Hi there,
I was wondering if it was possible to let webflow forms use another post method PHP script while still performing the default webflow post method action (which write any forms sent by the user into those lovely CSV file we can find on the forms administration panel)
My idea is:
Write a script that allows my PHP server to send a confirmation email to anyone who sends a form. Right now, Webflow unfortunately doesn’t allow us to do so. That being said, I would still love having those CSV form file being created like usual.
Thank you very much for your help !
