# Add hidden fields to ActiveCampaign Forms

ActiveCampaign allows you to build forms and capture leads on your website.

With LeadSources, you can **track the source of the leads generated in ActiveCampaign**, alongside other lead source data.

In this guide, we will show you **how to add hidden fields in ActiveCampaign**to start capturing the source of your leads.

## Step 1: Create custom fields

From your ActiveCampaign account, click **Contact** > **Fields**

Repeat these steps for all the other fields:

| **Custom field name** | **Default value** |
| --- | --- |
| Source | [source] |
| Campaign | [campaign] |
| Term | [term] |
| Content | [content] |
| Landing page | [landingpage] |
| Landing page subfolder | [landingpagesubfolder] |

## Step 2: Add the hidden fields

**Context:** In this step, we add the hidden fields to our form to store the lead source data captured by LeadSources.

First, open your ActiveCampaign form: from your ActiveCampaign dashboard > Click **Website** > Click **Forms** > Open your form.

Scroll down on the right panel to find the **Custom Fields**section > Find the **Channel**field > Drag it in your form.

- Landing page subfolder

Your form should look like this:

You are all set!

LeadSources will **capture****and store the lead data****in these 7 hidden fields**. This data will be visible from the ActiveCampaign form submissions page, alongside the form's responses (name, email, etc.).
