Webform one-time submission token+URL

Question

I have two webforms:

1. Email webform: asks for the user's email address.
2. Voting webform: contains an entity selection list from which the user can select one and submit their vote.

In the email webform, there is a confirmation email sent to the submitted email address. In this confirmation email, I want to have an URL that points to the voting webform, and I want this to be a one-time-URL, as I want the users to access the voting webform in this way to validate that the submitted email is live and functioning.

What is the best solution for this?

Answer 1

Webform has numerous capabilities for limiting submissions, and doesn't require arbitrary links: https://www.drupal.org/node/3080869
