Routing Guardrail

• If the user is building an app inside the Zoom Contact Center desktop client, stay on the Zoom Apps SDK path and use this skill plus zoom-apps-sdk.
• If the user is embedding chat/video widgets on a website, route to web/SKILL.md [blocked].
• If the user is integrating native Android or iOS SDK binaries, route to android/SKILL.md [blocked] or ios/SKILL.md [blocked].
• If the user needs Contact Center call-control or queue APIs, chain with ../rest-api/SKILL.md.

Common Lifecycle Pattern

1. Initialize platform context early.
2. Build a channel item (entryId for chat/video/ZVA, apiKey for scheduled callback and campaign flows).
3. Get service/client instance.
4. Register listeners/delegates before user interaction.
5. Start flow (fetchUI, startVideo, or web SDK open/show path).
6. Handle engagement state changes (start, hold, resume, end) and context switching.
7. End flow and release resources (endChat/endVideo, logout/logoff, uninitialize/release).

High-Level Scenarios

• Agent side-panel app that stores notes per engagementId and survives context switching.
• Browser chat/video campaigns launched from web tags.
• Native mobile customer app for chat/video/scheduled callback.
• Campaign-driven channel selection (chat, ZVA, video, scheduled callback).
• Rejoin flow for dropped video engagements on mobile.
• Smart Embed CRM softphone with postMessage event contracts.

Chaining

• Auth and in-client app identity: ../zoom-apps-sdk/SKILL.md and ../oauth/SKILL.md
• Contact Center REST workflows: ../rest-api/SKILL.md
• Cobrowse on web voice/chat channels: ../cobrowse-sdk/SKILL.md

Environment Variables

• See references/environment-variables.md [blocked] for standardized .env keys and where to find each value.
