For verified customers, what special characters will be accepted\rejected for the different fields? When I try testing on the sandbox, a hyphen is allowed (as it should be). I was looking through the API docs and the particular characters which are accepted are only listed for the addendum field on a different object. I just want to make sure I perform validation on the front-end in accordance with acceptable criteria on your side.
lastName yes string An individual Customer’s last name. Must be less than or equal to 50 characters and contain no special characters.
