hey man, just wondering if you ever figured out the solution to this!
I was worried about this too and did some searching. I got tired of not finding anything concrete and entered www.codecademy.com and didn’t haven’t had any issues getting venues to render in my code. I think they only require it so they can validate or verify the source of the requests to some extent, however, on a free account I can’t imagine they’re terribly concerned.
For me the same just entering the url of the project itself
i need the answer to this question as well, nothing said here works for me
