Adding video conferencing capabilities to your app or website can enhance user engagement, but building these features from scratch is hard. Before integrating them into your platform, you must solve challenges like real-time audio and video processing, security, and complex UI.
Thankfully, cutting-edge conferencing solutions have come to the rescue. These tools help developers add robust video solutions to their applications, saving valuable time and resources in the process.
This article highlights what to look for in a conferencing API or SDK, the leading providers, and their pricing plans.
What is a Video Conferencing API or SDK?
An API is a set of protocols that allow different software programs to communicate with each other.
An SDK is a collection of software tools and components. These help developers build applications with a specific framework, platform, or API. Usually, they include code libraries, documentation, and code samples or snippets.
Real-time communication services cater primarily to app developers. They can get started by obtaining API credentials, setting up a server-side web application, and developing a client-side web application.
Specific to video conferences:
- APIs let you access specific functionalities, like initiating calls and managing participants.
- SDKs provide code and documentation to make it easier to use the video API.
SDKs are invaluable tools for integrating real-time video conferencing functionality into various platforms, such as:
- Communication apps: Face-to-face interaction within messaging platforms.
- Telemedicine apps: Video chat between patients and healthcare professionals.
- Social media platforms: Video calls to connect with friends, fans, and family.
- E-learning platforms: Live lectures.
What Are the Benefits of Using an API over building Conferencing In-house?
Faster Adoption
Providers offer pre-built video conference capabilities that you can quickly integrate into your product. This accelerates time-to-market by avoiding months or years spent developing these complex features in-house. You also capitalize on rapidly evolving video tech with minimal custom coding.
Less In-House Maintenance
Third-party solutions enable you to offload ongoing maintenance, updates, and upgrades to the provider. This frees your engineers to focus on your core product experience.
Better Security
Components have built-in, enterprise-grade security measures like encryption and access permissions. Providers identify vulnerabilities that individual dev teams may miss.
More Cost-Effective
There's no need to maintain complex server architectures. So, though there can be an upfront investment, in the long run, it's cost-effective. Plus, you pay for only what you use while benefiting from economies of scale. Capital is freed for revenue-generating initiatives.
Faster Time to Market
You integrate proven, ready-to-use modules versus undertaking lengthy development cycles yourself. Businesses can then quickly launch products and services, gaining a competitive edge in the market.
Scalability
Video conferencing solutions must handle scale seamlessly, from small group calls to large broadcasts. Ready-made components leverage cloud infrastructure for elastic scaling. You gain access to virtually unlimited capacity compared to self-hosted environments that may be prone to bottlenecks.
