What can you do with Mews on Tray.ai?
Mews is a hotel property management system covering reservations, guest profiles, billing, payments, rates, and room availability for hospitality businesses. Tray.ai connects to Mews through the HTTP Connector, so your workflows can call the Mews API alongside the rest of your stack. API access comes through Mews's partner program or API plan, so you need approved credentials first.
- When Mews sends “Customer added”, create the guest profile in your marketing platform.
- Add reservations to Mews from bookings taken by your group sales team.
- Get a bill PDF at checkout and file it with the guest's record in your accounting system.
- Update payment records in your finance system each time Mews sends “Payment updated”.

Set it up
Connect Mews to Tray.ai
Each step uses Mews's own API details, from its documentation.
Step 1
Save Mews's API key
Ask Mews for API access. Once it's approved, save the key as a Tray.ai authentication and add it to the request body from $.auth, so it never sits in the workflow itself.
Step 2
Point the HTTP Client at the API
Add an HTTP Client step and use https://api.mews-demo.com/api/connector/v1 as the base URL. Or paste a cURL example from Mews's API docs, and Tray.ai fills in the method, URL, and headers.
Step 3
Start with “Get all reservations”
It's one of 17 documented actions, under Reservations. The response comes back as data the next step can map into your other apps.
Step 4
Start workflows from Mews events
Give Mews the URL of a Tray.ai webhook trigger. “Service order updated” can then start a workflow, and so can 6 other events.
What the Mews API covers
