Zoom Team Chat Development

Build powerful messaging integrations and interactive chatbots for Zoom Team Chat. This skill covers two distinct APIs - make sure to choose the right one for your use case.

For agent-driven MCP tooling that sends/edits messages or manages Team Chat channels 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.

API Reference: https://developers.zoom.us/docs/api/rest/reference/chat/methods/#overview Chatbot API Reference: https://developers.zoom.us/docs/api/rest/reference/chatbot/methods/#overview

The current Team Chat API Hub inventory contains 109 operations (verified 2026-07-10), including channel-owner reassignment and channel-tab migration. Use the generated Team Chat API reference for exact current paths. For the separate 20-tool hosted MCP surface, use Zoom Team Chat MCP.

• Webhook not receiving events → Webhook Setup Guide
• Messages not sending → Common Issues
• Start with quick checks → 5-Minute Runbook

OAuth endpoint sanity check:

• Authorize URL: https://zoom.us/oauth/authorize
• Token URL: https://zoom.us/oauth/token
• If /oauth/token returns 404/HTML, use https://zoom.us/oauth/token.

Building Interactive Bots?

• Button Actions - Handle button clicks
• Form Submissions - Process form data
• Slash Commands - Create custom commands

Quick Decision: Which API?

Use Case	API to Use
Send notifications from scripts/CI/CD	Team Chat API
Automate messages as a user	Team Chat API
Build an interactive chatbot	Chatbot API
Respond to slash commands	Chatbot API
Create messages with buttons/forms	Chatbot API
Handle user interactions	Chatbot API

Team Chat API (User-Level)

• Messages appear as sent by authenticated user
• Requires User OAuth (authorization_code flow)
• Endpoint: POST https://api.zoom.us/v2/chat/users/me/messages
• Scopes: chat_message:write, chat_channel:read

Chatbot API (Bot-Level)

• Messages appear as sent by your bot
• Requires Client Credentials grant
• Endpoint: POST https://api.zoom.us/v2/im/chat/messages
• Scopes: imchat:bot (auto-added)
• Rich cards: buttons, forms, dropdowns, images

Prerequisites

System Requirements

• Zoom account
• Account owner, admin, or Zoom for developers role enabled
  • To enable: User Management → Roles → Role Settings → Advanced features → Enable Zoom for developers

Create Zoom App

1. Go to Zoom App Marketplace
2. Click Develop → Build App
3. Select General App (OAuth)

⚠️ Do NOT use Server-to-Server OAuth for a chatbot. S2S apps cannot enable the Team Chat chatbot/subscription feature. S2S can still call supported Team Chat admin REST APIs.

Need to create the General App by API or manifest? Use Marketplace app management first. It covers Team Chat manifest requirements such as imchat:bot, team_chat_subscription, slash_command.development_message_url, shortcut action_types, and app-owned client_credentials scopes. Select the user, admin, S2S, or chatbot variant from the Marketplace template selector.

Required Credentials

From Zoom Marketplace → Your App:

Credential	Location	Used By
Client ID	App Credentials → Development	Both APIs
Client Secret	App Credentials → Development	Both APIs
Account ID	App Credentials → Development	Chatbot API
Bot JID	Features → Chatbot → Bot Credentials	Chatbot API
Secret Token	Features → Team Chat Subscriptions	Chatbot API

See: Environment Setup Guide for complete configuration steps.

Quick Start: Team Chat API

Send a message as a user:

// 1. Get access token via OAuth
const accessToken = await getOAuthToken(); // See examples/oauth-setup.md

// 2. Send message to channel
const response = await fetch('https://api.zoom.us/v2/chat/users/me/messages', {
  method: 'POST',
  headers: {
    'Authorization': `Bearer ${accessToken}`,
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    message: 'Hello from CI/CD pipeline!',
    to_channel: 'CHANNEL_ID'
  })
});

const data = await response.json();
// { "id": "msg_abc123", "date_time": "2024-01-15T10:30:00Z" }

Complete example: Send Message Guide

Quick Start: Chatbot API

Build an interactive chatbot:

// 1. Get chatbot token (client_credentials)
async function getChatbotToken() {
  const credentials = Buffer.from(
    `${CLIENT_ID}:${CLIENT_SECRET}`
  ).toString('base64');
  
  const response = await fetch('https://zoom.us/oauth/token', {
    method: 'POST',
    headers: {
      'Authorization': `Basic ${credentials}`,
      'Content-Type': 'application/x-www-form-urlencoded'
    },
    body: 'grant_type=client_credentials'
  });
  
  return (await response.json()).access_token;
}

// 2. Send chatbot message with buttons
const response = await fetch('https://api.zoom.us/v2/im/chat/messages', {
  method: 'POST',
  headers: {
    'Authorization': `Bearer ${accessToken}`,
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    robot_jid: process.env.ZOOM_BOT_JID,
    to_jid: payload.toJid,           // From webhook
    account_id: payload.accountId,   // From webhook
    content: {
      head: {
        text: 'Build Notification',
        sub_head: { text: 'CI/CD Pipeline' }
      },
      body: [
        { type: 'message', text: 'Deployment successful!' },
        {
          type: 'fields',
          items: [
            { key: 'Branch', value: 'main' },
            { key: 'Commit', value: 'abc123' }
          ]
        },
        {
          type: 'actions',
          items: [
            { text: 'View Logs', value: 'view_logs', style: 'Primary' },
            { text: 'Dismiss', value: 'dismiss', style: 'Default' }
          ]
        }
      ]
    }
  })
});

Architecture Patterns

Chatbot Lifecycle

User types /command → Webhook receives bot_notification
                            ↓
                     payload.cmd = "user's input"
                            ↓
                     Process command
                            ↓
                     Send response via sendChatbotMessage()

LLM Integration Pattern

case 'bot_notification': {
  const { toJid, cmd, accountId } = payload;
  
  // 1. Call your LLM
  const llmResponse = await callClaude(cmd);
  
  // 2. Send response back
  await sendChatbotMessage(toJid, accountId, {
    body: [{ type: 'message', text: llmResponse }]
  });
}

See: LLM Integration Guide

Common Operations

Send Message to Channel

// Team Chat API
await fetch('https://api.zoom.us/v2/chat/users/me/messages', {
  method: 'POST',
  headers: { 'Authorization': `Bearer ${token}` },
  body: JSON.stringify({
    message: 'Hello!',
    to_channel: 'CHANNEL_ID'
  })
});

Handle Button Click

// Webhook handler
case 'interactive_message_actions': {
  const { actionItem, toJid, accountId } = payload;
  
  if (actionItem.value === 'approve') {
    await sendChatbotMessage(toJid, accountId, {
      body: [{ type: 'message', text: '✅ Approved!' }]
    });
  }
}

Verify Webhook Signature

function verifyWebhook(req) {
  const message = `v0:${req.headers['x-zm-request-timestamp']}:${JSON.stringify(req.body)}`;
  const hash = crypto.createHmac('sha256', process.env.ZOOM_VERIFICATION_TOKEN)
    .update(message)
    .digest('hex');
  return req.headers['x-zm-signature'] === `v0=${hash}`;
}

Deployment

ngrok for Local Development

# Install ngrok
npm install -g ngrok

# Expose local server
ngrok http 4000

# Use HTTPS URL as Bot Endpoint URL in Zoom Marketplace
# Example: https://abc123.ngrok.io/webhook

Production Deployment

See: Deployment Guide for:

• Nginx reverse proxy setup
• Base path configuration
• OAuth redirect URI setup

Limitations

Limit	Value
Message length	4,096 characters
File size	512 MB
Members per channel	10,000
Channels per user	500

Security Best Practices

1. Verify webhook signatures - Always validate using x-zm-signature header
2. Sanitize messages - Limit to 4096 chars, remove control characters
3. Validate JIDs - Check format: user@domain or channel@domain
4. Environment variables - Never hardcode credentials
5. Use HTTPS - Required for production webhooks
