OTRS generic interface rest authentication

Question

I'm trying to consume the OTRS generic interface. The rest service is created by the import functionallity. I found the files needed for import here Consuming OTRS TicketConnector from .NET apps

My problem is when I try to consume the interface for example with a curl command

curl http://<user>:<password>@<server-ip>:<port>/otrs/nph-genericinterface.pl/Webservice/GenericTicketConnectorREST/Ticket/<Ticket-id> -X GET

The result of the command is

{"Error":{"ErrorCode":"TicketGet.AuthFail","ErrorMessage":"TicketGet: Authorization failing!"}}

I tried every user/password combination that makes sense to me. I tried the otrs admin account, agent account, customer account, root account of the server, EVERYTHING! I can't find a information in the docs that states wich account type is needed.

Here are some information that are printed out by the webservice debugger

Communication sequence started

$VAR1 = {

Outgoing data before mapping

$VAR1 = {

Long story short: what type of authentication or user type otrs expects to access the generic interface?

Answer 1

In found my mistake. The way I passed the login credentials to the service was wrong.

In my case the user is a agent user.

Here is a working curl command for my service:

curl http://<server-ip>:<port>/otrs/nph-genericinterface.pl/Webservice/GenericTicketConnectorREST/Ticket/<ticket-id>?UserLogin=<username>\&Password=<password> -X GET
