If it's there, the profile is duplicate and Authorize.net will have returned the existing profile ID. If that isn't enough and you only want one profile per email, you'll have to store the email address and profile ID in your own database so you can check it prior to creating the profile.</P> Tue, 13 Mar 2012 17:35:00 GMT https://community.developer.cybersource.com/t5/Integration-and-Testing/CIM-what-s-the-best-way-to-check-for-an-existing-customer/m-p/24389#M13077 TJPride 2012-03-13T17:35:00Z
