Connect Guesty to WhatsApp, Instagram, TikTok and AI Chat

By Alva Chew 6 min read Updated October 30, 2026

Guests message you on WhatsApp, Instagram, Messenger, TikTok, Telegram, web chat or email, but your listings, calendar and reservations live in Guesty. AeroChat answers those conversations and works from Guesty as it goes: it checks the calendar, finds the reservation, creates the booking and logs the request for your team. It connects through Guesty’s public API. You describe the workflow in your own words, and AeroChat builds it.

What you can do with Guesty and AeroChat

  • Take direct booking enquiries in chat. AeroChat checks the listing calendar for the guest’s dates, quotes the stay and creates the reservation in Guesty.
  • Answer guest questions from the reservation. AeroChat finds the guest’s reservation and replies with their dates, check-in time and property details.
  • Log guest requests as tasks. When a guest asks for an early check-in, extra towels or a repair, AeroChat opens a task in Guesty for your team.
  • Recognise returning guests. AeroChat looks up the guest by phone or email and uses what Guesty already holds about their past stays.
  • Add notes to the reservation. AeroChat records arrival times, special requests and the guest’s questions on the reservation, so your team sees them.

Works on every chat channel

Your guests message you wherever they already are. The same Guesty connection and the same workflows run on every channel AeroChat supports, and Guesty stays the record whichever one they use.

Channel What your guests can do
WhatsApp Message your WhatsApp Business number to check dates, book a stay, ask about their reservation or request something for their stay. Voice notes are transcribed, so a spoken request works too.
Instagram Send the same requests by direct message. A comment on your post can get an automatic reply that moves the conversation to a DM.
Facebook Messenger Send the same requests to your Facebook Page. Comments on your Page posts can get an automatic reply too.
TikTok Send the same requests by TikTok direct message or TikTok Shop buyer chat. Both arrive in the same TikTok inbox.
Telegram Send the same requests to your business on Telegram.
Web chat Do the same from the chat on your website, without leaving the page.
Email Write to your Gmail or Office 365 address and get the same answer the chat gives.

How the connection works

AeroChat connects through Guesty’s public Open API. It reads listings, calendar availability, reservations and guests, and it can create reservations, add notes to them and open tasks. Each workflow uses only what its recipe asks for.

To connect, a Guesty admin opens Integrations, then Developer tools, and creates an OAuth application for AeroChat. Copy its client ID and client secret and paste them into the AeroChat dashboard when AeroChat asks. Guesty shows the secret only once, so copy it when you create the application. Your Guesty account needs API access for the option to appear.

You describe the workflow in your own words. AeroChat builds it as a draft, works out which Guesty calls it needs, and asks you to connect. Keys and credentials are entered in the AeroChat dashboard and never pass through the conversation.

Workflows to copy

Copy this into AeroChat

When a guest asks if a property is free, ask for their dates and number of guests. Check the listing calendar in Guesty. If the dates are free, reply with the total for the stay and our house rules. If not, offer our other listings that are free on those dates. When they want to book, ask for their full name, email and phone number and create a reservation in Guesty with the status Inquiry (example). Tell them our team will confirm and send the payment details within two hours (example).

Copy this into AeroChat

When a guest asks about their stay, find their reservation in Guesty by phone number, email or confirmation code. Reply with their check-in and check-out dates, our check-in time and the property address. If they ask for an early check-in, a late check-out or anything extra, create a task in Guesty on that reservation with their request and tell them our team will confirm. Never share details of a reservation unless the guest’s phone or email matches it.

Who uses it

Holiday rental managers, serviced apartment operators and small hotels that run their listings and channels in Guesty use it for guest messages before and during the stay. These recipes cover the same conversations:

What stays in Guesty

Guesty stays your record. Listings, rates, the multi-calendar, reservations, channel connections, payments and tasks live there, and your team still sets prices, confirms bookings and runs the turnovers.

AeroChat handles the conversation. It creates the reservations, notes and tasks your recipe asks for and leaves the rest to Guesty and your team.
