From a Guestline reservation to a conversation
chatlyn keeps in step with Guestline. Nothing is exported, nothing is typed twice, and Guestline stays the system of record.
Messages triggered by Guestline use your hotel’s default language, and the AI replies in whichever language the guest writes.
Every Rezlynx event can start a WhatsApp message
Created, changed, cancelled, checked in, checked out or no-show: each Guestline event can trigger the next message of your guest journey, with the guest’s name, dates and room filled in from the reservation. A cancellation stops the messages that no longer apply.
chatlyn syncs with Rezlynx every few minutes, so the booking confirmation follows shortly after the reservation and every later message leaves at the time you set. Build the timing once in guest journey automation.
The Guestline stay, beside every conversation
When a guest writes on WhatsApp, email, your website chat or Booking.com, the conversation sits on one guest profile with their stays from Guestline: dates, room and booking reference.
Your team answers without switching to Rezlynx, and the guest never has to repeat their booking number. Across a hotel group, each property keeps its own reservations and conversations.
The AI answers, your team takes the rest
chatlyn’s AI answers on WhatsApp, your website chat and newly created Booking.com inboxes, from your own knowledge and in the guest’s language. On email it drafts the reply and your team sends it.
Anything personal goes to a colleague with the whole conversation, translated both ways. It is the same AI as the hotel chatbot.
Segments from Guestline data, offers on WhatsApp
Because every stay comes from Guestline, you can pick guests by arrival date, length of stay or room, and send a WhatsApp offer to those who opted in: dinner on the first night, the spa before arrival, a late check-out.
Guests reply or tap to book, and the conversation stays on their profile. More on the whole hotel guest experience software.

Questions about the Guestline integration.
chatlyn syncs with Guestline Rezlynx every few minutes and picks up every reservation that was created, updated, cancelled, checked in, checked out or marked as a no-show. It stores the reservation with the booker, the stay and the room. Your guest journeys and segments run on that data, and every conversation shows the stay.
Within a few minutes. A booking confirmation goes out shortly after the reservation is made in Rezlynx, and pre-arrival, check-in and post-stay messages leave at the times you set in the journey.
Reservation created, updated, cancelled, checked in, checked out and no-show. Each can start the next message of a journey, and a cancellation stops the messages that no longer apply.
Your hotel’s default language, which you set in chatlyn. When the guest replies, the AI answers in the language they write in, and your team sees every message translated both ways.
Yes. The Guestline integration supports multi-property groups, and each property keeps its own reservations, inboxes and guest journeys in chatlyn.
chatlyn reads from Guestline, and Guestline stays your system of record for reservations, rates and payments. Rooms are booked in your booking engine, and requests from conversations go to your team.
You pay for chatlyn according to your plan, and WhatsApp conversation fees from Meta apply as on any WhatsApp Business account. Guestline may charge for the interface; we clarify it with you before you sign.
Guestline issues the credentials for the connection to your hotel, and our customer success team sets up the integration, your WhatsApp number and the first guest journeys with you. How long it takes depends mostly on WhatsApp template approval and on the journeys you want at the start.
One platform for every team, hotel and goal.
