FAQs

Who can benefit from using FLEXIPASS APIs?

FLEXIPASS is designed for:

PMS and channel manager developers
Guest communication or concierge app builders
Hotel tech startups and integrators
Hospitality platforms offering self-check-in or automation

Do guests need to download an app to use FLEXIPASS keys?

No app required! Guests can access their digital keys via WebKeys (browser access) or Wallet Keys (Apple/Google Wallet). For hotel apps, developers can also integrate Mobile Keys directly for an in-app experience.

What is the FLEXIPASS API?

The FLEXIPASS API is a suite of developer tools that enables digital hotel key integration into any system — from Property Management Systems (PMS) to guest apps or self-check-in platforms. With one API connection, you can issue, manage, and revoke Mobile Keys, WebKeys, and Wallet Keys securely and instantly.

How does FLEXIPASS improve the guest experience?

FLEXIPASS enables frictionless, app-free digital access, eliminating physical key cards and reducing front-desk wait times. Guests enjoy fast check-in, secure entry, and modern convenience — all through a personalized digital experience.

Can I use FLEXIPASS if the guest’s phone is offline?

Yes. Mobile Keys and Wallet Keys can operate in offline mode using secure cryptographic tokens stored locally on the device. Once the key is downloaded or provisioned, guests can unlock doors without internet access which is ideal for low-connectivity environments.

How can I delete or update a mobile key?

Using the FLEXIPASS API, you can delete, update or issue a new mobile key in real time. Simply call the respective endpoint (e.g., /deleteMobileKey or /updateMobileKey) with the key ID. The system instantly synchronizes changes across all connected locks and user devices.
