Category based QR codes and interview links
Create interview links and QR codes for a group of participants based on a category, for example, all employees based in a location.
This feature is available on request. Please contact our Helpdesk team to talk about your requirements.
Include the category question
Add the category question to the questionnaire as a Single Choice question. This provides the information to group the participants and send the relevant interview links or display the QR codes.
Define the category
When the questionnaire is complete, publish the survey.
- Click the Collect tab, which opens in the Overview section.
- Click the Publish current version button to publish your survey.

After publishing for the first time, the Web Interviews section becomes available. You can set the category used to categorise the interview links and QR codes.
- Click the Define categories button.

- In Categorise URLs using variables, select the survey variable you want to group participants.
- By default, all codes are used. If you want to use a subset of the codes, enter the mask expression in the CodeMask box. You should enter the code mask as a comma-separated list of numbers, for example, enter 1,2,5 to include the codes with values 1, 2 and 5 only.
- Click Save to use the selected category.

This shows each code available in the category along with the Interview URL, QR code and Preview link for participants with that code selected.
