The Online Check-in feature lets you send your guests' identity details to the local authority automatically, so you can meet your legal reporting duties without manual data entry. This guide explains how to register with the authority, connect your property in Holidu, understand how the process works, read booking statuses, and fix common problems.

Which authorities does Holidu support, and how do I register?

Before you activate Online Check-in in Holidu, you must register your accommodation with the responsible local authority for your country or region. Registration is mandatory. Use the table below to find the correct authority and the guide for connecting it.

Once you register, the authority gives you a username, a password, and in some cases a renter or accommodation code. You will enter these details in Holidu in the next step.

How do I connect my property to the authority with Online Check-in?

To connect a property, open Online Check-in from the Tools menu, select the property, and enter the login details you received from the authority. Then validate the connection and save your changes. If no error appears, the property is connected.

1. In the Holidu app, open the left side menu, click "Tools", and select "Online Check-in".
2. You will see your list of properties. Click "Configure" next to the property you want to connect to the police or authority.
3. A screen shows all your properties and the connection status of each one. Click the property you want to connect.
4. Complete the form with the details of the country where the property is located.
5. Scroll down and click "Activate automatic sending to police". Select the correct authority and enter your username, password, and all other required credentials. Do not use your Holidu login here. Use the login details you received from the authority.
6. Click "Validate".
7. After the validation succeeds, click "Save changes" at the end of the form.
8. If no error message appears, your property is connected to the responsible authority.
9. Check these points to avoid errors:
   • Use the correct host fiscal code. This is your ID number, or your NIE if you are not Spanish.
   • Enter your full ID or NIE number, including all zeros.
   • Use the login credentials from your local authority, not your Holidu login.
10. Close the form. The connection status now shows as active.

How does Online Check-in work after setup?

After setup, the system works automatically. Your guests receive a secure check-in link, they submit their details, and Holidu sends the data to the authority at 11:00 PM on the day of check-in. You can follow each booking's status in the Holidu app.

What is the process for the guest?

1. After booking, the guest receives an email or message with a link to a secure online check-in form.
2. The guest enters the details of every traveller and scans a passport or ID document. Each person travelling with the guest must complete this step.
3. The system submits the data securely and stores it.
4. If a guest does not complete the form, automatic reminders are sent. If the guest still does not respond, you can fill in the data for them.

At 11:00 PM on the day of check-in, the system automatically submits the guest data to the relevant authority.

How do I read the status in the Bookings section of the Holidu app?

Open the booking details to see the Online Check-in status. The status shows whether data is missing, waiting for transfer, transferred, or failed.

Status	Example
Started, but missing data
Guest data complete but not yet transferred (the check-in date is in the future)
