New HubSpot Form Builder – How to Trigger API Call and Redirect After Submission?

[LeoRebelatto]

I'm integrating a HubSpot form with my app's trial registration. After the user submits the form, I need to make an API call, check the response, and redirect the user to a custom page based on the result.

With legacy forms, I could use form submission events to handle this. But with the new form builder, those events aren't triggering. How can I achieve the same behavior with the new form setup?

Hi @LeoRebelatto,

The new form builder now has a new set of global form events.

Here is a sample for listening for a successful form submission:

window.addEventListener('hs-form-event:on-submission:success', (event) => {
  console.log('User successfully submitted the form!');
});

Hope this helps!
