Automated email distribution of daily diary survey

Hello @Laian , You have a single survey and you are sending this survey over a period of 21 days via retake link. Step 1: Create 21 web service of create-distribution with message as a retake link. Add sendDate to 21 web service changing send date using formula: `${date://OtherDate/Y/+2%20day}-${date://OtherDate/m/+2%20day}-${date://OtherDate/d/+2%20day}T08:00:00Z` The above formula will send the distribution on the second day from the date on which the survey is filled for the first time, similarly just modify the number 2 to 3 and so on. Also, every time the participant finishes the survey update the response id in the contact list, this updation is because we get updated response id every time i.e the participant can see 19th day response on 20th. So the retake link will be `...url/jfe/form/<surveyId>?Q_R=<Piped responseId>&date=<pipe the sendDate of the same distribution>` Step 2: When a participant fill the survey for the first time, update an embedded data in the contact list as "FirstSurvey"="Finished". Fetch "FirstSurvey" embedded data using authenticator Now apply branch logic before 21 web service as -if "FirstSurvey" is not equal to "Finished" do web service. So that the distribution is scheduled only once. Step 3: The date that we will pipe in the retake url(Step 1) will help to expire the survey manually i.e at the start we can check using branch logic that if date and current date are not same then terminate the survey using end of survey element and check "Do not record survey response " in the customize End of survey options. So that only valid responses are there in data and analysis
