2 new properties (dynamic_fields)

If you enabled Custom Conversion Columns in your request, the response object will include 2 new properties. Both properties share the same name: dynamic_fields:

1. A dynamic_fields property is present in each row (object) within the results array. This collection stores the actual values for the custom conversion columns.
2. Another dynamic_fields property appears within the metadata section (object) of the response object. This collection defines the metadata (Unique ID, Caption, Data Type, etc) for each custom conversion column.
