Hey,
What if our user decides to update and change his email? I couldn't find any REST API to perform 'update SignerId'. What is the recipe for such case?
Simply storing the signerId in our database might not be sufficient cause what if user had an email, decided to delete this email, he updates the email in our database to the new one, and some time after the email provider gives back the old email address to the available pool, and someone completely different registers in our portal with his new email (which is the old email of some old user).
