Hidden Fields are masked in the responses tab

@pad408 - they are probably not masked, they look to be the default values that were passed by the share link when you create it .. for example

domain.typeform.com/to/jNVGQmtk#v_firstname=xxxxx&v_lastname=xxxxx&v_company=xxxxx&v_email=xxxxx&v_phone=xxxxx&v_reponsibility=xxxxx

 that is an example from a test form that i have created. 

you would need to replace the xxxxx strings with the appropriate values for the variables you are passing into the form. 

you can hard code it .. for example #v_firstname=joihn&…… 

or your crm or esp should be able to dynamically insert the value in the field of the crm/esp database if you use the appropriate syntax in your link … for example: 

… #v_firstname={{subscriber.firstname}}&…
