Hi @dvbridges, thanks for your reply. In the documentation, I find how to have psychopy read info from URLs and to write **static** information into URLs.

I’m looking for something a bit different: I want to have psychopy write **dynamic** info, such as the participant id into the completionURL.

Specifically, I want to redirect participants to Qualtrics after completing the experiment and have psychopy write the variable participant (unique for each ppt) into the completionURL, to have Qualtrics read it.
