Pavlovia - save subject id when running study on Cloud Research Connect

Online experiments
1

I’m hosting a psychopy experiment on pavlovia. Subjects were recruited from Cloud Research Connect. I was wondering if there is anyway to log the subject id on Cloud Research Connect when saving the data (using psychopy data logging functionality via the code component, for example). Is that possible? How do other data collection platforms do this (e.g. prolific)?

Thanks ahead!

Normally you add ?participant=xxx to the URL where xxx is the platform’s code for the subject ID

Thanks! I do have subj id in the URL, but is it possible to get the information from URL to psychopy and then save it?

cloud research connect does append the following to the pavlovia URL automatically:
?participantId=XXXXX&assignmentId=XXXXX&projectId=XXXXX
Is it possible to directly read these info to psychopy?
