Using Make.com for Hotel PMS & Smart Lock Integration and Whatsapp Meesage to Customer?

Beginner Questions
1

Hello,

We are evaluating Make.com for a hotel automation use case and would like to confirm if our scenario is supported.

Our use case is:

  • a hotel PMS (no public API) that sends automatic system emails or exports reservation data,

  • smart locks with an API (PIN codes / mobile keys),

  • and optional WhatsApp notifications to guests.

We would like to use Make.com to:

  • trigger scenarios based on incoming reservation / check-in / check-out emails,

  • extract data (guest, room, check-in/check-out dates),

  • create and deactivate PIN codes via the smart lock API,

  • and send messages (e.g. WhatsApp) at a scheduled time (e.g. 1 day before check-in).

Could you please confirm:

  1. Is email-based triggering (IMAP/Gmail) suitable and supported for this use case?

  2. Can Make.com delay or schedule actions based on dates contained in the email?

  3. Is it supported to call external REST APIs (smart lock providers) using the HTTP module?

  4. Are there any limitations or best practices we should be aware of for this scenario?

Thank you in advance.

Kind regards,
Oliver Schultze

Hey Oliver,

  1. The custom mailhook module is used to trigger a scenario when a new email arrives. But are you sending or receiving the emails?
  2. You want one of the scenarios to execute based on a date in one of the emails? You will need an external database for this. Somewhere to store said dates and send triggers to Make to start the scenario. This could be a google sheet for example, if you are not using something like Monday, Notion, Airtable, ClickUp already.
  3. Yes.
  4. There may be, depending on your first and second question.

What PMS and smart locks are you using in particular? You can do pretty much anything with email triggers, scheduled actions or delays, and Webhook/API calls.

The main thing you need to watch out for is sending duplicate PINs or messages for the same booking.

This is based on my experience with this kind of setup.
