Integration Modes
- Contact Center App in Zoom client:

- External website embed:
- Campaign SDK/web scripts (
zoomCampaignSdkpattern). - Video client initialization pattern.
- Smart Embed:
- iframe +
postMessageevent 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.
