Overview

If the customer database has multiple records with the same email address, we recommend that the alt_customer_id should be used to identify customers instead of the email address. The table below shows the three customers in the Connect database who have the same email address, [email protected]. A new column is added for alt_customer_id.

Customer_id	Alt_customer_id	Active_email_address	Subscription status to “conv”
1002	10001	[email protected]	Subscribed(5)
1005	10012	[email protected]	Subscribed(5)
1007	10023	[email protected]	Subscribed(5)

XML

The XML below shows how to use the alt_customer_id field to unambiguously target the right customer.

<?xml version="1.0" encoding="UTF-8"?>

<kanaRoot>

<EventRequest CompanyName="default" CampaignName="ETCamp5">

<Customer KeyField="Alt_customer_id" Alt_customer_id="10012"

EmailAddress="[email protected]" First_Name="John"

Postal_Code="101201">

</Customer>

</EventRequest>

</kanaRoot>

Result

The customer 1005 receives the email.
Note: The KeyField attribute can have two possible values as follows:

EmailAddress (default): The EmailAddress attribute value is used to fetch the customer from the Connect database.
Alt_customer_id: This attribute is case sensitive. If the attribute is alt_customer_ID then the keyfield entry should be keyfield="alt_customer_ID".
