I'm new to ACS landing pages (very familiar with ACC WebApps).
Can someone please explain to me the following:
What are the enumerated list of options for the reconciliation key? where do they come from? How do each option differ?
If I link from an email, I assume the user is identified through the use of encrypted profile key - so therefore how is the key option relevant?
In the event that unidentified users access the form, how do they reconcile against existing profiles? and are the "form parameter mapping" settings related to this?
2) Adding additional URL parameters
Is it possible to add additional URL parameters to the landing page's URL - and then use the variable value to:
* personalise or dynamically change the page content
* capture the value and store it in the submission data
