Is box API suitable to sign pdf and then return to original website?

We were wanting to create a website where:

1. a person enters their details

2. a PDF is created with the entered details

3. the user is redirected to a URL to sign the PDF

4.  once signed, return user to the original website.

Is box suitable to do this?  If so is there any demos code to do this? It is quite easy to do with docusign API. Looking through the box examples most seem to be more about file storage and not with esignatures.
