We want to append certain query parameters to the survey URL (which would be unique to specific groups of respondents) and retrieve those values while handling the PreSurveyPageEvent. Is there any way to retrieve them for this event?
Alternatively, I understand I can use the RespondentDataFoundEvent to get these URL parameters. However, there is some data that we want to retrieve by catching the PreSurveyPageEvent also. Is there any way to store the URL parameters which I retrieve from the RespondentDataFoundEvent in the plugin and use them later while handling the PreSurveyPageEvent?
