I'm using Luminate Web Services (LWS) to upload constituents using the Create method. I keep receiving a MATCH_EXISTING error, but when I search for the constituents in Cons360 I don't find anything.
The matching logic used for LWS is the same as the matching logic for everything else within Luminate Online. One piece of the matching logic involves looking for constituents based on emails that have been associated with their profile at some other time whether through donations, TeamRaiser registrations, etc. This is done intentionally to decrease the likelihood of duplicates.
