Sales

What is a Sale?

It is a way of selling NFTs faster without creating a sale phase and price tiers. With this functionality, you just have to select the NFTs you want to sell, and it will generate an address and a payment link. If the buyers send Ada to that address, they will get the NFT back, and if you use the payment link, then your buyers can make the payment through Tangopay (payment gateway).
Parameters
  • type: fixed | random. (Mandatory) Use fixed for selling a particular token or token list identified by the id. Use random for random sales, it will pick random tokens from the collection.
  • reservation_time: (Mandatory) Reservation time in seconds. This timer defines how long an NFT will be reserved once a potential buyer starts the buying process. During this time interval, the NFT won't be available for sale. No other buyer will be able to create a new reservation. If the payment is not received and this timer expires, then the NFT is ready for sale again, and it can be reserved by another buyer.
  • price: (Mandatory) Individual token price in Lovelaces (1 ADA = 1000000 Lovelaces).
  • tokens: (Optional) Array of token IDs. Used in fixed sell.
  • quantity: (Optional) Amount of NFTs to sell in a random sale.

Fixed Sale Example

Here we are going to create a sale with two items for 200 Ada. Thus the buyer pays that amount and receives both NFTs. You can also create a sale for individual NFTs, including only one token id.
fixed sale
First we need the ids of the items we want to sell. For that we have to list the NFTs in the collection with the following endpoint.
HTTP
cURL
GET /<app-id>/v1/nft/collections/<collection-id>/tokens HTTP/1.1
Host: cardano-testnet.tangocrypto.com
x-api-key: <your-api-key>
curl --location --request GET 'https://cardano-testnet.tangocrypto.com/<app-id>/v1/nft/collections/61844bfbb75c4782085f01fd/tokens \
--header 'x-api-key: <your-api-key>'
It will return this:
