Payment Data Transfer

100 May, 2005 Merchant User Manual and Integration Guide

3. Click the Website Payment Preferences link, as shown in the following diagram.

The Website Payment Preferences page opens.

4. Click the Payment Data Transfer On radio button, as shown in the following diagram.

NOTE: You must enable Auto Return in order to use Payment Data Transfer. Auto Return can

also be enabled from the Website Payment Preferences page.

5. Click Save.

Getting and Using the Identity Token

When you click Save and save your PDT preferences, a message will appear at the top of the

page indicating that you have successfully saved your preferences. Your identity token will

also appear in the context of this message. You will need to pass this identity token, along with

the transaction token, to PayPal in order to receive information that confirms that the payment

is complete.

For security reasons, the identity token will not be sent to you; however, once you have

enabled PDT, it will permanently appear below the Payment Data Transfer On/Off radio

buttons on the Website Payments Preferences page.
