I am planning to have a preceeding questionnaire before I ask respondents to do something in a webshop and then have them return to the (ideally same) questionnaire again.
So far the best solution I can come up with is to have two surveys. Meaning: end the first survey completely. In the Out-Link pass a token or payload (I might not want to work with participant tables but rather allow anyone to participate, so token might not be possible). Keep the token/payload saved, while they do things in the shop and pass it again to the second survey start. Later I would have to join the responses then manually.
Obviously it would be more convenient to have the participants just 'leave' and be able to return on the push of a 'return' link, opening up the same questionnaire. This way I could have one response and not two and a more 'seamless' structure.
So I guess my question is: is there an element that I can put into the questionnare to send people out, that automatically creates a way to continue once they return? Like the final link with payload, but 'inbetween'. Or a 'forced pause' with out-link that will proceed to the next question on return. At best I would be even able to accept new information from the Shop system via URL-Parameter here.
