Hostaway bookings with WhatsApp confirmation and reminder
When a booking is confirmed in Hostaway, ChatSales messages the guest on WhatsApp with the property, arrival date and check-in time. 24 hours before check-in it sends a reminder.
WhatsAppHi Ana, your booking at Casa del Mar Tulum is confirmed: you arrive Friday, October 17 (check-in 3:00 pm). We're writing from Sol Stays; if you have questions, reply to this message.

What it does and doesn't do
| ✅ It can | 🚫 It can't |
|---|---|
| Confirm every new booking on WhatsApp: property, arrival date and check-in time. | Message guests with no phone on the booking (some channels hide it). |
| Remind the guest 24 hours before check-in, in the property's time zone; if the stay moves, the reminder moves with it. | Write about inquiries, pending requests, owner stays or cancelled bookings. |
| Register the webhook in Hostaway for you (nothing to paste) and remove it if you disconnect. | Change bookings, prices or calendars: it only reads them and manages its own webhook. |
| Write without Meta-approved templates (Utility category). |
🔐 A Hostaway API key gives access to the account. ChatSales stores it encrypted and only uses it to read bookings and listings and to create or remove its webhook. You can delete the key any time in Hostaway; it then stops working here.
Set up in 3 steps
- Turn on Hostaway in the ChatSales App Store.
- Paste your Hostaway Account ID and API key: ChatSales registers its own webhook in your account, nothing to paste in Hostaway.
- Review the messages and switch off any you don't want.
The message your customer gets
ChatSales creates this template in Mexican Spanish and submits it to Meta; here is what it says, in English (you can pick another approved flow):
What you need
You need:
A WhatsApp API number connected in ChatSales (Connect your WhatsApp). These messages are the first contact with someone who has not written to you, so WhatsApp only allows them with a Meta-approved template.
To be an admin of your ChatSales team and have access to your Hostaway account.
Rules that protect your number
Numbers without a country code: your guests come from many countries, so by default we only message numbers with "+code". If nearly all your guests are from Mexico, you can turn it on under Connection.
