QuickBooks Integration: Retrieving Custom Field Values in qbxml

QuickBooks allows us to create custom fields. Sometimes we are required to retrieve the custom fields in the integration process.

So how do we want to get the custom field values out of an object using qbXML?
We will need to set the OwnerID to 0 in the request.

For example, we perform an ItemServiceQuery request with the following request:

  80000031-1314102902
  0

In return, we will receive the following response including the custom fields and their values:

   
      80000031-1314102902
      ...
      ...
      ...
      ...
