I am trying to make Qualtrics work via Tealium.I managed to make it work both via Tag and Extension separately.But via Tag I had to create a base_url UDO variable and replace it with the url in the template by mapping the variable, instead of the tag just being configurable (by adding survey id and site intercept server. Is there any better way to handle this? Or do I just make changes to the base_url in the template? Is there a way by which I can create a lookup table or something in Tealium which will load a particular Qualtrics survey based on the url and survey combination. The objective is that I want to create sort of like 1 Qualtrics code and a configuration which is scalable. Which one should I use, if I want to scale, tag or extension? Anyone who has done this via Tealium, any best practices or recommendations?
