Add parameters and tags to the Participation Link

When running an eye-tracking study in RealEye, you can add parameters and tags to the Participation Link to track additional participant information.

1. Built-in parameters

RealEye offers several built-in parameters that integrate directly with the system:

• realeye-tester-external_id: when redirecting participants, for example, from your external survey to RealEye, this parameter can be used to pass the participant's (External) ID. 

• realeye-tester-age & realeye-tester-gender: if you don't want to (or can't) use the RealEye built-in post-test demographic survey, you can provide age and gender directly through these parameters. They will automatically upload as the participant's demographic data.

To use these parameters, append them to your Participation Link, using ? for the first parameter and & for additional ones. So before a user takes part in your study, the Participation Link that you send to your testers should look as follows:

https://app.realeye.io/test/study_id/run?realeye-tester-external_id=external_id&realeye-tester-age=age&realeye-tester-gender=gender

In RealEye, the values collected through these parameters will appear as:

• External ID in the Participants list in Results
• Age and Gender in participant demographic data, available for filtering
• External Data next to other (built-in or custom) parameters

2. Custom parameters

You can also add custom parameters to track additional participant information alongside the built-in parameters.

Let's say you want to share your study with participants from different groups based on their location and team_name. Therefore, you can append these parameters to your Participation Link, using ? for the first parameter and & for additional one(s).

So before a user takes part in your study, the Participation Link you send to your testers should look as follows:

https://app.realeye.io/test/study_id/run?location=location&team_name=team_name

In RealEye, the values collected through these parameters will appear as External Data next to other (built-in or custom) parameters.

3. Tags

Tags allow you to label and filter participants in a simple way in the Analytics Dashboard (learn more here: Heatmaps: how to read and interpret them). They can be added to the Participation Link as a realeye-tester-tags parameter. Multiple tags should be separated by commas (,).

So before a user takes part in your study, the Participation Link you send to your testers should look as follows:

https://app.realeye.io/test/study_id/run?realeye-tester-tags=tag1,tag2

In RealEye, the values collected through these parameters will appear as Tags.

Tags can also be added manually or imported from a CSV file in the Participants list in Results after the study has started.
