Webex Web Calling SDK: Building a Feature Showcase App

Integrating reliable voice and video calling directly into web applications can be complex, but the Webex Web Calling SDK simplifies the process. This text-only course guides you through building a comprehensive showcase application that demonstrates the full capabilities of the SDK. You will progress from understanding foundational Webex calling concepts to implementing advanced features like call controls, media handling, and session management. By reading through detailed explanations and studying practical code snippets, you will gain the confidence to implement real-time communication features in any modern web project. What you'll learn: - Understand the core architecture and authentication flows of the Webex Web Calling SDK; - Configure a local development environment and initialize the calling client; - Implement outgoing and incoming voice and video calls with robust session handling; - Build essential call controls including mute, hold, transfer, and multi-party calling; - Manage media devices, toggle camera/microphone inputs, and handle stream events; - Apply modern JavaScript patterns and error-handling best practices for real-time media. The course begins with essential terminology, SDK architecture, and authentication setups before moving step-by-step through call lifecycle management and user interface integration. You will explore structured modules that demonstrate how to assemble these features into a single, cohesive showcase application. This course is designed for web developers who are new to Webex APIs and SDKs. A basic familiarity with JavaScript and web development concepts is recommended, but no prior experience with real-time communication protocols is required.
