MEWS
MEWS is a cloud-based property management system designed for modern hotels and hostels that prioritize automation and guest-centric experiences. Known for its open API and robust integration ecosystem, MEWS offers tools for reservations, housekeeping, payments, and guest messaging in a single platform. Its focus on contactless check-in, real-time dashboards, and seamless third-party connectivity makes it ideal for tech-forward properties seeking operational efficiency and flexibility. MEWS empowers hotel teams to eliminate repetitive tasks and deliver exceptional service with minimal friction.

MEWS PMS Integration
With the MEWS integration, you connect your Mews property management system to your HolidayHero workspace. The integration pulls every Mews reservation on the services and channels you choose into HolidayHero, so the rest of your operation — messaging, tasks, smart devices, reporting — runs on the same set of bookings as your front desk. When a new reservation lands, the guest is automatically invited to the HolidayHero guest app.
Listings & channel filtering
Match each HolidayHero listing to a Mews resource (a single room/unit) or a Mews resource category (a room type). Use the resource category mapping when you let Mews assign the specific room at check-in; use the resource mapping when the room is fixed. Optionally restrict which reservations are imported by listing the exact channel manager names you want to allow.
Guest check-in sync (HolidayHero → MEWS)
When a guest completes their online check-in inside HolidayHero, their profile details and identity-document data are pushed back into the matched Mews customer record automatically. The integration uses Mews's modern identity-documents endpoints — the deprecated Customer.Passport field is not used.
What gets synced: name, email, phone, date of birth, nationality, sex, postal address, and the guest's passport / national ID / driver's license (number, issuance, expiry, issuing country). Each guest on a reservation is matched to the right Mews customer (by email → full name → primary guest fallback), so multi-guest bookings stay accurate.
The integration never overwrites a Mews field with an empty value. If HolidayHero doesn't have a value for a given field, that field is left untouched on the Mews customer record — so existing front-desk data stays safe.
Reservations tab
A dedicated Reservations tab inside the integration lists every reservation whose guest check-ins have been pushed to Mews. Each row shows a synced / total guests count, the last-synced timestamp, and direct deep-links into both HolidayHero and Mews. Click View to see exactly which guests are on file in Mews — pending or failed check-ins are deliberately hidden so the page reflects the real state of your Mews customer records.
Guides
How to integrate with mews?
In MEWS
Open the Mews Marketplace and request a Connector integration with HolidayHero.
Generate an Access Token for the integration.
Copy the Access Token.
In HolidayHero
Go to your desired HolidayHero Workspace.
Go to Integrations.
Select MEWS.
Walk through the authentication process. You are installing an application on top of your HolidayHero workspace.
Inside the MEWS integration, go to Settings.
Paste the Access Token.

Ho do I enable guest check-in sync back to MEWS?
First, ensure brand check-in is enabled. (Read More)
Open the MEWS integration in HolidayHero and go to Settings.
Switch on Sync guest check-in details back to Mews.
Pick a fallback sex for guests whose gender on HolidayHero is non-binary or unspecified. Mews only supports Male or Female, so this is the value used when the guest doesn't fit either. Leave it blank to keep the existing Mews value untouched in that case.
Hit Save.
From that point on, every completed (or updated) guest check-in in HolidayHero is pushed back to the matched Mews customer record automatically.
What happens if a check-in is deleted in HolidayHero?
The identity-document fields (passport number, issuance, expiration, issuing country) on the matching Mews customer are cleared. The Mews customer profile itself is not deleted — only the identity document data sourced from the deleted check-in is wiped.
How are guests to Mews customers on multi-guest reservations?
Each HolidayHero check-in is matched to a Mews customer in this order:
By email (case-insensitive) against the customers on the Mews reservation.
By first + last name match.
For the primary guest only: fall back to the reservation's main Mews
CustomerId.
If none of these resolve, the integration logs a skipped activity entry on the Logs tab and does not overwrite any Mews customer.
Can I see what has been synced?
Yes. The Reservations tab inside the integration shows every reservation with at least one synced check-in, a synced / total counter, and a detail view that lists only the guests actually on file in Mews. Every sync (success, skip, failure) is also recorded on the Logs tab.
What if Mews returns a temporary error?
Transient API errors (timeouts, gateway errors, 5xx responses) are retried automatically by the queue before being marked as failed. Permanent errors are written to the Logs tab with the Mews response, so you can investigate.
