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.

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/...

1. 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.

Having issues?

• 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?

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 - S2S apps don't have the Chatbot/Team Chat feature. Only General App (OAuth) supports chatbots.

Required Credentials

From Zoom Marketplace → Your App:

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

Sample Applications

See: Sample Applications Guide for analysis of all 10 samples

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

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
