Extended Network Data

In an effort to provide more data for use in analyzing your transactions and customers, Worldpay added a number of data elements originating directly from the ISO 8583 network response messages. If you use V11.0 or above of the Worldpay cnpAPI, you can receive up to 17 data elements as part of the Enhanced Auth Response (<enhancedAuthResponse> element). These elements provide more granular data, allowing you to gain a more nuanced understanding of the approval/decline behavior of particular Issuers. Table 1-7 provides information about the fields returned.

To receive the Extended Network Data elements you must code to Version V11.0 or above.
