Hi, for Stripe payments, the FF documentation says QUOTE From this tab, you can redirect users to a Stripe checkout or thank you page after submitting their form. Or, go one step further and email them an invoice following their purchase. UNQUOTE Link: https://formidableforms.com/stripe-payment-options-wordpress/ However, I do not find any further details on both steps, i.e. 1) how to redirect to a stripe page for payment, and 2) how to automatically email an invoice to the user after purchase. Can anyone point me to a documentation which contains further explanation on how this can be done in FF?
