This page is part of the Redirect Node Demo! The 'Return to Experiment' button below will only work if you accessed this page via a preview of the demo experiment.
Click the 'Return to Experiment' button below to resume the Redirect Node Demo experiment.
This demo provides one example of how to set up the Redirect Node. The exact way you set it up for your study will depend on the external site you are sending participants to.
In a real experiment, you would usually redirect your participants to Qualtrics or another external survey site. Your participants would then complete your external task. Once they finish, they can click a link to return to your Gorilla experiment. With most recruitment policies, you should be able to append the participant ID when you send the participant from Gorilla to the external site and back to Gorilla. If you can do this, then the participant will be recognised when they return and automatically resume where they left off.
If you are unable to append the participant ID, the alternative is to use the Completion Token method, as in this demo. In the 'Completion' setting on the Redirect Node, Completion Token is selected. This means the participant is sent to the external site with a unique completion token appended to the URL (you should see this in the address bar above). Some JavaScript code on this page then extracts the completion token from the URL and appends it to the 'Return to Experiment' URL. You can see this code by right-clicking on the page and selecting 'View page source'. When the participant clicks 'Return to Experiment', they are sent back to resume the experiment with their completion token appended to the URL. This means Gorilla recognises them and resumes them from where they left off.
You can find more information on how to set up the Redirect Node for your study on the Redirect Node page. If you have any trouble setting up your redirection, don't hesitate to contact the support desk!
