Need to "Pass query string to URL"

Hey Webflowers!

I’m trying to enable Single Sign-on (SSO) between Outseta and Tribe. I’ve followed all the documentation that I could find and think I’m pretty close. However, there is one part of the documentation that I cannot figure out (I’m not much of a developer). It says:

To make sure the user is logged in you can pass ?auth=true query string in the URL

I’m not sure how to do this…any help would be greatly appreciated (especially since the client wants to launch tomorrow!)
