Now you have the collection created and uploaded the files and metadata, it's time to define how you are going to sell the NFTs.
Here we are going to create a sale phase for a pre-sale where we want to sell 1000 random NFTs. We have 4 price tiers and the buyers can select the tier they want to buy. For example, if a buyer want's to get 4 random NFTs they can select the Gold tier and pay 30 Ada.
Generate the sale phase with the price tiers and the links for the four buy buttons.

Response
In the response we can see that each price tier has an associated payment link. Then we copy that link and embeded it in the button. When the buyer clicks on the button a new window with Tangopay will open and once the payment is done the NFTs are sent to the wallet.

Create a button for every payment link and sell the collection on your website.
NFT Drop website
When the buyer clicks on the buy button a new window with Tangopay will be openend and from there the buyer can pay with any of the most used wallets in Cardano.
With this code you can create the collection, upload the tokens and generate the payment links.
