Ecommerce coupon at checkout functionality (with server side validation)
Ecommerce coupon at checkout functionality (with server side validation) Im building an ecommerce website/webapp using mongodb, express, reactjs and nodejs and I am a little confused on how to make the coupons users can apply to cart on checkout. I know that I would need to verify the coupon and the cart data server-side for security reasons. Any tips, help, guide or resources would be greatly appreciated. Thank you ...
