How to take specific action when authorization is denied in a Pre User Registration Auth0 custom Action

Hi @stephenrs,

Welcome to the Auth0 Community!

@stephenrs

I would like to take different actions on our end, such as redirecting to specific pages, depending on the “reason” a user has been denied access. However, I haven’t found a way to access the “reason” after the access denial occurs.

Yes, this happens because the api.access.deny() method stops the sign up process immediately and prevents any further actions from being executed. (Reference: Actions Triggers: pre-user-registration - API Object)

It’s also important to note that a pre-user registration action will not allow you to redirect users to external pages. Only a post-login action can redirect users.

If you need to redirect your users based on certain conditions after they sign up, you should use a post-login action instead.

So, how can I find out the “reason” a user has been denied access from a Pre User Registration custom Action?

You can find out the reason a user has been denied access by checking your logs.

Let me know if you have any questions.

Thanks,
Rueben
