Use Matching Rules for Shopper Account Identification

Order Management identifies an existing shopper by matching the shopper’s name or email address to an existing Account, Contact, or Person Account record. However, you can configure Order Management to use your org’s duplicate and matching rules instead when looking for existing shoppers.

1. From Setup, in the Quick Find box, find and select Order Management.
2. Switch the B2C Integration Data Matching Rules option to Active.
   If your matching rules identify multiple potential duplicate records, Order Management selects the one with the highest match score. If multiple records tie for the highest match score, you can’t guarantee which is selected.
