Switching
DataPenny reads DataFast’s conventions. data-fast-goal attributes, window.datafast() calls, the datafast_visitor_id cookie and checkout metadata keep working, and the Payments API takes the same field names. On most sites you swap the script tag, and sales that carry the old id still match.
