Who this stack is for
Resly operators that want AI guest support and partner coordination while keeping the PMS connection read-only.
The coordination problem
Resly can provide the room and reservation context, but guest and partner conversations may be spread between WhatsApp and email. Without a shared operational layer, staff still have to identify the stay, copy the property facts and remember to follow up across both channels.
The answer
One workflow, with clear system ownership
Proptonomy reads room types and reservations from Resly, then uses its own WhatsApp and Gmail connections for conversation and coordination. Resly stays read-only. The AI can answer from the stay context, dispatch work and keep chasing it without pretending the PMS has a messaging write-back it does not have.
Fast guest and partner conversations
Guests, cleaners and maintenance partners can be answered or briefed in their own language on the channel already on their phone.
How WhatsApp connectsEmail from the address guests already recognise
Gmail
Selected inbox threads are matched to the correct property and reservation, and approved replies leave from the connected Gmail address.
How Gmail connectsExample workflow
From incoming question to confirmed outcome
The stack matters only if the same operational record survives the handoff between tools and people.
- 1
A direct message arrives
The phone number, email address or booking reference is matched against the current Resly reservation so the AI can identify the stay.
- 2
The answer uses property and booking context
Dates, room type, arrival state and property knowledge are combined with the conversation instead of relying on a generic chatbot response.
- 3
Operational work is assigned
If the guest needs a person on site, the cleaner or vendor is briefed through WhatsApp or email and followed up against a task and deadline.
- 4
The original channel gets the update
The guest receives the completion message in WhatsApp or Gmail. The reservation context remains read-only in Resly.
Boundaries
What each tool continues to own
A trustworthy integration explains the non-goals as clearly as the data flow. These boundaries prevent duplicate records and unexpected writes.
Resly stays read-only
Room types and reservations sync into Proptonomy, but the AI does not edit those records or write a conversation back into Resly.
Messages use the connected channel
A WhatsApp message is answered on WhatsApp and a Gmail thread from the connected mailbox, preserving the conversation the guest sees.
Automation starts with drafts
New inboxes begin in observe mode. Your team reviews what would be sent and enables automatic replies only where it is comfortable.
Rollout
Connect, observe, then enable
The exact credentials differ by system, but the safe operating sequence stays the same.
- 1
Connect the sources
Connect Resly, WhatsApp, Gmail with the credentials or partner flow described on each integration page.
- 2
Confirm the matches
Check that properties, reservations, partner chats and external records resolve to the same operational entity before any write action is enabled.
- 3
Review observe-mode work
Let the AI read current traffic, draft answers and show proposed actions. Correct property knowledge and routing while nothing is sent automatically.
- 4
Enable one boundary at a time
Turn on the inboxes and actions the team trusts, while sensitive categories and less-tested properties remain behind approval.
FAQ
Resly + WhatsApp + Gmail FAQ
Direct answers, written to stand on their own in search and AI results.
Does Proptonomy write messages back to Resly?
No. The Resly connection is read-only for room types, reservations and calendar context. Guest conversations use connected Proptonomy channels such as WhatsApp and Gmail.
How does the AI match a WhatsApp guest to a Resly booking?
It first uses the guest phone number and current reservation data. If there is no confident match, it asks for a booking reference before using reservation-specific information.
Can replies come from our own Gmail address?
Yes. Connect the mailbox you want the operation to use. Proptonomy matches the thread to the reservation and sends approved replies from that address.
Can this workflow coordinate cleaners as well as guests?
Yes. A guest request can become a task and a partner brief on WhatsApp or email, with automatic follow-up until the partner confirms completion.
