Portugal requires hosts to register guests with the SIBA portal (Sistema de Informação de Boletins de Alojamento). With Holidu's Online Check-in feature, you can collect your guests' details automatically and send them to SIBA, which helps you meet local registration rules. This guide explains how to connect your Holidu account to SIBA, how the process works for you and your guests, and how to resolve common issues. Holidu helps with collecting and transferring guest data, but legal compliance remains the host's responsibility.

Before You Start: What Are the Prerequisites?

Before you activate Online Check-in with SIBA, make sure your property is registered on the official SIBA portal and that you have your SIBA credentials ready. You also need to know which submission method is active in your SIBA account.

• You already have a property registered on the official SIBA portal at https://siba.ssi.gov.pt.
• You have the following SIBA credentials available:
  • NIF of the Hotel Unit (Unidade Hoteleira)
  • Establishment Code (Estabelecimento)
  • Authentication Key (Chave de Ativação), usually a 12-digit password. These are the same credentials you use to access the official SIBA portal.
• You know which bulletin submission method (Método de envio) is active in your SIBA account. Holidu supports two methods: "SEF-SIBA web service integration" and "SEF-SIBA Página no portal integration". The method you select in Holidu must match the one configured in SIBA.
• You can check the current submission method by logging in to the SIBA portal at https://siba.ssi.gov.pt/s/an/default.aspx. If you need to change it and cannot do so yourself, contact SIBA directly at https://siba.ssi.gov.pt/contactos.

How to Configure Guest Online Registration Between Holidu and SIBA

To connect SIBA, go to Online Check-in in your Holidu app, select the property, and enter your SIBA details. Choose the sending method that matches your SIBA account, validate the connection, and save your changes.

1. In your Holidu app, go to "Bookings" in the left-side menu and click "Online Check-in".
   
2. You will see a list of your properties. Click "Configure" next to the property you want to connect.
3. Complete the property information form.
   
4. Fill in the form with your information and SIBA credentials, and turn on "Send data automatically to the responsible authority".
   
5. Select the sending method. For Portugal, there are two options, and each one requires different fields:
   • SEF-SIBA web service integration (see Option A below)
   • SEF-SIBA Página no portal integration (see Option B below)
   Always choose the option that matches the sending method (Método de envio) configured in your SIBA account. If they do not match, validation and data transfer will fail.
6. Complete the fields for your selected method.
   

Option A: SEF-SIBA Web Service Integration

Use the same credentials you use to log in to the SIBA portal. The Método de envio in your SIBA account must be set to "Web Service" for this option to work.

The required login fields are:

For the remaining fields (postal code, postal area, contact name, email and phone number), enter exactly the same information that appears in your SIBA account under "Atualização dos dados de inscrição" at https://siba.ssi.gov.pt/S/au/DadosIdentificacaoActualizacao.aspx.

Option B: SEF-SIBA Página no Portal Integration

Use the same SIBA login credentials. Only select this option if "Página no portal" is the sending method set in your SIBA account. You can verify this under "Atualização dos dados de inscrição" in the SIBA portal.

The required fields are:

This option does not require address or contact details. You only need the three fields above.

How to Switch Between the Two Methods

The sending method in the Holidu app must always match the Método de envio in your SIBA account. Changing it in Holidu alone is not enough. You must request the change from S
