Single Use Links

This guide will help you understand how to generate and use single-use links within our application.

Purpose

  • Single-use links (or one-time / disposable links) are URLs that grant access to a survey only once.

  • The primary purpose of single-use links is to assure that no respondent submits a survey twice.

Using single-use links with Formbricks is quite straight-forward:

  1. In the survey settings, toggle "Single Use Link" on:

  2. When you publish your survey, the following modal will open:

Here, you can copy and generate as many single-use links as you need.
