Zoom Web SDK

The Web SDK enables the development of video applications powered by Zoom’s core framework inside an HTML5 web client through a highly optimized WebAssembly module.

As an extension of the Zoom browser client, this SDK is intended for implementations where the end user has a low-bandwidth environment, is behind a network firewall, or has restrictions on their machine which would prevent them from installing the Zoom Desktop or Mobile Clients.

Prerequisites

To start using the Web SDK, head to the Marketplace and setup a Developer Account. Create a JWT App to get your API Key and Secret.

Install Options

To get started, either import the Web SDK through npm to an existing Node.js project or clone the sample web app (locally, or through CDN).

For direct guides on these options, reference the Integrate SDK guide.

Performance Limits

Currently, the Zoom Web SDK encodes at a maximum resolution of 360p. If a user is in a meeting with both native and browser clients, the browser client video displayed within the native client will be of lower quality due to encoding limitations.

Browser Support

The browser support of the Web SDK directly reflects that of the Zoom Web Client.

For a full guide to Zoom Web Client browser support, reference the Zoom Web Client Support page.
