Automate SES.Hospedajes with a workflow
A workflow runs your methods as one process, with nobody at the screen. A schedule or a call from your own system starts it, the steps run in order, and the result arrives in your inbox or in the systems you already use.
Today's arrivals without a parte de viajeros
Build this- Starts
- When your system calls the workflow's webhook with the day's arrivals
- Step 1
- For each arrival, check on SES.Hospedajes that a parte de viajeros was sent for that booking.
- Step 2
- Keep the arrivals with no parte de viajeros, or with an error message.
- Step 3
- Email you the list with establecimiento, booking reference, guest surname and check-in date.
Weekly comunicaciones count per establecimiento
Build this- Starts
- Every Monday at 8:00, Europe/Madrid
- Step 1
- For each establecimiento, get the comunicaciones sent in the last 7 days.
- Step 2
- Count partes de viajeros and reservas, and list the ones with an error message.
- Step 3
- Email you one line per establecimiento, with the errors underneath.
New error messages, posted to your property system
Build this- Starts
- Every day at 12:00, Europe/Madrid
- Step 1
- For each establecimiento, get yesterday's and today's comunicaciones.
- Step 2
- Keep the ones with an error message that were not there on the last run.
- Step 3
- Post each one, with booking reference, type and error message, to your webhook.
You can run a workflow by hand on every plan, Free included. Schedules and webhook triggers come with the paid plans, from $29 a month.
Once built, one call from your code
Once you have built a method, it is one POST to /v1/runs from your backend, or a tool an AI agent calls over MCP. This is what “Get sent comunicaciones” would look like.

SES.Hospedajes’s own options
The Ministerio del Interior offers SES.Hospedajes as a web application where you register your entity and establecimientos, then consult and send comunicaciones by hand. For software, a servicio web for sending comunicaciones can be switched on in the registration form, with its own user and password.
| Option | What it covers | What it takes |
|---|---|---|
| Servicio web | Sends partes de viajeros and reservas from your own software or property system. | The box Envío de comunicaciones por servicio web ticked when you register, and the separate WebService user and password you are sent. |
| Registration of entity and establecimientos | Gives you a código de arrendador (host code) and a código de establecimiento for each property. | A digital certificate or Cl@ve, and a signature with Cl@ve Firma or Autofirma. |
| SES.Hospedajes by hand | Consulting and sending comunicaciones one at a time, through Nueva comunicación. | Access through Cl@ve, or with a user name and password without a certificate. |

Signing in to SES.Hospedajes
SES.Hospedajes lets you consult and send comunicaciones either through Cl@ve or with a user name and password, without a certificate. Registering your entity needs a digital certificate or Cl@ve. With Fous you sign in once through the site's own user name and password sign-in with your own account: the login is sealed with AES-256, and an expired session is signed back in.
Worth knowing
- Tick the servicio web box when you register
- The registration form has a box, Envío de comunicaciones por servicio web. Guides for hosts report that if it is left unticked, the registration has to be done again before any software can send for you.
- 24 hours from booking, cancellation or arrival
- Real Decreto 933/2021 asks for the data immediately, and within 24 hours at most, after a booking or contract is made or cancelled, and when the stay begins.
- Two passwords, and one of them expires
- The servicio web password is not the one you use in the web application. The web application password has to be changed from time to time to keep access.
- The número de soporte is easy to miss
- Real Decreto 933/2021 asks for the número de soporte (support number) of the identity document. Hosts report that a parte without it is still accepted with no warning, so check it at check-in.
