The first step in setting up the ITB is understand in the different variables which are needed. There are two types of variables – required and optional.
projectId A string which uniquely identifies the project which the ITB will access.
respondentId A string which uniquely identifies the ITB session.
Only one of these variables – projectId or respondentId is allowed at a time..
redirectUrl A string which represents a Url which will be called when the ITB instance is complete.
displayMessage A string which will be displayed to the user when the ITB instance is complete. E.g. ‘Thank you for your responses. This completes this exercise.’
Only one of these variables – jsFunction, redirectUrl, or displayMessage is allowed at a time.
