Use this endpoint to allow a new user to register an account in your project. Use the success and failure URLs to redirect users back to your application after signup completes.
If registration completes successfully user will be sent with a confirmation email in order to confirm he is the owner of the account email address. Use the confirmation parameter to redirect the user from the confirmation email back to your app. When the user is redirected, use the /auth/confirm endpoint to complete the account confirmation.
Please notice that in order to avoid a Redirect Attack the only valid redirect URLs are the ones from domains you have set when adding your platforms in the console interface.
