Hi @ian.kennedy,
Thanks for reaching out to the Auth0 Community!
I understand that you would like to generate a URL that brings your users to your sign-up page instead of the login page.
To do so, you will need to use the New Universal Login Experience and specify the screen_hint=signup
query parameter.
For example:
https://YOUR_DOMAIN/authorize?
response_type=code&
client_id=YOUR_CLIENT_ID&
redirect_uri=https://YOUR_APP/callback&
scope=SCOPE&
state=STATE&
screen_hint=signup
See here to learn more.
Please let me know if you have any questions.
Thank you.
