Testing links between Prolific, Qualtrics and Pavlovia

I’m trying to link Prolific (recruitment) to Qualtrics (consent) and then Pavlovia (testing). I’d like to test whether this all works. I can get Qualtrics to redirect to my Pavlovia study but I’d like to test whether this works when participants come from Prolific.

Prolific allows you to ‘Preview’ your study. When I do this, it takes me to my Qualtrics survey, but at the point where it should then link to the Pavlovia study I get an error message: ‘The pilot token is invalid’.

The experiment is set to ‘Running’ on Pavlovia and works from there, and also from the Qualtrics redirect link.
