# Sending Guest Data to SEF (required in Portugal)

Sending Guest Data to SEF (required in Portugal)

### Sending Guest Data to SEF (required in Portugal)

In this article we explain how to connect connect SEF to Chekin in order to send your guest stated data to the authorities.

 Updated over 5 months ago

**Overview:**

If you manage a vacation rental in the Portugal, in order to comply with the local regulations, is mandatory to send guest data to the SEF.

We’re happy to inform you that we’ve just launched the **SEF-SIBA web service integration (beta)** in the **Legal** section of the Chekin dashboard.

This new integration allows properties in Portugal to send guest data to SEF using the **Web Service** method instead of the older “página no portal” method. The feature is currently in **beta** while we run final validations, and the “beta” label will be removed in the coming days once everything is confirmed to be working smoothly.

For the time being, **both integrations will remain available in production** – the new Web Service method and the existing "SEF-SIBA" method (which supports the old “página no portal” flow). We expect to keep both options active for **2–3 months**, to give existing customers time to migrate.

How can clients migrate from the old “SEF-SIBA” integration to the new one?

- Log in to their SEF account at [https://siba.ssi.gov.pt/s/an/default.aspx](https://siba.ssi.gov.pt/s/an/default.aspx)
- Change the **submission method** to **Web Service**
- In the **Legal** section of the Chekin dashboard, update the field **“Automatically send info to”** to **“SEF-SIBA web service integration”**

If you have any questions or feedback during the beta phase, feel free to reach out.

Below is a simple guide on how to do activate SEF in Chekin.
