Hi there Sosci-Pros!
We are currently working on our first two-part study and are struggling with a few things. Here are some questions we need your help with:
We want participants to receive an e-mail with an invitation link to the second part of the study after they have completed the first part of the study. We need to be able to match the results for each person from the first part to the next part though. We are looking for the easiest way to do this and how to implement it, since we are having a hard time working with it:
Does that with serial links best or de wo need to use this function: https://www.soscisurvey.de/help/doku.php/en:survey:mailing-api
Note: we don't want to use another programs
Another possibility are authorization codes, we have tried implementing this but we just couldn't get it working. We thought we could participants have create personalized codes in the first part of the study and use it to access the second part of the question. Is this easier?
Thanks a lot for your help!
