# /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.

## 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/

- Token URL: `https://zoom.us/oauth/token`
- If `/oauth/token` returns 404/HTML, use `https://zoom.us/oauth/token`.

## 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](https://marketplace.zoom.us/)
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:

| 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](concepts/environment-setup.md) for complete configuration steps.

## Quick Start: Team Chat API

Send a message as a user:

```javascript
// 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](examples/send-message.md)

## Quick Start: Chatbot API

Build an interactive chatbot:

```javascript
// 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

```javascript
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](examples/llm-integration.md)

## Common Operations

### Send Message to Channel

```javascript
// 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

```javascript
// 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

```javascript
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

```bash
# 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](concepts/deployment.md) 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

**See**: [Security Best Practices](concepts/security.md)

## Architecture Patterns

### Chatbot Lifecycle

```
User Action → Webhook → Process → Response
```

### LLM Integration Pattern

```
User Input → Chatbot receives → Call LLM → Send response
```

### Approval Workflow Pattern

```
Request → Send card with buttons → User clicks → Update status → Notify
```

## Common Use Cases

### Notifications
- CI/CD build notifications
- Server monitoring alerts
- Scheduled reports
- System health checks

### Workflows
- Approval requests
- Task assignment
- Status updates
- Form submissions

### Integrations
- LLM-powered assistants
- Database queries
- External API integration
- File/image sharing

### Automation
- Scheduled messages
- Auto-responses
- Data collection
- Report generation
