Understanding response status codes

Response codes are an important concept in the Cint Exchange. They allow a buyer to understand respondent interactions within the survey process. There are two sets of codes that are paired together:

These codes are paired together in the following format: (pre-screener, client-response). For example the response code combination (3,10) represents a respondent having entered and completed the client survey and returned to the Cint Exchange on a complete redirect. We know this because:

  • The pre-screener code is 3, representing the respondent has finished screening and was sent to the client.
  • The client response code is 10, representing the respondent completed the survey.

Client Status Codes

info

Only 10,20,30,33,34,35,40,70,80,110,134 are acceptable codes on redirects from the client survey platform, the rest are declared by Cint Exchange after the respondent returns from the client platform. If a respondent returns in any other status than the ones listed, they will be marked as a 91 in all reports.
