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

How Workers are Approved

(optional) Secret Completion Code that workers must enter to complete the HIT. (Alphanumeric characters excluding numbers 1, 0 and letters I, O, l)

If you are managing your own secret code then you should leave this field blank and check off Custom Code below

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
Note Regarding Dynamic Completion Code
Please be advised that Dynamic Completion Code is designed for Qualtrics studies that do not contain redirects for which the survey URL changes. To test that your survey is properly set up before you launch it, click on your survey's CloudResearch Survey Preview link (in the Dashboard) and test your survey. See our blog post for more details and how to set up Dynamic Secret Code for surveys with redirects.
Setting up the dynamic code by definition means each individual worker will get a unique completion code. To do this on Qualtrics:
  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
  4. Go to Custom End of Survey Message and click new message **In Survey Flow
  5. Enter Secret Key in the Description field. (Next time you can select this message.)
  6. Click the Source button
  7. Paste the following text exactly into the window as shown

    <iframe src='' width='100%' height='200'></iframe>

  8. Click Save

Safety Feature

Automatic grading will only approve Workers and not reject them. Rejections must be performed manually (in the Dashboard) before the "Auto pay workers in" time frame found below. See this blog post for more details.
The time before workers are automatically approved for work (Useful only if no Secret Code is specified and HIT is manually approved)

Worker Requirements

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
