Build Zoom Contact Center App

# /build-zoom-contact-center-app

Background reference for Zoom Contact Center integrations across app, web, and native mobile surfaces.

Implementation guidance for Zoom Contact Center across: - Contact Center apps in the Zoom client (Zoom Apps SDK path) - Web channel embeds (chat/video/campaign) - Native mobile SDKs (Android/iOS)

Official docs: - https://developers.zoom.us/docs/contact-center/ - https://developers.zoom.us/docs/contact-center/web/sdk-reference/ - https://marketplacefront.zoom.us/sdk/contact/android/index.html - https://marketplacefront.zoom.us/sdk/contact/ios/index.html

## 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](web/SKILL.md). - If the user is integrating native Android or iOS SDK binaries, route to [android/SKILL.md](android/SKILL.md) or [ios/SKILL.md](ios/SKILL.md). - If the user needs Contact Center call-control or queue APIs, chain with [../rest-api/SKILL.md](../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.

See [scenarios/high-level-scenarios.md](scenarios/high-level-scenarios.md) for details.

## Chaining

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

## Environment Variables

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