Help with OTree Integration

Hi everyone,

I am woundering if there is a best practice regarding how to automatically record Prolific IDs when using oTree. The help page has infos regarding different platforms but not oTree.

Thanks a lot in advance :slight_smile:

Hi Jan!

I also use oTree and until know have been recording the IDs with an initial screen asking participants to manually insert them. However, I also want to switch to the automated version and have been wondering the same.

Although Prolific does not mention oTree in the software integration guide, oTree does mention Prolific (scroll down to the end of this page). I haven’t tried this way yet, but if I do I’ll make sure to share my experience with you.

Hi everyone,

quick update: Yes, the official oTree-documentation mentions an intergration via oTree HR.
I had a first look at it. So far, this seems to be the way to go (it should take care of Prolific IDs, completion links and automated payments).

It seems that oTree 5 is required.

Best,

Just bumping the post to ask whether you managed to solve the issue with automatic collection of Prolific IDs and if yes, if with oTree HR or without it.

Any insight would be appreciated, I think also from the rest of the Community which uses oTree!

Thank you :slight_smile:

Hi Veronica,

yes, I used oTreeHR and everything went well :-).

A few changes need to be done in the oTree-code. I think they are fairly straight forward and they are explained on oTreeHR. (For this point, I had help from a programer, it was faster this way).

  • You need to copy the oTree-Session-code into oTreeHR.
  • After this, you need to copy the study Link form oTreeHR to Prolific. And to copy the study-completion-link from Prolific to oTreeHR.

I hope that helps. I hope I am not forgetting anything.

Best,
Jan
