I am trying to get a connected app setup to authorize with Salesforce. Our app has a different subdomain for every client so we wouldn't be able to use www.domain.com/callback. What I'd like to be able to do is add wildcards to the callback url so as long as it fit into a certain pattern the callback url would be valid.

I have tried using the above url but it doesn't work. I see this error.
Is this possible with some other syntax?
