# Reply to Little Hotelier guest messages with an AI agent

> Answer WhatsApp, Airbnb and Booking.com guest questions in the Little Hotelier Messaging hub, with each booking checked before the reply.

Questions about late check-in, parking and breakfast land in the Messaging hub from WhatsApp, Airbnb and Booking.com, often after reception closes. Each answer needs a look at the booking first, and WhatsApp and Booking.com both run a 24-hour clock on the reply.

Cotlet does it in your own Little Hotelier account with list\_conversations, get\_reservation and reply\_to\_guest, called by your AI agent, an n8n workflow or a script.

## Can Little Hotelier do this on its own?

Little Hotelier has no API for properties (checked 11 Oct 2026). Guest Engagement sends scheduled messages before, during and after a stay, and the digital Concierge's guest directory covers fixed facts such as check-in times and parking. Nothing in Little Hotelier reads an incoming question and answers it; the AI chatbot plug-ins it lists (HiJiffy, Book Me Bob) sit on the booking engine and need their own account (help centre checked 12 Oct 2026).

By hand

## How you do it in Little Hotelier today

1. Open Guest Engagement > Communication > Messaging hub, or tap the messaging icon on the Home screen of the Little Hotelier mobile app.
2. Open the conversation and read the guest profile and reservation details that the Messaging hub links beside it before answering.
3. Reply in the thread; on WhatsApp, once 24 hours have passed since the guest's last message, pick an approved template from Guest Engagement > Communication > Settings > WhatsApp > Templates instead.
4. On Booking.com threads that need no answer, click the No reply needed icon so the conversation stops counting against your reply score.
5. Check your own inbox and your Twilio number for email and SMS replies, which the Messaging hub does not show.
6. The same handful of questions arrives every day, and a thread left past its window means a paid WhatsApp template or a slower Booking.com reply record.

With an agent

## How to reply to Little Hotelier guest messages with an AI agent

Prompt

```
Answer guest questions in the Messaging hub about late check-in, parking and breakfast using our house rules, and send me anything else.
```

1. 01  
### Pick threads that wait for you  
The agent calls list\_conversations and keeps the threads where the guest wrote last. Threads where your property or a scheduled message had the last word are skipped.
2. 02  
### Read the booking before answering  
For each linked reservation it calls get\_reservation, so "can we arrive at 23:00?" is answered against the real check-in date, room and guest comments.
3. 03  
### Answer only from your house rules  
Replies come from the rules you give the agent: reception hours, parking, breakfast price, pets. A complaint, a refund, a date change or anything outside the rules is not answered; it comes to you with a suggested reply.
4. 04  
### Respect each channel's window  
A WhatsApp thread more than 24 hours past the guest's last message gets no free-form reply; the agent names the template you would need. Airbnb threads open only after the guest answered a scheduled message. Booking.com threads come back as drafts to send in the hub, oldest first.
5. 05  
### Send with your OK  
reply\_to\_guest sends each answer after you approve it. You can switch approval off for the question types you trust the rules with, and keep it on for the rest.

### What you get back

Example data

```
Messaging hub: 6 threads waiting for you
Sent: Marta Kowal, WhatsApp, LH48213, late check-in at 21:30 is fine
Sent: Jonas Berg, Airbnb, free parking behind the building, no booking needed
Draft for you: Ana Ruiz, Booking.com, wants to move her stay to 14 to 16 Nov (date change)
Template needed: Liam Byrne, WhatsApp, last guest message 31 hours ago
Skipped: 2 threads where your scheduled check-in message was the last word
```

### Other ways to ask

- Every evening at 8, answer guest questions about parking and breakfast and send me everything else.
- WhatsApp only: list threads whose 24-hour window closes in the next 3 hours.
- Draft replies to all Booking.com messages from guests arriving this week, and send nothing.

Before you automate it

## What Little Hotelier allows, and what to know first

- Little Hotelier connects WhatsApp through the WhatsApp Business API: free-form replies are free within 24 hours of the guest's last message, after that only an approved template can go out, billed by WhatsApp at about USD 0.01 to 0.04 per conversation depending on category and the guest's country.
- WhatsApp reviews each Little Hotelier message template, which can take up to 24 hours, so a template cannot be created and used for the same overdue reply.
- A Booking.com conversation in the Little Hotelier Messaging hub has a 24-hour response window, and the No reply needed icon keeps a closed thread from affecting the reply score.
- The Little Hotelier Messaging hub shows email as view-only, and guest replies by email or SMS go to your inbox or Twilio number instead of the hub.
- Little Hotelier cannot send post-stay feedback messages through the Messaging hub for Airbnb and Booking.com guests, because of those channels' policies.

reply\_to\_guest asks for your OK by default. To run it daily without you, switch confirmation off for that tool in your dashboard.
