Hi,

When otree HR generates a study link for Prolific, there are 3 URL parameters that get populated: PROLIFIC_PID, STUDY_ID, SESSION_ID. Otree HR grabs PROLIFIC_PID from the url and records it under participant.label. Is there a way to capture STUDY_ID, and record it under session.label (or something else).

Thanks,
Kim

Check participant.vars, I believe it’s stored in there.

Hi both, I have been trying to store these values, but they are surely not stored in participant.vars -- at least not automatically. Have you been successful in retrieving these vaue from the URL?
