worry about having to invest in expensive infrastructure when your video chat platform supports any on-prem or off-prem solution.

3. Easy Integration with Any Third-party Application

You can only achieve the next level when your video chat API platform can be quickly integrated into any web or mobile application no matter what platform it is built on. With support for all the most popular architectures and operating systems, ZEGOCLOUD allows you to focus your developer resources where they're needed - for your own applications. The video chat API/SDK makes it easy to be up and running within hours, and the UIKits can help you achieve the same thing literally in minutes.

4. Flexibility with Pricing

ZEGOCLOUD offers fair and transparent pricing for video calls and audio calls. The nominal charges will cost you less in the long run so your returns are earned faster than with other platforms. The best part is that you're charged separately for video and for audio. For instance, if two users have their webcams and microphones on and a third user only has audio, you won't be charged anything for video usage for the third user. Similarly, if there's a fourth user who's only using their camera with no audio, you won't be paying for audio minutes for that user. This granular billing can save you thousands of dollars a year when video and audio are decoupled.
