HI,

I have a PDF form, which has fields and checkboxes. I created a custom Save button that calls your REST api to merge the annotations. The pdf that I get from your server does have the fields filled out, but the checkboxes are not checked.  
Is this a bug or do I need to run a command prior to calling your API?

Thank you
