We need to integrate payment processing via upc.ua to a landing page (static HTML).
The page sells one product via a simple form.
– send email to a client about an order (with short details);
– open payment system page;
– send a “thank you”/”payment rejected” email to a client with a result of the payment process;
– all emails also go to the seller.
– emails have to be HTML-formatted (simple design).
Additional documentation and support available under request.
