contact-center/web

A developer guide for adding Zoom Contact Center chat, video, or campaign features to a website. It also covers events, application context, and communication between an embedded frame and its parent page.

In plain words
What is it for?
Use it to embed Contact Center features, respond to engagement events, preserve state by engagement, connect website context, and debug iframe, postMessage, content-security, and allow-list issues.
Why use it?
It helps avoid common web-integration failures, such as calling a campaign library before it is ready, losing state when conversations change, or overlooking browser security settings.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

contact-center/web scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

94% identical to contact-center/web — 6 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Zoom Contact Center SDK - Web

Official docs:

  1. concepts/lifecycle-and-events.md
  2. examples/app-context-and-state.md
  3. references/web-reference-map.md
  4. troubleshooting/common-issues.md

Integration Modes

  1. Contact Center App in Zoom client:
  • Zoom Apps SDK engagement APIs/events.
  1. External website embed:
  • Campaign SDK/web scripts (zoomCampaignSdk pattern).
  • Video client initialization pattern.
  1. 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

Operations

  • RUNBOOK.md - 5-minute preflight and debugging checklist.
Files

What ships with it

5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
