Google Apps Script: access to a form key that allows the user to edit their responses

Question

In the Google Apps for Education domain, we can create forms that allow users to edit their response.

This sends a link to the sender with a URL that they can use to edit their response. This is essentially the URL of the form with a unique key at the end.

At the time of sending, I would like to receive this key and save it with the form data for each user.

We are creating the Alumni website (where all users will be authenticated in our domain), and we would like to update my profile page. This will be empty the first time a user logs in. But then, when they return, I would like the script to search for the username for the submitted entries, and if the user is found, direct them to the link that allows them to update their profile.

During the first submission, Google automatically sends the URL to the user. However, it is unlikely that they will have this email in a few years, so if we could provide a link for them, it would be much easier for the user.

Answer 1

I have a similar problem. One solution is to implement the Gmail plugin (if all users are Gmail users). The plugin can parse the message (extractor) and get the key / or the entire URL. But you need to save in some database in order to gain access later.

If we have a way to list the form keys, this should be much better!
