Re-running pre-filling and post-filling for survey questions

If you’ve launched your survey containing hidden questions that use pre-filling or post-filling to import contact metadata, but certain contact fields were added or changed after the survey already went live, you can re-run the pre-filling and post-filling for these hidden questions to update the responses with your new information.

To re-run pre-filling and post-filling for survey questions, complete the following steps.

  1. Select Actions from the top of the survey editor. Then select Re-run prefill/postfill.
  1. From the side panel, select which questions for which you want to re-run the pre-filling/post-filling.
  1. Select Re-run prefill/postfill.
  1. Select Re-run prefill/postfill from the confirmation pop-up.

The pre-fill/post-fill will be re-run within 24 hours for all questions you selected. The existing pre-filled/post-filled answers will be overwritten. For this reason, any changes you make to your survey while the re-run is in progress may result in your survey changes being overwritten.

Important notes

  • You can only re-run the pre-filling/post-filling for questions where the pre-fill/post-fill was set up using CSL or by selecting contact fields from the available dropdowns. You will not be able to rer-un the pre-filling/post-filling for responses that were filled using query string parameters.
  • You can only re-run the pre-filling/post-filling for hidden questions. This eliminates the risk that you will override updated information while re-running the pre-fill/post-fill. For example, say you have a question in your survey asking about for participant’s location and you have used pre-filling to select the participant’s location. Once the participant views the question, that participant sees that the location is incorrect (because the participant moved since the original data was collected). The participant overrides the pre-filled question so that the current location is updated and the data is corrected. If you re-ran pre-filling for this question, it would override the participant’s selection and would populate the outdated location information. For this reason, re-running the pre-fill/post-fill is only allowed for hidden questions.
