post https://api.mintology.app/v1//claim
This endpoint will mint a free NFT to your user's wallet (which can be a Mintable Wallet, or their existing crypto wallet). This is the endpoint you should use for discount coupons, proof of attendance, and in general NFTs which you do not intend to sell.
Note: Separating the mint and claim endpoints will allow you to clearly identify the purpose of each call in your analytics.
