Title of the survey that will be displayed to workers
A description of your survey
The URL of your survey
Query String Parameters
By default, CloudResearch will add the following query string parameters to your URL so you can take advantage of them in your data collection. The parameters are: workerId, assignmentId, and hitId.
  • workerId-The MTurk Worker ID
  • assignmentId-A unique ID that Amazon generates for a worker taking your HIT
  • hitId-The ID of your HIT

For example, if your Survey Link is, we will add the above parameters to the URL, so the final URL might look like You can then take advantage of these parameters by setting up Qualtrics Embedded Data
Selecting this option will not add workerId, assignmentId and hitId to your Study link. This feature is useful if your Survey platform does not support additional query string parameters in the url

Please note that CloudResearch will automatically approve participants based on the completion code that you select below. Your completion code will need to be either a Dynamic Code or a Fixed Code.
Secret Completion Code that workers must enter to complete the HIT. (Alphanumeric characters excluding numbers 1, 0 and letters I, O, l)

Note: Your External Secret Completion Code must be prominently displayed on the last page of your survey and without ANY punctuation before or after it like this:
Secret Completion Code: AJFHBG897

  1. Create or Edit a Survey
  2. Go to the End of Survey section, located after the final block in the survey, and click the "Survey Termination Options"
  3. In the Survey Termination Section: Click on Custom end of survey message... **This can also be accessed from Survey Flow

Worker Qualifications

Note Regarding HIT Approval Rate
When you set HIT Approval Rate (e.g. 80-100%) CloudResearch automatically sets Number of HITs Approved to be at least 100 since MTurk assigns an Approval Rate of 100% to Workers who have completed less than 100 HITs (MTurk API Reference).
HIT Approval Rating: 90-1000000%
Worker needs to have completed between 100-1,000,000 HITS
