Am I missing something or is there a function to strictly update a user's information (email, username, custom fields) instead of adding it?
My gameplan now is to check to see if the user is subscribed and then if they are update their information but I was wondering if anyone had a better idea that may not require two hits to Campaign Monitor.
I'm using the PHP class made by Kaiser Shahid and that seems to be the only way.
Can someone else provide some insight?
Calling the Add functions with an email address that already exists will update the information for that subscriber. And if they don't exist, the add will add them of course.
