/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

• Initialize platform context early.
• Build a channel item (entryId for chat/video/ZVA, apiKey for scheduled callback and campaign flows).
• Get service/client instance.
• Register listeners/delegates before user interaction.
• Start flow (fetchUI, startVideo, or web SDK open/show path).
• Handle engagement state changes (start, hold, resume, end) and context switching.
• 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.
