I’m trying to accomplish the same thing as the OP and need some clarification.
I’m an engineer for a SaaS platform where each of my clients also has their own subdomain, e.g.: clienta.mysaas.com
Because of that, a single redirect uri doesn’t work because they authenticate within my app based on the subdomain.
What I need to do is allow the user to go to clienta.mysaas.com, login to my application and then click a button to install Zoom. So what I need to do from there is pass their subdomain clienta as a state query parameter so that the redirect_uri that I setup in my OAuth app now has a context of the client so it knows how to store access/refresh tokens for that particular client.
Does Visit site to Install accomplish that? Is it possible to do that?
