How to create hidden or custom variable using URL query string

A hidden variable using a query string in the URL allows you to pre-populate data in your survey so that your survey respondents are saved from common questions like name and email id.

This is helpful when you circulate to a known audience. Eg. Name and Email-id are known, and you don't have to ask for them again. 

Here's how to do it: 

  1. Go to Settings -> Assignment & Formulas -> Text Variables in a survey or form.
  2. Add the new variables.
  3. Use the recall function'@' to set the values.

  1. Go to Share and Publish.
  2. Click on Customize Link and enter the values. 
  3. Click on Create Custom URL to generate the custom link for your survey. You can also create multiple URLs if needed.

Note: If you have a list of names and emails. Copy the sample URL and generate it by replacing it in Excel. This can be created on your own as well. At the end of the survey, add '?' followed by variable_name = value. Use the & symbol to join multiple variables.

  1. Copy the URL and share it with your audience.
