This is the reference you'll need when building web apps that run inside Zoom's embedded browser, whether that's meeting sidebars, the main client home tab, or immersive video experiences with the Layers API. The skill covers the JavaScript SDK setup, in-client OAuth flows with PKCE, running contexts (inMeeting vs. inMainClient), and critical gotchas like domain allowlisting and the CDN global variable conflict that breaks apps silently. It's thorough on practical issues like blank panels and scope requirements. Use this after you've already decided to build a Zoom App rather than using Meeting SDK or webhooks. The quick start examples are Node/Express focused but the SDK patterns apply to any frontend framework.
