Membership and receipt NFTs via API
Issue utility NFTs for access, licenses, and receipts. Mode A mints from NxtGateW after you confirm payment; Mode B indexes a mint you already broadcast.
The challenge
Product teams want on-chain membership without standing up contracts, indexers, and webhook plumbing for every launch.
The solution
Self-serve NFT collections under your API keys. Same nft.minted webhook whether you mint through the platform or import a tx hash.
How it works
- Create a collection and choose membership, license, or order receipt semantics.
- After deposit / payment confirmation, call mint (Mode A) or import by tx (Mode B).
- Workers confirm on Polygon or Ethereum and publish public metadata JSON.
- Your webhook receives nft.minted; unlock access in your app.
What you get
- Soulbound memberships and revocable licenses.
- Works alongside deposit wallets — pay then mint.
- Compatible with wallets that speak WalletConnect / standard EVM viewers.
