# V5 — WhatsApp + Notifications

This release adds the communication layer to the V4 CRM.

## Environment

Set:
```env
WHATSAPP_PHONE_NUMBER_ID=
WHATSAPP_ACCESS_TOKEN=
```

## Features
- WhatsApp Cloud API outbound text service
- Message history and status tracking
- Lead-linked WhatsApp messages
- In-app notification log and read state
- CRM navigation for WhatsApp and notifications

The service fails safely when credentials are not configured; it does not silently claim a message was sent.

## Production notes
Configure the Meta WhatsApp Business assets, phone number, access token, HTTPS, and required Meta permissions before production use. Use templates where Meta requires templated messaging for the applicable conversation window/use case.
