Direct checkout to Gutenberg forms
WooCommerce Cart & Checkout Action links JetFormBuilder forms to WooCommerce payments. It can perform the ‘Add to Cart’ action for a single product and redirect to the Checkout page. Add, edit, and shuffle the Checkout fields on the Thank you page, apply custom settings to them, and display only those order details you find noteworthy. There’s a possibility to pre-fill the Checkout fields after the redirect as well.
