This will grab a json dump with a bunch of posts in. If you copy-paste that output into a json parser, you can find all the link_flair_template_id values in there (or at least, the ones most used in posts).
It’s not the most efficient way, but it’s the best one I’ve found.
Ofc you can get Make to loop over this and find those template_id’s for you.
I meant to update this, but you are correct, a friend helped and it is infact an ID value that goes here, maybe the module should be updated to say this in brackets so people don’t enter text, but it’s only a minor issue
Yes finding the ID is a pain, my friend had another method too which took a little longer, I will attempt this now just so I understand it, but thanks for the solution and help, I do appreciate it
