Auto-Populate Form Fields with a Query String

You can automatically fill in form fields by adding query strings to the URL of your landing page. This allows you to pass values like name, email, or other data directly into the form without requiring users to type them manually. This also works when the landing page is embedded on your website.

Common use cases include storing UTM parameters (e.g. utm_source=google) for campaign tracking, passing referral or affiliate codes (e.g. ref=partner123), and pre-filling known user data when linking from emails or other forms to save their time. You can also use query strings to carry data between pages or forms on your site.

How to auto-populate fields

1. From the Pages main menu select the campaign you want.
2. Navigate to the Form tab and click to edit the field you want to auto-populate.
3. In the Advanced tab check the option Allow field to be populated dynamically.
4. In the Parameter Name field, enter a custom name—this will be the key used in the URL query string.

Here is an example if you want to populate an email field. In the following example the Parameter Name is the email but you can enter whatever you want.

You can also populate multiple fields at once by adding multiple parameters using the & symbol.

This also works when the landing page is embedded on your website—just add the query parameters to the URL of the page where the form is embedded.

Choice-based fields

For fields that allow multiple choices—such as dropdowns, radio buttons, checkboxes, quizzes, or surveys—it’s recommended to enable the Show Values option and assign a custom Value to each choice. These values can then be used in the query string to pre-select a choice when the form loads.

Here is how you can populate the value in the following example:

Some fields, like Quiz and Survey fields, generate values dynamically and do not offer the Show Values option. In those cases, you’ll need to inspect the HTML of the live form using your browser’s developer tools. Locate the value attribute of the choice you want to pre-select and use that in the query string.
