build-zoom-contact-center-app

Build Zoom Contact Center App is a comprehensive reference skill for implementing Zoom Contact Center (ZCC) integrations across three surfaces: apps inside the Zoom desktop client (Zoom Apps SDK path), web channel embeds for chat/video/campaigns, and native Android and iOS SDKs. It solves the problem of navigating a broad, multi-platform SDK by routing developers to the right surface and documenting the shared engagement lifecycle, campaign handling, and version-drift troubleshooting.

Organized as a documentation tree with 27 files, it provides a routing guardrail that sends users to web, Android, or iOS sub-skills based on their integration target, plus concept, scenario, reference, and troubleshooting docs. It documents a common lifecycle pattern (initialize context, build a channel item using `entryId` or `apiKey`, get the service instance, register listeners before interaction, start the flow, handle engagement state changes like start/hold/resume/end, then release resources) and platform-specific SDK surfaces such as `ZoomCCInterface`, chat/video/ZVA/scheduled-callback services, campaign mode, and rejoin handling. Troubleshooting entries cover issues like views never appearing, sessions breaking on background/foreground, rejoin failures, stale sessions, and deprecated callback signatures.

It targets developers building agent-side apps, browser chat/video campaigns, native mobile customer apps, campaign-driven channel selection, and CRM softphone embeds. High-level scenarios and a RUNBOOK preflight checklist round out the material. This is guidance and reference documentation that points to official Zoom developer docs; it does not itself ship SDK binaries or execute privileged operations.
