It is not currently possible to get all the values that are entered by a user when customizing an eDocBuilder template. It is possible to send the value of one field back to the Pressero order by using the Identifying Field setting on the Template Info window. Please see the section Identifying Field
on chapter Ch. 020 Template Info Page
for more information.
The eDocBuilder API can update input values into a session, but does not have the ability to get all the input values that were entered into the session.
