How it fits together
On Tavra you post a study with the survey template and paste your survey's link. When a worker accepts, Tavra opens your link with their assignment reference added as a URL parameter. At the end, your survey either redirects them to the return link Tavra gives you, or shows a completion code they enter on Tavra.
The template names the exact parameter and return link at launch. The Qualtrics settings below are the same either way.
Set up your survey
- In Survey flow, add an Embedded data element at the top and name a field for the assignment reference. Qualtrics fills it from the URL when the field name matches the parameter.
- Add an End of survey element, choose to override the survey options, and pick Redirect to a URL.
- Paste Tavra's return link and append the assignment reference with piped text, so Tavra knows whose response finished.
- Preview the survey with a test reference in the URL and check that it arrives in your data and in the redirect.
Checks that work well
- Attention questions inside the survey, scored by Tavra as gold-standard answers.
- A minimum completion time, so rushed responses are flagged by a fixed rule.
- Screening questions on Tavra before acceptance, so people who don't qualify never start.
