End Link
After the respondent completes the survey, they should be redirected to a secure exit redirect link. These links give the respondent the proper information and allow Dynata, and you, to properly record and count the status of all the respondents that take your survey. Your survey must be updated and tested with these links before launching the survey.

Example for supported endlinks

"endLinks": {
"complete": "https://api.dynata.com/respondent/exit?rst=1&psid={psid}&med={calculatedSecurityCode}",

}
}Example med calculation
med = (66213 * value for pid ) - security_key_2
For a respondent with pid=1070000026, security_key_2=59931, the value would be:
med = (66213 * 1070000026 ) - 59931 = 70847911661607
