The credentials of the communication service:
What are they and how to get them
For your traveler parts to send themselves to the Ministry of the Interior, you need three data that the Ministry itself gives you free when registering in SES.Hospedajes. Here we tell you what they are, what they are for and where to find them, with the same steps that you will see on their website.
What is the communication service?
It is the "automatic window" of SES. Accommodations: A web service of the Ministry of the Interior that allows sending communications of travelers automatically, without entering every day to fill out forms. Our platform uses it on your behalf —that's why you need your credentials— and also allows you to consult what has been sent and canceled communications if necessary.
Each entry, one form.
You enter the Ministry's website, you put a username and password, type in the data of each guest one by one and give them to send. Every day, with each check-in, within the legal term.
If you miss a day, the part does not show up.
Your parts travel alone.
You save your credentials only once in your hosting panel and, from there, each part of travelers is automatically sent to the Ministry, with acknowledgment and registration of each shipment.
You just look at the traffic light: green, all presented.
The three facts you need
All are issued by the Ministry when registering in SES. Accommodations. Without any of the three, automatic shipping cannot work: they are the key that identifies who is sending and why.
1 Lesser code
Identify your entity (you or your company) in the ministry system. You will also see it called "Registered Entity Code".
Ex: 0000012345
2 · Web service username and password
some credentials specific for automatic shipping. The user is your NIF/NIE ending in WS And the password is different from the one you use to enter the Ministry's website.
Ex: X0000000TWS
3 · Establishment codes
A code for each accommodation you register. Indicates which establishment each part of travelers that is sent belongs to.
one for accommodation
✅ The box that changes everything
The Ministry only generates the credentials of the web service if you check the box Sending communications by web service in your SES.Hospedajes record. Without that checked box, they don't exist: no matter how much you search, you won't find any finished user in WS.
When you mark it, it will also ask you for a Notifications email: There the ministry will notify you if any communication sent contains errors. Put an email you really check.
This box is correct whether you connect your own program or use an intermediary that you send in your name —which is exactly what makes you host to you—. You can only leave it unchecked if you plan to type all the parts by hand on the ministry's website.
How to get them, depending on your case
There are two possible situations. Both end up the same: with your web service credentials ready to paste into your hosting panel.

Frequently asked questions
The doubts that come to us the most about the credentials of the communication service.
How is the web service user different from my normal user?
They are two different things. With your normal user (your ID/NIE) you enter you On the SES.hospedajes website. The user of the web service —the one that ends in WS— It is the one used by the programs, such as hostages, to send communications on your behalf.
Each has its own password. For automatic sending we need the one ending in WS.
Do web service passwords expire?
No, they don't expire. Even so, the Ministry itself recommends changing them from time to time for security. If you change it, remember to update it also in your hosting settings, or shipments will start to fail.
I can't find the "communication service" option in SES. Accommodations
That option only appears if you have the “Web Service Submissions” box checked. If you don't see it, go to "My registered data", check the box, add the notification email and save: the option will appear on the home page.
I forgot the password of the web service, what do I do?
Go to SES.Hospedajes, go to “Communication Service”, select your entity and use the Modify Password button that appears on the form. Then, update the new password in your Seshospedajes settings.
If the ministry has blocked the user for several failed attempts, you will have to reset the password right there before continuing to send.
Do I have to check the box if I communicate the parts by hand?
If you are really going to type all the communications in the Ministry form (or upload them by massive file registration), it is not necessary to mark it.
But if you want to send them automatically —which is the grace of all this—, the box is mandatory: without it there are no credentials that the platform needs.
Where do I find my establishment codes?
They arrive in the registration confirmation email and you can consult them whenever you want at SES. Hospedajes, in the option «My registered data». Each accommodation you register has its own code.
What's that batch code and communication code?
They are numbers that the ministry returns with each submission, not credentials. The Batch code Identifies each sending request (a group of communications); When the Ministry processes and accepts each communication, it also assigns a communication code only, which is the one used to cancel it if necessary.
The good news: You don't have to write them down. Seshospedajes automatically saves them with each shipment.
