The Products API lets you create digital products and distribute them to your users. Products cover everything from event admission tickets to drink vouchers, VIP perks, and NFT-backed collectibles — with full lifecycle management for issuance, redemption, transfer, and sales tracking.

​
How Products Work

Create Product → Issue Items to Users → Redeem at Event → (Optional) Transfer Between Users
Every product belongs to an event and has a type that defines its purpose:
TypeUse CaseExample
admissionEntry ticketsGeneral admission, VIP pass
presaleEarly access offersPresale tickets, early bird deals
perksVouchers and extrasDrink coupons, merch credits, backstage access

​
Product Items

A product item is a single instance of a product issued to a user. Think of a product as the template (e.g., “General Admission Ticket”) and items as individual copies given to specific users. Items support:
  • Sequential IDs — Each item gets a unique item_id (also used as NFT ID if minted)
  • Multi-use redemption — Configure redemption_quantity for items valid for multiple uses (e.g., a voucher for 3 drinks)
  • Transfers — Allow users to send items to other users (when is_transferable is enabled)
  • Batch issuance — Issue to up to 550 users per request

​
Configuration Options

Products offer fine-grained control over distribution:
FieldWhat it doesDefault
stockTotal available inventory (null = unlimited)Unlimited
max_per_accountMax items per user (null = unlimited)Unlimited
redemption_quantityTimes each item can be redeemed1
is_transferableAllow transfers between usersfalse
is_claimableAllow claiming via direct URLfalse
priceProduct price as decimal string (e.g., "49.99")—
activeWhether items can currently be issuedtrue

​
NFT Minting

Products can optionally mint an NFT on the Polkadot network for each issued item. When enabled:
  • Set mint_nft: true when creating the product
  • Provide a metadata_uri pointing to a JSON file with name, image, and description
  • Choose a chain: AssetHub (mainnet) or WestendAssetHub (testnet)
  • Your project wallet needs at least 2 DOT (or 2 WND on testnet) for on-chain fees
  • Each item’s sequential item_id becomes its on-chain NFT ID
