I've got the following scenario:

1. A respondent starts a Checkbox survey
2. When they get to a certain point, Checkbox will transfer them to a different application passing Survey and Respondent IDs
3. At the end of the middle app, I want to pass back to the Checkbox survey and have the respondent continue with a survey

Is the @@RespondentGuid pipe variable the unique ID for each person taking the survey?

So far, I think I understand how to handle steps 1 and 2. However, is it possible to transfer a respondent back to a Checkbox survey from a different app and have them continue where they left off? Can I just pass the values back to the survey in a query string?

Thanks,
Tim
