Track Hubspot Forms with Google Tag Manager

Hubspot forms

Forms created with Hubspot are difficult to track with Google Tag Manager’s native triggers.

I’ll show you how to track only valid submissions of a Hubspot form, and also how to get user data (such as email address) to send to advertising platforms.
