I have created a survey with Microsoft forms. I have so far one survey translated to 19 languages, therefore, 19 survey links. I am are planning on distributing these surveys with a company (i.e. Cint). We will distribute the surveys in 45 countries, to 400 respondents per country
The distributing company (Cint) is asking me to obtain a "variable" in order to attach an [ID]-Capture at the end of the survey link (e.g. c=, guid=, respondent= and similar … ). This [ID]-Capture is needed by the company to fill it in automatically with a 38-digit code to identify the panelists/respondents.
