I don't want to use jotform, Angular, PHP, wordpress, woocommerce, etc.? Just html & javascript. The paypal developer page(s) quickly drop into a black hole of vague assumptions. Everything online is directed to simple buttons for one product or added to wordpress etc. Udemy doesn't seem to have anything either. I have a sandbox setup with my business account. I have successfully loaded my checkout page with the Paypal & Card buttons and figured out how to pass the total cost from my checkout page into the system but I'm stuck there. Testing tells me to enter a valid card number so dummy numbers don't work, although I'm using my sandbox client ID. So just want to know if there is an online course or tutorial which will get me to a working payment system.
