Quick question about LoginEx2 or LoginEx API method. The documentation says the following, but I am interested in the last option.
Authenticates a registered user. Accepts a promotion code. Allows three options for authenticating: Username and password, email and password, customer number and phone number and zip code with optional email address for further validation.
I am trying to understand why when I use the customer number, phone number and zip code with optional email to login. Why is it making me log into TNEW again to checkout if I have already been authenticated?
Thanks,
Travis
