You’ll learn how pre-populated surveys save time, reduce errors, and keep all responses connected to the right participant profile. ### **What is a URL Parameter?** A URL parameter is a small piece of extra information added to the end of a website link. Think of it like a note attached to the link that carries information from one place to another. ### **How EnrollNow Uses URL Parameters** In EnrollNow, URL parameters make surveys faster and easier for participants by carrying over information already collected (such as name or contact details) to be carried into another survey. Benefits of using URL parameters: - Participants don’t have to re-enter the same information. - All responses are linked to the same profile. - Duplicate records are prevented. You can use URL parameters to: - Pass data from **survey to survey** - Pass data from an **email or text message into a survey** Passing data from survey to survey is especially useful during pre-screening.  #### Example: Pre-Screening Workflow - A potential participant completes an **Interest Survey-**a survey to express interest in your study. - Based on their answers, they are directed to complete a **Medical Records Request Form**. - URL parameters pre-fill their name and contact information, linking their responses to the correct profile to eliminate the need to re-enter information. This process: - Saves participant's time - Prevents duplicate profiles if matching fields (First Name, Last Name, Birthday) are mistyped - If the participant doesn’t finish the Medical Records Request Form right away, you can send a reminder email or text later. In that case, URL parameters ensure the form still links back to their correct profile. #### Best Practices for Using URL Parameters - **Global ID can be used alone.** - **Always include the Global ID first as the first URL parameter if including additional parameters.** If the URL breaks after the Global ID, data may not pre-populate, but the participant profile will still be correctly linked. - **Map out the participant journey.** The format of URL parameters will vary depending on how participants moves through this journey.   #### **What information do I need to set up URL Parameters?** When passing data from **survey to survey**, the URL parameters will include:  - The name of the survey question from the first survey - The name of the survey question on the second survey, where you want to populate the data as URL parameters. When passing data from an **email or text message to a survey**, the URL parameters will  include: - The name of the survey question - The name of the variable as URL Parameter NOTE: It is also important to note there are some limitations in the type of data that can be passed from an email or text message into a survey. #### **Step by Step: How to use URL Parameters when linking Survey to Survey** In the example below, we will pass the participant's Global ID(gID), first name, last name, date of birth, and email address in URL parameters. ##### **Sample URL:** #### **![](https://support.enrollnow.io/hs-fs/hubfs/image-png-Sep-18-2025-08-22-54-0189-PM.png?width=670&height=110&name=image-png-Sep-18-2025-08-22-54-0189-PM.png)** 1. Start with the URL of the **second survey** (where data should appear). 2. Add a ? after the URL. 3. Add each parameter in this format:            `QuestionNameOnFirstSurvey={QuestionNameOnSecondSurvey}` 💡 *Tip: Using the same question names in both surveys helps avoid confusion.* #### **How to use URL Parameters from Email or SMS to Survey** In the example below, we will pass the participant's Global ID, first name, last name, and date of birth in URL parameters. **Sample URL:**  ![](https://support.enrollnow.io/hs-fs/hubfs/image-png-Sep-19-2025-12-40-33-4805-AM.png?width=670&height=112&name=image-png-Sep-19-2025-12-40-33-4805-AM.png)**How it works:** 1. Start with the URL of the survey. 2. Add a `?` after the URL. 3. Add each parameter in this format:  `` **NOTE:**  When creating an email template that includes **merge tags** or **URL parameters**, you can now preview the complete message layout — including dynamic merge tag data, text, formatting, and images — to confirm that all participant-specific information is pulled correctly from the Participant Profile Card and displayed as intended. Review the Email Preview article [here.](https://ripple.ripplescience.com/en/knowledge-base/previewing-your-emails?hsLang=en) #### **Email or SMS Limitations and Variable Names** ##### **Not all data can be passed from an email or text into a survey. To learn more about the data elements that can be passed via email and text messages:** - ##### Navigate to **Study Settings** - ##### Navigate to an **Email or Text** tab. - ##### Open an existing or add a new email or text template. - ##### At the bottom of the builder, select ***“Click here to see a list of available variables”*** (refer to image below). - ##### A list will display which **variables** can be used as URL parameters to pre-fill surveys. ![Email and Text URL Parameters](https://support.enrollnow.io/hs-fs/hubfs/Email%20and%20Text%20URL%20Parameters.png?width=570&height=91&name=Email%20and%20Text%20URL%20Parameters.png) - Teams can also opt in to pass **custom variable data** into surveys through emails and texts. This feature must be enabled by the EnrollNow team. If you would like to enable the functionality of passing custom variable data into surveys through emails or text messages, please contact **help@enrollnow.io** for assistance.   - [My Account](https://support.enrollnow.io/en/knowledge-base/my-account?hsLang=en#main-content) -
