I am sorry for my Engloish
Offically you wont get support here for a 3rd party Channel manager, only the initial authorisation info for this side of the connection.
Having said that if any other partner is using it and sees this they may or may not choose to reply.
Note; I myself have never seen mention of this particular Channel Manager.
See Extranet > top right circle menu , first menu, channel manager for more details
I found travelline support contact info here ;
