What is Online Check-In
Online Check-In lets guests submit their details before they arrive at the property. You receive an automatic email notification as soon as a guest submits, and all data is available in the dashboard.
Enabling the feature
Online Check-In is enabled per tenant by an administrator. Once active, a Check-In Settings tab appears in Settings and an Online Check-Ins entry appears in the sidebar.
Per-property settings
Go to Settings → Check-In Settings to configure each property individually.
Basic options
| Setting | Description |
|---|
| Enable | Turns online check-in on or off for the property |
| Hours before | How many hours before the check-in date the form becomes available (1–720, default: 24) |
| Check-in from | Earliest arrival time shown to the guest |
| Check-in until | Latest arrival time shown to the guest |
| Require additional guests | When on, guests are prompted to provide names of accompanying guests |
Request options
Define up to 20 request options that guests can select (e.g. “Baby Cot”, “Parking Information”). If the list is empty, the app defaults are used.
Copy settings between properties
Use the Copy icon on any property and Paste on another to replicate settings quickly. The Paste to all button applies the copied settings to every property at once.
How guests receive the check-in link
The check-in link follows this format:
https://app.etherly.app/checkin/{channel}/{bookingId}
channel matches the booking source (e.g. airbnb, booking, direct) and bookingId is the unique booking ID in the system.
The check-in link requires no login. It is public but rate-limited, and only valid within the configured time window.
Access window
The form is accessible:
- Opens:
hoursBefore hours before the check-in date
- Closes: end of the check-in day (23:59:59)
Outside the window, or if the check-in has already been submitted, guests see an appropriate message.
Language support
The guest form automatically detects the guest’s browser language and displays in Greek if the browser is set to Greek, or English otherwise. A language toggle button is always visible in the header so guests can switch at any time.
Guests follow a step-by-step wizard:
- Welcome — Booking summary (property, dates, nights)
- Guest details — Phone number, country, identification type (Tax ID / Passport / National ID) and number
- Additional guests (if enabled) — Names of accompanying guests
- Arrival time — Select an arrival time and optionally a departure time
- Requests — Choose from your configured list and add free-text notes
- Review & Submit — Confirm details and accept the privacy policy
Security & privacy
- The identification number (Tax ID / Passport / National ID) is encrypted with AES-256-GCM before being stored in the database.
- On the public form, the guest’s name and phone are shown partially masked (e.g.
Di****is K*****is).
- Rate limiting: 20 GET/min per IP, 5 POST/10 min per IP, 3 POST/hour per booking.
