The Online Check-in feature in Holidu sends your guests' registration data to your local authority automatically, so you can meet legal requirements without filling in forms by hand. This guide explains how to register with the authority, connect your property, read booking statuses, download your guestbook, fill in guest data manually, and resend data when a submission fails.

Quick answer: how do I set up Online Check-in in Holidu?

First, register your accommodation with the local authority in your country or region and get your login credentials. Then go to Tools, select Online Check-in, click Configure next to your property, enter the country details, turn on automatic sending to police, and enter the authority credentials. Click Validate, then Save changes.

Step 1: Register with the responsible authority

Before you activate the feature in Holidu, you must register your accommodation with the relevant local authority. This step is mandatory. Use the table below to find the authority for your region and the guide that explains how to connect.

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

Step 2: How do I connect my property to the authority?

Follow these steps to link your property to the authority through Online Check-in.

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, click Activate automatic sending to police, and select the correct authority. Enter your username, password, and all required credentials. Do not use your Holidu login here. Use the login details you received from your authority.
   
6. Click Validate.
7. After the activation 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 the following 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 should now show as active.

Step 3: How does Online Check-in work?

After setup, the system works automatically. Guests complete their details, the data is stored securely, and it is sent to the authority on the night before arrival. You can follow each booking's progress 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 traveler, including a scan of a passport or ID card. Each person traveling with the guest must be registered.
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 fill in the data for them.

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

How do I read the status in the Bookings section?

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