Hidden field

The Hidden field lets you collect data silently in the background — without showing anything to customers on the form.

It’s one of the most powerful fields because it helps you track where submissions come from, which page or product, and extra metadata without asking users to fill it in.

✅ When should I use a Hidden field?

Use a Hidden field when you want to:

• Track page URL or page title

• Capture product info (title, vendor, type)

• Save UTM parameters (marketing campaigns)

• Pass values between fields

• Store internal notes or tags

• Send extra data to email, integrations, or Shopify

Note: Customers never see this field on the form.

📈 UTM tracking (marketing campaigns)

Common UTM variables

• {{-utm.medium-}} → cpc, email

• {{-utm.campaign-}} → summer_sale

• {{-utm.content-}}

• {{-utm.term-}}

Example Hidden field label: utm_source Assign value:

{{-utm.source-}}

Result: You know exactly where each submission came from.

🔗 Capture values from other fields

You can also store values entered by customers.

Example

Hidden field label: Customer email Assign value:

{{email}}

This is useful when:

• Sending data to integrations

• Reusing values in emails

• Creating internal references

📧 Set hidden email address

You can use a Hidden field to store an email address and then use it to send admin notifications conditionally.

This is useful when:

• Different submissions should notify different teams

• Each location or department has its own email

• You don’t want users to choose or see the email field
