Purchases of Multiple NFTs

If you are using our previous version of embedded checkout, please refer to the old multiple NFT purchases guide

You can enable users to purchase multiple NFTs in a single transaction using either CrossmintEmbeddedCheckout or CrossmintPayButton:

<CrossmintProvider apiKey="_YOUR_CLIENT_API_KEY_">
  <CrossmintHostedCheckout
    lineItems={[
      {
        collectionLocator: "crossmint:_YOUR_COLLECTION_ID_",
        callData: {
          totalPrice: "0.001",
          _quantity: 1, // matches your contract's parameter name
        }
      },
      {
        collectionLocator: "crossmint:_YOUR_COLLECTION_ID_",
        callData: {
          totalPrice: "0.002", 
          _quantity: 2,
        }
      }
    ]}
  />
</CrossmintProvider>

For EVM contracts, ensure the attribute name in callData matches the parameter name in your mint function. For example: If your mint function has the signature: mintTo(address _to, uint256 _amount) then use _amount instead of quantity.
