I’m conducting a survey, which needs to be answered by a closed set of people (all of them), after receiving the link to the form via e-mail. The issue is that I need to be able to identify the people that have already answered, without relying solely on responses on the form that may have typos or erroneous information, so I’m wondering if there’s anyway in which I can capture any information to make it possible.
I’m thinking of something like the e-mail address capture that can be done on Google Forms. It
could also be a pre-assigned ID number. Since I’m emailing the link to the people that need to respond, and I can previously tailor them for each one of the respondents, I’m wondering if it is possible to extract and store information on the link (just like the form can redirect to an external page upon submission, fill a field on the form according to the link), or maybe even an exernal service that allows me to see if the particular link has been opened.
I’m really lost here, so I’m sorry if the question is a bit messy, but I’d really appreciate any solution.
Thanks in advance.
