By default, Breadwinner will only link payment transactions that have an existing customer associated with the transaction. There are times when a customer will not be associated with the payment transaction (Example: checkout URL, shopping cart, website). This allows you to link these payment transactions to an existing Breadwinner customer by selecting a common field between the payment transaction and Breadwinner customer record (Example: email address).
