Adding url parameters to study link
I am trying to embed a study created with lab.js and hosted on our server with JATOS into Qualtrics. I need to send information from the Qualtrics survey to the study and wanted to do this via url parameters. The problem is that something deletes the added parameters from the url, e.g. the url ".../jatos/publix/56/start?batchId=56&generalMultiple¶mA=123¶mB=456" turns into something like ".../jatos/publix/56/72/start?srid=336" when called from Qualtrics (or manually in the browser). The parameters are gone. I also tried other worker types url - same problem. Does anyone have any idea how to fix this?
