Hi Awijit
Thanks for your advice.
My Page has a menu page where links of various function pages are collected as the top page. Usually, when you access My Page, you will go to this top page after login. This is normal behavior.
As a page to transition from the menu page, there are change of customer information (registered address, registered telephone number), contract detail page, inquiry screen, and so on.
What I want to do this time is to send a confirmation email of registration information to my page users, but when accessed from the URL described in the email, transition to the customer information page directly after login.
Current my page, it is redirect to the top page after login.
