Guide to Madlitics Fields

Understanding where your leads come from is only half the story — knowing how to structure that information is what unlocks actionable insights. Madlitics uses a flexible set of key-value (KV) parameters to pass attribution data from your website into your forms.
This page outlines all available Madlitics fields. We recommend starting with the default fields, which cover the essential attribution data for most businesses. From there, you can expand with secondary fields to capture deeper insights and customize reporting based on your marketing strategy.
Every form needs a set of core Madlitics fields to capture attribution data. These fields run quietly in the background, collecting details like the marketing channel, source, and landing page—without adding any extra steps for your visitors.
When you’re building your form, drag in Hidden Fields for each Madlitics parameter. In the field settings, set the label and default value so they match the correct Madlitics field. For example, to configure the channel field, set the label to channel
and the default value to [channel]
.
Repeat this process for all seven default fields. Once they’re in place, your forms will automatically include attribution data in every submission, giving you a clean and consistent dataset inside your CRM.

Once you’ve set up the core Madlitics fields, you can layer on additional fields to capture more detailed attribution data. These secondary fields aren’t required, but they’re helpful if you want to track things like creative variations, platform-specific click IDs, or custom campaign identifiers. If you’d like to capture Google Ads click IDs, add a field with the label gclid
and default value [gclid]
.
Use these fields selectively—only add what you’ll actually use in reporting. The goal is to enrich your CRM with meaningful data, not overwhelm it with details you don’t plan to analyze.

Once your Madlitics fields are set up, every form submission is paired with clean, consistent attribution data.

Getting attribution right at the form level is a big step toward smarter marketing decisions. From there, Madlitics makes it easy to send this data into your CRM or other tools, so you can analyze performance, optimize campaigns, and confidently invest in what’s working.
