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.

Query Parameters

Parameter Description
rst The flag for respondent’s session end. 1 = Complete, 2 = screenout, 3 = overquota
psid Dynata’s unique identifier that captures a respondent and the specific project identifier. This was passed to you in the survey URL when the respondent goes in.
med The secure variable which Dynata validates before updating the respondent’s status for the session.

The med parameter can be generated as follows:

med = (security_key_1 * pid) – security_key_2

Fields for med calculation

Parameter Description
pid Dynata’s respondent identifier. This is a unique id passed to you in the survey URL when the respondent goes in
security_key_1 A security key provided to you during onboarding. Please do not share this with anyone
security_key_2 A security key (k2) passed to you in the survey URL. This is unique per project
Example for supported endlinks
{
  "endLinks": {
    "complete": "https://api.dynata.com/respondent/exit?rst=1&psid={psid}&med={calculatedSecurityCode}",
    "screenout": "https://api.dynata.com/respondent/exit?rst=2&psid={psid}",
    "overquota": "https://api.dynata.com/respondent/exit?rst=3&psid={psid}",
    "speeding_open_ends": "https://api.dynata.com/respondent/exit?rst=2&qflag=3&psid={psid}",
    "targeting_mismatch": "https://api.dynata.com/respondent/exit?rst=2&qflag=8&psid={psid}"
  }
}
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
