Hidden variables let you show one discount code per respondent on the end page after a survey, quiz, or test—ideal for post-purchase thank-yous, research incentives, or loyalty rewards. You prepare codes in your store or marketing stack; Responsly displays whatever value you pass in the link.
You need to prepare the discount codes yourself – Responsly does not generate them automatically.
The same URL pattern works for any per-person token—see Unique codes for each respondent.
How to show a discount code on the end page
Go to Settings → Hidden variables in your survey.
Add a new hidden variable. In this example, the variable represents a promo code.
When editing questions and descriptions, click $ to insert a variable into the content.
In this case, insert the variable into the end page so the code appears in the thank-you message.
Back in Hidden variables, copy the survey URL that includes the variable name.
The original placeholder variable is usually just X.
In the URL you pass to respondents, you replace that placeholder with the actual discount code value.
As a result, when a respondent finishes the survey and lands on the end page, they’ll see their personal promo code:
For welcome-screen personalization, see Greeting the respondent. For other end-screen layouts, see End page of the survey.
