Connecting Holidu to SIBA (Sistema de Informação de Boletins de Alojamento) lets you collect your guests' registration details online and send them automatically to the Portuguese authority. This helps you meet Portugal's local guest registration rules, known as the Boletim de alojamento, without entering each guest manually. This guide explains the prerequisites, how to configure the connection, what guests see, what each form status means, and how to download the guest registration form.

Holidu helps you collect and transfer guest data, but legal compliance remains the host's responsibility. For full legal information, please consult the official SIBA portal.

1. Before You Start: What Are the Prerequisites?

Before you activate online guest registration in Holidu, make sure that the following requirements are met.

  • You already have your property registered on the official SIBA portal.
  • You have your 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. Both "SEF-SIBA web service integration" and "SEF-SIBA Página no portal integration" can be connected to Holidu, but the method you select in Holidu must match the one configured in SIBA.

To check your current submission method, log in to the SIBA portal at https://siba.ssi.gov.pt/s/an/default.aspx and review the settings under "Atualização dos dados de inscrição". If you need to change the method and cannot do it yourself, contact SIBA directly through their contact page.

2. How to Configure the Guest Online Registration Between Holidu and SIBA

To connect your property, go to the Online Check-in section in your Holidu app, select the property, and enter your SIBA details. The steps below walk you through the process.

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

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

  3. Fill in the form with your information and your SIBA credentials, and enable "Send data automatically to the responsible authority".

  4. Select the sending method. For Portugal there are two connection methods, and each requires different fields:
    • Option A: SEF-SIBA web service integration
    • Option B: SEF-SIBA Página no portal integration
    Always choose the option that matches the sending method (Método de envio) currently configured in your SIBA account. If the two do not match, validation and data transfer will fail.
  5. Complete the fields for the method you selected. The details for each option are described below.

Option A: SEF-SIBA Web Service Integration

Use the same credentials you use to access the SIBA portal. The required login fields are:

  • Username in Holidu: Unidade Hoteleira (NIF of the hotel unit)
  • Password in Holidu: Chave de Ativação (activation key)
  • Establishment number in Holidu: Estabelecimento (establishment code)

For the remaining fields (postal code, postal area, contact name, email and phone number), enter exactly the same information shown in your SIBA account under "Atualização dos dados de inscrição". 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. Only three fields are required:

  • Username in Holidu: Unidade Hoteleira (NIF)
  • Password in Holidu: Chave de Ativação (activation key)
  • Establishment number in Holidu: Estabelecimento (establishment code)

No address or contact details are needed for this option. Select "Página no portal" only 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, because the change must be requested from SIBA.

  1. Check the current method in the SIBA portal under "Atualização dos dados de inscrição".
  2. If it is not the method you want, collect your NIF (your company or host tax number) and the establishment number of every property that needs to be changed.
  3. Send an email to siba@ssi.gov.pt requesting the change of submission method (for example, to Web Service).
  4. Wait for SIBA's confirmation that the change has been processed.
  5. Once confirmed, return to the configuration form in your Holidu app, select the matching sending method, complete the required fields, and validate again.
  6. Click "Validate". When it shows "Completed!", click "Save Changes".
  7. Once completed, the connection is active.

3. What Happens After the Activation

After activation, future bookings with a check-in date at least 6 days after the configuration is completed will be linked to a check-in form. Holidu sends this form to guests by email or through the booking platform message.
