Creating and setting value for custom profile fields
We would like to create custom profile fields, and then set values for them. We were told this was possible by our Lithium contact, but I'm having difficulty finding documentation on how to do this. Also, there are many posts such as this one which say that professional services are required to do this. We are fine using the API, would just love to see where this is documented.
The question at hand is this: we want to display a popup to each user 1 time only. After the user dismisses the popup, we want to never show the popup again. We'd like to use a custom profile field (not visible to the user) to store this value (instead of using browser cookies), so the user will be recognized as having dismissed the popup no matter which device they're on or if they clear their browser cookies.
