# /build-zoom-virtual-agent

Background reference for Zoom Virtual Agent across:
- Web campaign/chat embeds.
- Android WebView wrappers.
- iOS WKWebView wrappers.
- Knowledge-base sync and custom API ingestion.

Official docs:
- https://developers.zoom.us/docs/virtual-agent/

## Routing Guardrail

- If the user is implementing Contact Center app surfaces inside Zoom client, chain with [../contact-center/SKILL.md](../contact-center/SKILL.md).
- If the user needs backend knowledge-base CRUD or automation scripts, chain with [../rest-api/SKILL.md](../rest-api/SKILL.md) and [../oauth/SKILL.md](../oauth/SKILL.md).
- If the user asks only for website bot embed and campaign controls, stay on [web/SKILL.md](web/SKILL.md).
- If the user asks for mobile native wrappers around web chat, route to [android/SKILL.md](android/SKILL.md) or [ios/SKILL.md](ios/SKILL.md).

## Common Lifecycle Pattern

1. Configure campaign or entry ID in Virtual Agent admin.
2. Initialize SDK in web or WebView container.
3. Wait for readiness (`zoomCampaignSdk:ready` or `waitForReady()`) before calling APIs.
4. Register bridge handlers (`exitHandler`, `commonHandler`, `support_handoff`) when native orchestration is needed.
5. Handle conversation lifecycle (`engagement_started`, `engagement_ended`) and UI state.
6. End chat (`endChat`) and clean up listeners.

## High-Level Scenarios

- Website campaign launcher with contextual customer attributes.
- Mobile app WebView chat with native close/handoff bridge.
- External URL handling via system browser vs in-app browser policy.
- Knowledge-base sync from external systems using custom API connector.
- Cross-team support flow that escalates from bot to live support with handoff payload.
