Getting started: company, property and SES credentials

There is no company to create first any more. The first time you sign in, the dashboard takes you straight to a single screen: "Set up your accommodation". There you give it a name, say where it is, and enter the three SES Hospedajes credentials the traveller reports are filed with. Nothing else.

The property name is never sent to the Ministry; it is the one you will see in your own dashboard. If you also fill in the "Commercial name" — the name of your Airbnb or Booking.com listing — that is the one the guest sees during check-in.

City and province are worth filling in right away: BookCheckin uses them to warn you if your property is in Catalonia or the Basque Country, regions that don't file traveller reports through SES Hospedajes (the FAQ below explains this).

If you manage properties belonging to several companies, you can create companies from Settings whenever you need them. For a single property none of that is necessary, and you will not be asked.

The main button is "Save and check": it saves the property and then, straight away, tests the credentials against the Ministry. There is no separate test button to hunt for on another screen afterwards, and you do not need a subscription to do it.

If you don't have your web-service credentials yet — registering with SES Hospedajes is an external procedure that takes its time — use "Save without credentials for now". The property is saved, and the first item on the dashboard's task list stays open, linking back to that property's Legal tab so you can finish it off once you have them.

The establishment code and the lessor code are the identifiers the Ministry of the Interior assigns to your property inside SES Hospedajes. You receive them when you register as a host on the official portal — BookCheckin doesn't generate them.

They're optional when you create the property — you can save it without them and add them later from the property's own page. But you won't be able to file traveller reports until they're set.

These credentials are for your Ministry of the Interior web service, not your personal Cl@ve login, digital certificate, or electronic ID. You request and manage them from the SES Hospedajes portal itself.

BookCheckin uses them to authenticate and send traveller reports automatically on your behalf, within the legal 24-hour window. Like the codes, they're optional at this step — you can create the property without them and add them later.

They are managed per entity (the arrendador), under “Servicio de comunicación” → “Credenciales” on the SES Hospedajes portal — not inside each establishment's own registration. If you haven't registered yet, see the prerequisite at the top of this guide.

Once you save the property with a username and password filled in, the "Test Connection" button appears. Always click it: besides confirming the Ministry accepts those credentials, it's a requirement — the property can't create check-in links until a test ends in "Connected!".

"Connected!" only confirms that the username and password authenticate with the Ministry — it does not guarantee that any specific submission will be accepted. An individual report can still fail afterward for other reasons (a malformed postal code, an unsupported document type…) that have nothing to do with whether the connection works.

None of this is final at creation time. From the property's page, under the "Legal" tab, you can edit the SES codes and the Ministry credentials whenever you need to, without recreating anything. One thing to remember: changing the username, password, or codes invalidates the previous verification — click "Test Connection" again after saving.

The password is stored hidden; the eye icon next to it reveals it only when you ask (and only if you're an owner or manager), and it isn't shown by default, even to you.
