According to this page, I should be able to embed a Slido participant view into an iframe and supply the query parameter user_name=First%20Last to preload the user’s name as “First Last” into the profile. Furthermore, I should also be able to supply user_email and user_company in a similar way.
This doesn’t appear to be working. No matter what values I specify for user_name, user_email, and user_company, the participant view starts with an empty profile. If I was previously logged in, it starts with the logged in profile. In no case that I find does it respect these three query parameters.
It does, at least, appear to respect the lang=fr_CA query parameter, so I can make it French (or whatever language I choose, presumably). So the URL parser isn’t completely broken. But is there something I am missing about the profile parameters?
