build-zoom-team-chat-app

A reference skill for building Zoom Team Chat integrations, including messaging, chatbots, cards, buttons, slash commands, and webhooks. Zoom Team Chat is Zoom's messaging service.

In plain words
What is it for?
Use it when implementing deterministic REST integrations, chatbot apps, webhooks, retries, or user-scoped Team Chat features.
Why use it?
It helps choose the correct Zoom interface and authentication method, since sending messages as a user and sending them as a bot use different APIs.

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 B, and why

build-zoom-team-chat-app scanned grade B with 1 finding 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 3d 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.

Sends data to an external URLmediumData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

const response = await fetch('https://api.zoom.us/v2/chat/users/me/messages', { method: 'POST',

How it starts

The opening of the file, as written. The whole thing — 727 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/build-zoom-team-chat-app

Background reference for Zoom Team Chat integrations. Use this after the workflow is clear, especially when the Team Chat API versus Chatbot API distinction matters.

For agent-driven MCP tooling that sends or edits messages, manages Team Chat channels, or adds channel members through Zoom's hosted MCP server, use ../zoom-mcp/team-chat/SKILL.md. Keep this skill as the default for deterministic REST API implementation, chatbot apps, webhooks, retry logic, and production backend control.

Read This First (Critical)

There are two different integration types and they are not interchangeable:

  1. Team Chat API (user type)

    • Sends messages as a real authenticated user
    • Uses User OAuth (authorization_code)
    • Endpoint family: /v2/chat/users/...
  2. Chatbot API (bot type)

    • Sends messages as your bot identity
    • Uses Client Credentials (client_credentials)
    • Endpoint family: /v2/im/chat/messages

If you choose the wrong type early, auth/scopes/endpoints all mismatch and implementation fails.

Official Documentation: https://developers.zoom.us/docs/team-chat/
Chatbot Documentation: https://developers.zoom.us/docs/team-chat/chatbot/extend/
API Reference: https://developers.zoom.us/docs/api/rest/reference/chatbot/

New to Team Chat? Follow this path:

  1. Get Started - End-to-end fast path (user type vs bot type)
  2. Choose Your API - Team Chat API vs Chatbot API
  3. Environment Setup - Credentials, scopes, app configuration
  4. OAuth Setup - Complete authentication flow
  5. Send First Message - Working code to send messages

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.
