Online Check-in (also called Advanced Check-in) lets you send guest registration data to your local authority automatically. To set it up, register your property with the authority in your country or region, then connect that registration to your Holidu account under Bookings, Online Check-in. Once connected, guests complete their details before arrival, and the data is submitted to the authority at 11:00 PM on the day of check-in.

1. Register with the responsible authority

Before you activate Online Check-in in Holidu, you must register your accommodation with the relevant local authority. This step is mandatory. The table below lists the supported countries and regions and the official registration portal and setup guide for each one.

After 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 your Holidu account in the next step.

2. Connect your property to the authority

When you have your authority credentials, follow these steps to connect your property in the Holidu app.

1. In the Holidu app, open the left side menu, click "Bookings", 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 authority.
   
3. A screen shows 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 the username, password, and other required credentials. Do not use your Holidu login here. Use the login credentials you received from your authority.
   
6. Click "Validate".
7. After the connection is validated, click "Save changes" at the end of the form.
8. If no error message appears, your property is connected to the responsible authority.
9. Close the form and check that the connection now shows as active.

To avoid errors during setup, check these three points:

• Use the correct host fiscal code. This is your ID number or, if you are not Spanish, your NIE.
• Enter your full ID or NIE number, including all zeros.
• Use the login credentials from your local authority, not your Holidu login.

3. How does Online Check-in work?

After setup, the process runs automatically. Guests complete their details before arrival, and the data is sent to the authority on the day of check-in.

3.1 The guest process

1. After the 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 be added.
3. The data is submitted securely and stored in the system.
4. If the guest does not complete the form, automatic reminders are sent. If the guest still does not respond, you can enter the data for them.

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

3.2 How to read the status in the Bookings section

Each booking shows a status in the booking details. Use the table below to understand each one.
