What is a Video Calling API?

An application programming interface (API) is an intermediary that allows different software to communicate with one other and seamlessly exchange data. APIs provide out-of-the-box functionality to engineers and save them the time, money, and hassle of developing complex features like video chat in-house. A video calling API is a plug-and-play component that can be added to an existing web or mobile application to create a live audio and visual communication experience for users.

What are the Benefits of Using a Video API or SDK?

As mentioned above, APIs save app developers precious resources when building complicated features. Similar to an API, an SDK can support video chat functionality. A software development kit (SDK) is a collection of development tools in one installable package, including a compiler, debugger, and software framework. The top benefits are as follows:

  • Fast Time to Market: Ready-made video calling APIs and SDKs allow developers to stay ahead of the competition by quickly integrating functionalities that would otherwise take months to create from scratch.

  • Less Maintenance: Your video API will be the sole focus of your integration partner. Your API vendor will be dedicated to iterating and maintaining your video calling solution, allowing your development team to focus their efforts on other areas of your application.

  • More Security: Due to the sensitive nature of video and text-based chat content, video APIs are held to the highest data security standards. When you integrate them, you also integrate top-level compliance—something else your app developers won’t need to worry about.

  • Resource Conservation: Second to time, your most valuable development resource is money. Video APIs make the build vs. buy decision a cinch— while they might require a larger up-front investment, they are a more cost-effective option over time.

Must-Have Video Calling API Features

You might be overwhelmed by the number of video conferencing API options on the market. When evaluating possible solutions, check closely to make sure they at least include the following features:

  • Screen Sharing: Share content in real-time to one or more separate devices.

  • Recording: Live video recording and storage for later viewing.

  • Group Calling: Multiple participants can join a single video conference

  • Virtual Noise Cancellation: Improve the quality of your app’s video calling
