I am having someone develop a gateway for me so a website can accept my custom token (nootropicoin built on WAVES) as payment. My developer is asking how to code the exchange rate (nootropicoin to WAVES to USD) so it shows the correct amount in shopping cart.
Similar to this, only using Python.
I am not sure I am asking the correct question.
When a customer buys a product from a website, adds to shopping cart, and chooses to checkout. They can choose credit card or bitcoin. I want them to be able to choose nootropicoin as well. But I need real-time conversion of the amount of USD converted to Nootropicoin.
You can see example buy placing fake order on nootropics.com - which accepts bitcoin.
