Integrations
Connect once. Keep your systems.
Ersona works across the systems your hotel already uses — to understand what is happening and to carry out the work you approve. Your PMS stays the system of record.

More hotel systems, same idea.
Ersona picks up the reservation and guest context it needs, and runs the conversation on your channels.
Guest channels
Wherever the guest writes from.
Every channel lands in the same conversation view with the same guest context — and each one can follow its own rules for what Ersona handles, when it escalates and who it hands to.
- WhatsApp BusinessMeta Business Messaging Tech Provider
Guests message your number; Ersona replies with reservation context, sends approved templates on journey steps (pre-arrival, check-in, in-stay, post-stay) and hands over to a person when needed.
- VoiceInbound · Outbound · Routing
Ersona answers the phone with the reservation in view and in the caller’s language, calls guests back when a journey step or a task needs it, and routes to the right person when your rules say a human should take it.
- Email
Inbound guest email is handled like any other conversation; journey emails go out from your templates.
- Website chat
Pre-booking questions answered on your site, with a path to your booking engine and to your team.
- OTA inboxes (Airbnb, Booking.com)
Handled by Ersona through your Hostaway or Guesty connection, with the booking source shown on every thread.
Available with Hostaway and Guesty today.
Booking and payments
Where intent becomes a booking.
A conversation is only worth having if it can finish. Ersona carries booking intent to your own engine and takes payment on a secure checkout — the reservation and the money land in your systems, the way they do today.
- Booking engine
In website chat and WhatsApp, Ersona takes booking intent to your booking engine — the Hostaway or Guesty engine, or your own booking URL — instead of leaving the guest to search elsewhere.
The booking is created by your engine and lands in your PMS as usual.
- WebHotelier
Ersona connects to WebHotelier so conversations carry the reservation and rate context that lives there, and booking intent goes to your own WebHotelier engine.
Bookings, rates and availability stay in WebHotelier.
- Payments (hosted checkout)
Guests pay for eligible products and services on a secure checkout — late checkout, early check-in, spa and partner services — with approval by your team where you want it.
Your merchant relationship and settlement.

Questions
Something not answered here? Write to us
Which PMS systems are supported?
Hostaway and Guesty are connected end to end, including their guest inboxes. Optima, Cloudbeds and MiniHotel provide the reservation and room data behind conversations on Ersona’s own channels. We add integrations based on customer demand.
What data is synced?
Listings and rooms, reservations, guest profiles and — with Hostaway and Guesty — the guest inbox, so every conversation carries the right context.
How long does integration take?
It depends on the PMS. You provide API credentials and we set up and test the connection together — usually well within your first week.
What if my PMS isn’t listed?
Contact us. If your PMS has an API, we can likely build the integration. Custom integrations are available for enterprise clients.
Is my data secure?
Data is encrypted in transit and at rest. See our privacy policy for how we handle data.
Not sure how your stack fits?
Tell us what you run. We’ll show you what Ersona would connect to and what it would leave exactly where it is.
