WhatsApp replies suddenly stop: disconnect, reconnect, and resync

Why this happens

Usually because the webhook subscription expired, the callback URL changed after a domain move, a new number was linked without disconnecting the old one, or Meta app permissions were revoked.

What Vareons does about it

The app provides a Resync webhooks button that re-subscribes and repairs the route through POST /api/whatsapp/subscribe-webhooks, a webhook health panel inside View details for diagnosis, a red Disconnect button with browser confirmation before linking a new number, and a redeploy-templates action for stale templates.

• apps.whatsapp.supported — WhatsApp Automation app: Available
• apps.marketplace.supported — Apps marketplace (install/open/uninstall): Available

Limitations

Resync cannot repair Meta-side revoked permissions; a fresh OAuth may be required. Messages missed during the outage are not received retroactively.
