Unique Links: Automatically associate participant data and prevent duplicate submissions
Updated over a week ago

πŸ‘‰ Unique Links are only available to users on the Ask tier or higher.

Unique Links allows you to create survey links that can be configured to (a) only be used once before expiring, and (b) automatically associate data against participant profiles without having to ask for this data in your survey (eg. like a Hidden Fields feature).

This guide explains how the Unique Links feature works and explains how to set up your own list of unique links for your survey.

How to create a list of Unique Links?

Start by opening the Results Overview tab of your survey dashboard and go to the Survey Participants table, which will look like this if your survey has no participants yet:

Clicking the "Import" button will cause a popup to appear where you can upload your list of emails, either by dropping a file into the box or by opening up your file explorer and picking the file you want to import. Once imported, you'll be shown a list of all emails found in your file and asked to confirm which you want to add (they're all marked as "yes" by default).

Once you click that green "Import" button, all emails will be added to your invite list. This will take you back to your survey dashboard, where you'll now see all those email addresses shown under an "Imported Participants" table:

Next, click the "Configure Invites" button in the top-right corner of this table:

On this popup, there are two route you can follow:

  • Export Links will download a .csv list that contains each of the email addresses you imported and their associated unique link. Any user on the Ask tier or higher can export their list of unique links for free.

  • Send Emails will send each of the addresses you imported an email that contains their unique link, helping you distribute these links in one click (note: $0.10 charge per invite sent).

Once you hit the "Export Links" button, you will download a .csv file that looks like this:

It contains a list of the email address, status ("pending" meaning that no invite has been sent yet and the link has not been used at the time of download), and the unique submission link.

Creating Unique Links without email addresses?

Currently the Unique Links feature only works when it has an email address associated with it. If you do not want to use real emails, I recommend just importing a list of dummy emails (it does not matter if they are not real emails, just so long as they follow a real email format).

For example, I like creating dummy emails that contain actual segmentation data, like in the screenshot below:

The benefit of this approach is that you can embed data about each user in the dummy email address, which will then be automatically associated with their participant profile on your survey's results page. I have used this in the past along with the Participant Tab Edits feature to manually add segmentation data to participant profiles after my survey so that I can conduct more detailed analysis without having to ask for this info from participants in my survey.

Configuring my Unique Links

Unique Links can be configured for:

  • Single-Use: After someone has completed the survey one time using the link, the survey cannot be accessed again using the same URL, therefore preventing duplicate submissions. Anyone who tried to use an expired link will reach a dead-end page informing them that the link is no longer valid.

  • Multi-Use: Anyone using the link after the first participant will be able to complete the survey but will be registered as a new user without any of the imported data associated against their participant profile on OpinionX.

Set your survey's unique links to be single-use or multi-use using the checkbox (shown in the screenshot below) that appears when you are configuring the Email Invites. Note: editing the single/multi-use setting affects all unique links associated with your survey (including previously distributed links).
