Instead of a link to the survey, you can download a QR code that will allow respondents to access your survey even faster.
How to download a QR code?
Go to the survey project you want to share. Open the Results tab and then go to the Survey link tab. Click QR Code in the lower right corner.
The QR code will be downloaded to your computer. The file will be generated in PNG format.
QR code generation when the external_key parameter is added
If you use the external_key parameter in your study, then you can generate a QR code with the parameter added to the link.
After adding the external_key parameter, download the new QR code.
