GTM Form Tracking Template for FormAssembly

A GTM template for the full FormAssembly form lifecycle: view, start, step, submit, error, consent-gated straight into the dataLayer. Multi-step and modal forms, SPA-aware, OneTrust consent. Open source under Apache-2.0.

Clean form tracking for FormAssembly, with no data collection of its own and no US tooling. The template loads a small runtime and writes the form lifecycle, consent-gated, into the dataLayer.

Asked often

Does the template collect any data of its own?

No. It only runs `dataLayer.push`, with no network calls of its own and no external endpoint. What happens to the events is up to your own GTM tags.

Does it work with multi-step and modal forms?

Yes. The template reports step changes as `step_N` and treats forms inside modals like regular forms, including after SPA navigation without a page reload.

Which consent platform is supported?

OneTrust via `OptanonConsent` is the default, and the consent groups are configurable. In most setups analytics sits on `C0002`.

Documented is not measured.
