Yeah, this is more or less what I suggested. Well, if you are not a developer and you don't want to add the tokens by hand, then I think what you want to do will be difficult.
If the survey doesn't need to be sent immediately after the ticket was closed, you could create a csv file of all tickets and upload them once a day or something. this would still be by hand, but at least not for each single thing.
