Where should this file go?

Thanks for sharing this snippet! I've tested this code on my Wordpress site, using Code Snippet. It adds the fields to checkout but the custom fields are not being received by Zapier (using a Zap with PMPro as the direct trigger app, not a custom webhook). Have you encountered this issue?
