CTA pop up form customisation

[lstepany]

Can anyone help me to find a documentation (if any) for  form customisation? It was possible to customise
onFormSubmit event in the form embed code with old forms:
 https://legacydocs.hubspot.com/docs/methods/forms/advanced_form_options

However  I cannot find how to customise new pop up forms:

Hey @lstepany this isn't currently possible. The form embed code you've linked isn't the "old" one, it's the form embed code. When embedded in a CTA you don't have access to the form embed code to add the callbacks. 

The only way to customise this would be to use your form embed code and create a custom pop-up yourself as CTAs wouldn't give you access to this.

Thanks for reply @TomM2 !

Justin forewarded this in the HubSpot's Slack API channel. It proofed to work pretty wall, I was able access the pop-up form data and to add any function I need 😎

Interesting thanks for sharing @lstepany 

Has HubSpot confirmed CTA markup will stay consistent? In the past I've seen markup change when it's not publicly shared, particularly with new products.

That's avalid point I actually haven't checked that. Thanks! 🙂
