OTOBO version: 10.1
OTOBO installation type: apache 2

I’m using postman to call OTOBO webservices and it responds:
{
„Error“: {
„ErrorCode“: „TicketCreate.AuthFail“,
„ErrorMessage“: „TicketCreate: User could not be authenticated!“
}
}

Request :

url : https://tickets.consejocaba.org.ar/otobo/nph-genericinterface.pl/Webservice/ws1/TicketCreate

{
„UserLogin“: „ignecco“,
„Password“: „xxxxx“,
„Ticket“: {
„Title“: „created by Webservice request“,
„QueueID“: 5,
„CustomerUser“: „CustomerUser“,
„State“: „new“,
„PriorityID“: 1
},
„Article“: {
„CommunicationChannel“: „Email“,
„From“: „test@test.de“,
„Subject“: „Webservice Create Example“,
„Body“: „This was created by a Webservice request!“,
„ContentType“: „text/html charset=utf-8“
}
}

Is this user to be used a special service user or what user is it?
I used my user with which I access the OTOBO system for front-end use, and that one doesn’t work for me for postman
