In some cases, your fillable PDF document will contain fields that you want to always fill with a default value. In order to do so, open the PDF mapper, navigate to the PDF page that contains the field you wish to map and click on it.
In the Field Details panel, type in the default value you wish to use or insert a “macro” from the dropdown.
Note: The default value can be used together with the “connection” dropdown. A field that contains both, will use the default value if the connected template element is left blank by the client/prospect.
