Prevent Multiple Submissions and different URL Embedded Variables | XM Community
Skip to main content

I want to distribute a survey to Hotel/Resort guests. I will distribute using a third party software that will append variables into the URL. I want respondents to be able to take the survey once for each stay (or each unique reservation ID), so I will use a variable called ReservationID=XXXXX, and append it into the URL.

Question: If I have prevent multiple submissions turned on, will changing the ReservationID in the link allow respondents to submit a new response?

Supposedly Prevent Multiple Submissions puts a cookie into your browser that prevents users from taking the survey multiple times, but it seems like a slight change to the URL will allow them to take it again.

Another note: I cannot create a contact list and use an authenticator, as there are too many respondents coming in every day to make this feasible. 

Sorry for the multiple posts guys. I’ll update current posts in the future.

We use appended URLs that scrape in embedded date. I just checked in my data & analysis tab and we haven’t had any duplicates (n=3k+). I’m not saying that this though is not a possibility - you could easily export to excel and run a duplicate rule to flag any duplicates.

 

Something else is depending on where your contacts are coming from is you can make a workflow that would auto upload the contacts and auto distribute the survey via personal link - we use this feature with SalesForce to Qualtrics and it runs so smoothly!
