+title: Webex
+description: Connect Moltbot to Cisco Webex for enterprise messaging
+---
+
+# Webex Integration
+
+Connect Moltbot to [Cisco Webex](https://www.webex.com/) to enable AI-powered conversations in your enterprise messaging environment.
+
+## Prerequisites
+
+- A Webex account with bot creation permissions
+- A publicly accessible URL for webhook delivery (your gateway URL)
+
+## Setup
+
+### 1. Create a Webex Bot
+
+1. Go to the [Webex Developer Portal](https://developer.webex.com/my-apps)
+2. Click **Create a New App**
+3. Select **Create a Bot**
+4. Fill in the bot details:
+   - **Bot Name**: A display name for your bot
+   - **Bot Username**: A unique identifier (e.g., `moltbot`)
+   - **Icon**: Upload an avatar for your bot
+   - **Description**: A brief description
+5. Click **Create Bot**
+6. **Important**: Copy the **Bot Access Token** - you'll need this for configuration
+
+### 2. Configure Moltbot
+
+Run the setup wizard:
+
+```bash
+moltbot channels setup webex
+```
+
+Or configure manually:
+
+```yaml
+channels:
+  webex:
+    enabled: true
+    botToken: "YOUR_BOT_ACCESS_TOKEN"
+    webhookSecret: "your-webhook-secret"  # Create a strong secret
+    webhookPath: "/webex"  # Default webhook endpoint
+```
+
+### 3. Create a Webhook
+
+1. Go to [Webex Webhooks](https://developer.webex.com/docs/webhooks)
+2. Create a webhook with these settings:
+   - **Target URL**: `https://your-gateway-url.com/webex`
+   - **Resource**: `messages`
+   - **Event**: `created`
+   - **Secret**: Use the same `webhookSecret` from your config
+
+You can also create webhooks programmatically:
+
+```bash
+curl -X POST https://webexapis.com/v1/webhooks \
+  -H "Authorization: Bearer YOUR_BOT_TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "name": "Moltbot Messages",
+    "targetUrl": "https://your-gateway-url.com/webex",
+    "resource": "messages",
+    "event": "created",
+    "secret": "your-webhook-secret"
+  }'
+```
+
+### 4. Add Bot to Spaces
+
+1. In Webex, open a space or create a new one
+2. Click the **People** icon
+3. Add your bot by its email address (shown after setup)
+4. The bot will now receive messages in that space
+
+## Configuration
+
+### Full Configuration Reference
+
+```yaml
+channels:
+  webex:
+    enabled: true
+
+    # Authentication
+    botToken: "YOUR_BOT_ACCESS_TOKEN"     # Required
+
+    # Webhook settings
+    webhookSecret: "your-webhook-secret"  # Required for security
+    webhookPath: "/webex"                 # Default: /webex
+    webhookUrl: "https://..."             # Optional: explicit webhook URL
+
+    # Bot identification (auto-detected if not set)
+    botId: "Y2lz..."                      # Optional: for precise @mention detection
+    botEmail: "bot@webex.bot"             # Optional: bot's email address
+
+    # DM policy
+    dm:
+      policy: "pairing"                   # open, pairing, allowlist, disabled
+      allowFrom:
+        - "user@example.com"
+        - "Y2lzY29..."  # Person ID
+
+    # Group/room policy
+    groupPolicy: "allowlist"              # open, allowlist, disabled
+
+    # Room-specific configuration
+    rooms:
+      "ROOM_ID_HERE":
+        allow: true
+        requireMention: true              # Only respond when @mentioned
+        systemPrompt: "Custom prompt for this room"
+        users:                            # Optional: restrict to specific users
+          - "user@example.com"
+```
+
+### DM Policies
+
+| Policy | Description |
+|--------|-------------|
+| `open` | Anyone can DM the bot (use with caution) |
+| `pairing` | New users must be approved before chatting |
+| `allowlist` | Only users in `dm.allowFrom` can chat |
+| `disabled` | No DMs allowed |
+
+### Group Policies
+
+| Policy | Description |
+|--------|-------------|
+| `open` | Bot responds in any space it's added to (mention-gated) |
+| `allowlist` | Only configured rooms in `rooms` section |
+| `disabled` | No group messages processed |
+
+## Environment Variables
+
+For the default account, you can use environment variables:
+
+| Variable | Description |
+|----------|-------------|
+| `WEBEX_BOT_TOKEN` | Bot access token |
+| `WEBEX_BOT_ID` | Bot's person ID |
+| `WEBEX_BOT_EMAIL` | Bot's email address |
+
+## Multi-Account Support
+
+Run multiple Webex bots with named accounts:
+
+```yaml
+channels:
+  webex:
+    enabled: true
+    defaultAccount: "support"
+    accounts:
+      support:
+        name: "Support Bot"
+        botToken: "TOKEN_1"
+        webhookSecret: "secret1"
+        webhookPath: "/webex/support"
+      internal:
+        name: "Internal Bot"
+        botToken: "TOKEN_2"
+        webhookSecret: "secret2"
+        webhookPath: "/webex/internal"
+```
+
+## Status & Troubleshooting
+
+Check connection status:
+
+```bash
+moltbot channels status --probe
+```
+
+### Common Issues
+
+#### Bot not receiving messages
+
+1. Verify webhook is configured correctly in Webex
+2. Check that webhook secret matches your config
+3. Ensure gateway is accessible from the internet
+4. Check gateway logs for webhook errors
+
+#### Authentication errors
+
+1. Verify bot token is valid: `moltbot channels status webex --probe`
+2. Regenerate token if expired (tokens don't expire but can be revoked)
+
+#### @mention not detected
+
+1. Ensure `botId` is configured (auto-detected on first probe)
+2. In group spaces, bot typically requires @mention to respond
+
+## API Limits
+
+- **Message length**: 7,000 characters (markdown)
+- **File attachments**: Webex handles file URLs directly
+- **Rate limits**: Webex has rate limits; the plugin handles retries
+
+## Security Notes
+
+- **Webhook secret**: Always use a strong, random secret for webhook verification
+- **Token security**: Store bot tokens securely; never commit to version control
+- **DM policy**: Use `pairing` or `allowlist` in production to control access
