# WhatsApp Business Integration

> Connect WhatsApp Business to Cendra to automate guest messaging for short-term rentals. Two-way messaging with AI-powered responses, reservation context, and upsell delivery via WhatsApp.

Cendra integrates with WhatsApp Business to enable two-way guest messaging with AI-powered responses. WhatsApp is the most popular communication channel for guest interaction in hospitality, and Cendra makes it fully automated.

## What You Can Do With WhatsApp in Cendra

* **Receive guest messages** in your unified inbox alongside Gmail and Outlook conversations
* **Respond automatically** using Cendra's AI agents, trained on your property's knowledge base
* **Send upsell offers** for early check-in, late checkout, and extras via WhatsApp at the right moment
* **Translate messages** — communicate with international guests in their preferred language
* **Share media** — send check-in instructions with photos, location pins, and documents

## How It Works

Cendra connects to WhatsApp via the WhatsApp Business API (not WhatsApp Web). This provides:

* **Reliable delivery** — messages sent through the official API, not screen scraping
* **Business identity** — guests see your business name and verified badge
* **Two-way messaging** — guests can initiate conversations and you can send proactive messages
* **Template messages** — pre-approved message templates for proactive outreach (check-in reminders, upsell offers)

## Guest Experience

When a guest messages your WhatsApp Business number:

1. The message appears in Cendra's unified inbox
2. Cendra matches the phone number to a reservation in your PMS
3. The AI generates a response using property knowledge and reservation context
4. Based on your automation level, the response is sent automatically or queued for review
5. The guest receives the reply on WhatsApp — they never know it's AI
