Pulling data from query parameters at end of URL

We need to be able to do this as well, David if you've figured it out, or anyone else knows...

:update, my department's programmers say it isn't possible in psytoolkit. They have to use a workaround where we use qualtrics...

Thank you so much for pointing us too the solution!

As for why qualtrics: Our institution needs to track who did and didn't participate in the study using an identifier assigned by the research participation management software and passed in the link. For the admin purpose of assigning credit for participating, we have to have that list of identifiers to provide back to administrators of the subject pool. The tech people associated with administering the pool have experience with qualtrics, so the solution of passing the original link out of the subject management software to qualtrics to collect that identifier, then having qualtrics pass on the link to psytoolkit, seemed the expedient thing to them.

I'm relieved that the sensible solution already existed, but we'd just overlooked it

Thanks again.

It says "PsyToolkit will also save these variables in its own spreadsheet," but I have not been able to find where the variable (namely, the SURVEY_CODE) is being saved. I am using IN/OUT as directed, though I am also going through Qualtrics. Am I missing something?

Edit: I was indeed missing something. I had pasted whole links in IN and OUT rather than the variable names themselves. For reference, all I needed to put there was: group id

I'm sorry, I just can't find "If you want to get information from calling link" anywhere in the in/out vars documentation...
