External Study Credit Granting with Gorilla

While these instructions refer to "credit granting", they work for both credit and paid studies. For paid studies, participation will be marked (instead of credit granted) just like with any other paid study.

Here are the basic steps, which are subject to change (since the product is controlled by Gorilla):

  1. On your Sona Systems site, change the Study URL so it includes ?external_id=%SURVEY_CODE% in the URL.
  2. Login on Then click on the experiment that you want to link to Sona. Click on Recruitment (see below) and then Change Recruitment Policy.

  3. Click on the Recruitment Service tab on the Change Recruitment Policy page (see below). Select Sona, then, press OK.

  4. The URL to be used should be generated on the page. Place this in the Study URL field in your Sona study.

  5. For the return URL, you need to put it in the Finish node of the tree. To do this, first click Edit, and then click the Finish node, and then enter the Gorilla.SC Onward URL from the Study Information page on the Sona site into the Onward URL field.

  6. Save those changes, and then click the green Commit button to upload those changes. Now you should be able to start the experiment from Sona, do the trials, and then be redirected back.
