I’m posting form data from my normal pages to Pardot via a ‘post to URL’ & webhook.

I want to do the same for my AMP pages.

The documentation says that webhook integrations work on AMP pages but any form I put on an AMP page is not giving me an option to post to url - just ‘show form confirmation dialogue’, ‘go to url’, or ‘open url in lightbox’.

Thanks in advance for any help you can give - apologies if this question has been answered elsewhere, I did look but couldn’t find any existing answers.
