Add Parameter to Callback URL

Hi All,

Is it possible to add a parameter to a callback URL? What I’m looking to add is:


where [email] is the email address of the person logging in via Auth0.

All pointers gratefully received!

Can you give a little more info here? What flow are you using and what are you trying to achieve?


Hi John,

We have a regular web application (a MS Dynamics 365 Portal) and are using Auth0 to authenticate access for customers (Username-password-authentication). We’re looking to add a parameter (or modify an existing one) to add _clde=[email] into the return URL where [email] is the email (username) of the person signing in.

Hey there!

Wanted to reach out to know if you still require further assistance?
