Connecting your Holidu account to SIBA (Sistema de Informação de Boletins de Alojamento) lets you collect guest details automatically and send them to the Portuguese authorities, so you can meet Portugal's local guest registration rules with less manual work. This guide explains the prerequisites, how to set up the connection, what guests see, what each form status means, and how to download the guest registration form (Boletim de alojamento).

Note: Holidu helps you collect and transfer guest data, but legal compliance remains the responsibility of the host. For full legal information, consult the official SIBA portal at https://siba.ssi.gov.pt.

Before You Start: What Are the Prerequisites for Connecting SIBA to Holidu?

Before you activate online guest registration in Holidu, make sure the following requirements are in place:

1. You already have a property registered on the official SIBA portal at https://siba.ssi.gov.pt.
2. You have your SIBA credentials available:
   • NIF of the Hotel Unit (Unidade Hoteleira)
   • Establishment Code (Estabelecimento)
3. You have your Authentication Key (Chave de Ativação), usually a 12-digit password. These credentials must be the same ones you use to access the official SIBA Portal.

1. You know which bulletin submission method (Método de envio) is active in your SIBA account. Two methods can be connected to Holidu: "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.
   • Log in to the SEF account at https://siba.ssi.gov.pt/s/an/default.aspx to check the current submission method.
   • If you need to change the submission method and cannot do it yourself, contact SIBA directly at https://siba.ssi.gov.pt/contactos.

How to Configure Online Guest Registration Between Holidu and SIBA

Follow these steps to connect a property to SIBA in your Holidu app.

1. In your Holidu app, go to Tools in the left-side menu and click Online Check-in.

1. You will see a list of your properties. Click Configure next to the property you want to connect.

1. Fill in the form with your property information and your SIBA Portal credentials, then enable Send data automatically to the responsible authority.

1. Select the sending method. For Portugal, choose the option that matches the Método de envio currently set in your SIBA account:
   • SEF-SIBA web service integration: see Option A below.
   • SEF-SIBA Página no portal integration: see Option B below.
   If the two methods do not match, validation and data transfer will fail.

Option A: SEF-SIBA Web Service Integration

Use the same credentials you use to access the SIBA portal at https://siba.ssi.gov.pt/S/FB.aspx.

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.

On that same SIBA page, the Método de envio must be set to Web Service for this option to work.

Option B: SEF-SIBA Página no Portal Integration

Use the same credentials you use to access the SIBA portal at https://siba.ssi.gov.pt/S/FB.aspx.

The required fields are:

No address or contact details are needed for this option. Only select "Página no portal" if it is the sending method configured in your SIBA account, which you can verify under Atualização dos dados de inscrição.

How to Switch Between the Two Methods

The sending method selected in Holidu must always match the Método de envio in your SIBA account. Changing it in Holidu alone is not enough. The change must be requested from SIBA.

1. Check the current method in the SIBA portal under Atualização dos dados de inscrição at https://siba.ssi.gov.pt/S/au/DadosIdentificacaoActualizacao.aspx.
2. If it is not the method you want, collect your NIF (your company
