We’re using Universal Login hosted page for both sign-up and login, and would like to distinguish in the callback url whether the user performed a login or sign-up event. Currently we pass different values for
redirect_uri when calling
loginWithRedirect depending on what button the user clicks, but they can switch between sign-up and login on the hosted page so this can’t be trusted.
It appears I cannot change the callback URL, by providing a different
auth0.WebAuth on the hosted page, which makes sense from a protocol point of view. So can I alter it at all to add additional URL parameters that I can consume in the callback destination?
Solution could be either using
WebAuth or in a rule, however rules only appear to support the
context.redirect which is not what I want (although could be used, but starting to stretch the design a bit).
