I am using auth0 in my existing regular php web application.
I have free as well as paid users in my site. For free users registration process is simple, I call the create user api which triggers the verification email.
But for paid users I have a multistep form. In first step users enters his information and registered as a free user in application then redirected to payment page. I can not call auth0 reg api after first step as user will get immediately verification email before payment.
If I call it after successful payment then its impossible to track if user bails out(Doesn’t fill payment form, but already registered as a free user). Please suggest what approach I should follow.
