handover url

Is it possible to update the handover urls everytime a different user accesses the package? We have users who will access the document via sa personalised URL and we are hoping that after signing it would navigate them back to their personal url.

The idea that I have is that once the user access his personalised url, a web service gets initialised to update the handover url, so when he proceeds to sign the document, clicking return would navigate him back to his personalised url.

Is this possible? I'm currently getting 405 error when I try to do it.

Thank you!
