@westerndeal Thanks for the answer! I’ll use the date & time for now to create an ID. As long as I have not two entries in the same second (still unlikely, even though I saw a small difference of 1-2s in between the smart tag time and the time in the sheet) this works fine. But yes, it would be handy to have access to the tags!
Alright, next try: I try to get other smart tags, e.g. {url_referer} or {user_ip} to make an unique ID. While all the fields get fine into the GSheet, the tags don’t. They do work in the notification emails…
