Integration Modes

1. Contact Center App in Zoom client:

• Zoom Apps SDK engagement APIs/events.

2. External website embed:

• Campaign SDK/web scripts (`zoomCampaignSdk` pattern).
• Video client initialization pattern.

3. Smart Embed:

• iframe + `postMessage` event contract.

Hard Guardrails

• For campaign SDK, gate calls behind `zoomCampaignSdk:ready`.
• Persist state by `engagementId`.
• Expect context switching and background app behavior.
• Validate CSP and allow-list settings before debugging logic.

Chaining

• For in-client app APIs and auth flows: [../../zoom-apps-sdk/SKILL.md](../../zoom-apps-sdk/SKILL.md)
• For identity and OAuth: [../../oauth/SKILL.md](../../oauth/SKILL.md)
• For cobrowse workflow: [../../cobrowse-sdk/SKILL.md](../../cobrowse-sdk/SKILL.md)

Operations

• [RUNBOOK.md](RUNBOOK.md) - 5-minute preflight and debugging checklist.
