Hi,

Please can someone help me 😉 I came across this video https://youtu.be/-AtYOBnQjyw [at 3:27'']and would like to know how this can be done in esign as is so useful.

he has a form on a webpage and once he has completed the info and hit submit, the info will then be dynamically filled into adobe sign. I have also attached screenshots. Much appreciated if someone can shed some light how this can be done!

thanks
