openclawor your preferred profile)
Note: Replace profile=openclaw in examples with your preferred browser profile if different.
Quick Reference
| Action | Command |
|---|---|
| Open pairing page | browser action=open profile=openclaw targetUrl="https://messages.google.com/web/authentication" |
| Check session | browser action=snapshot profile=openclaw โ look for conversation list vs QR code |

browser action=screenshot profile=openclawUser scans with phone:
- Open Google Messages app on Android
- Tap โฎ menu โ "Device pairing" โ "QR code scanner"

Important: Enable "Remember this computer" to persist the session.

browser action=act profile=openclaw request={"kind": "click", "ref": "<send_ref>"}
Receiving Messages (Real-time Notifications)
This skill includes a webhook system for real-time incoming SMS notifications.

node <skill>/sms-webhook-server.jsInject observer into browser (see
references/observer-injection.md)
Systemd Service (Persistent)
cp <skill>/systemd/google-messages-webhook.service ~/.config/systemd/user/
# Edit service file: set SMS_NOTIFICATION_TARGET in Environment=
systemctl --user daemon-reload
systemctl --user enable --now google-messages-webhook
Reading Messages
See references/snippets.md for JavaScript snippets to:

- Check session status
Troubleshooting
| Problem | Solution |
|---|---|
| QR code shown | Session expired, re-pair |
| Elements not found | Google updated UI, check snapshot for new selectors |
| Send button disabled | Message input empty or phone disconnected |
| Observer not detecting | Check browser console for [SMS Observer] logs |
| Webhook not receiving | Verify server running: curl http://127.0.0.1:19888/health |
Selectors Reference
Google Messages uses Angular components. These may change with updates.
| Element | Selector |
|---|---|
| Conversation list | mws-conversations-list |
| Conversation item | mws-conversation-list-item |
| Message input | textarea[aria-label*="message"] |
| Send button | button[aria-label*="Send"] |
| QR code | mw-qr-code |
Limitations
- Phone must be online (messages sync through phone)
- Browser tab must stay open for notifications
- Session expires after ~14 days of inactivity
- Observer lost on page reload (re-inject needed)
Security
- Webhook listens on localhost only (127.0.0.1)
- No credentials stored (session in browser cookies)
- QR pairing links to your phone โ treat as sensitive
