Where do you find domain code and termbase ID

Hi, we are Memsource, a CAT tool provider. We integrate SDL Language Cloud as one of the MT providers. Some of our users have contacted with a request for help - it is possible to specify a domain and enter a link to terminology to improve the MT - see http://take.ms/flbfW. However, our users say they do not see any domain code or termbase ID, they just see names. Could you please help us understand where the code and IDs can be found? Thank you! Vaclav Balacek
