Products are associated with events and support a full item lifecycle: creation, issuance, redemption, transfer, and sales tracking. ## Key Concepts ### Product Types Every product has a `type` that defines its purpose: | Type | Description | | ----------- | -------------------------------------------------------------- | | `admission` | Entry tickets for events (e.g., general admission, VIP) | | `presale` | Early access or presale offers | | `perks` | Vouchers and extras (e.g., drink coupons, merchandise credits) | ### Product Configuration Products offer fine-grained control over distribution and usage: | Field | Description | Default | | --------------------- | ---------------------------------------------------------------------- | --------- | | `stock` | Total available inventory. `null` for unlimited. | Unlimited | | `max_per_account` | Maximum items a single user can hold. `null` for unlimited. | Unlimited | | `redemption_quantity` | Number of times each item can be redeemed before it is fully consumed. | 1 | | `is_transferable` | Whether items can be transferred between users. | `false` | | `is_claimable` | Whether items can be claimed via a direct URL. | `false` | | `min_rep_balance` | Minimum reputation balance required to receive an item. | 0 | | `max_items` | Maximum items in the collection. `null` for unlimited. | Unlimited | | `active` | Whether the product is currently active and items can be issued. | `true` | ### Product Items A **product item** is a single instance of a product issued to a user. Each item has: * A unique sequential `item_id` (also used as the NFT ID if minted) * A `redemption_count` tracking how many times it has been redeemed * An `is_fully_redeemed` flag indicating whether all redemptions have been used * Owner information (user ID, email, name) Items can be issued in bulk — up to **550 users per request** — by providing user IDs, email addresses, or a mix of both. ### Redemption Redeeming an item increments its `redemption_count`. Once the count reaches the product's `redemption_quantity`, the item is marked as fully redeemed and cannot be redeemed again. This supports both single-use items (e.g., event tickets) and multi-use items (e.g., a voucher valid for 3 drinks). ### Transfers When a product has `is_transferable` set to `true`, items can be transferred between users. Transfers are subject to the following rules: * The sender must be the current owner of the item * The item must not be fully redeemed * The recipient must be a user in your project * Self-transfers are not allowed * The recipient must not exceed the product's `max_per_account` limit ### NFT Minting Products can optionally mint an NFT for each issued item by setting `mint_nft` to `true`. When enabled: * A `metadata_uri` is required — a URL pointing to a JSON file with `name`, `image`, and `description` fields * A `chain` must be specified: `AssetHub` (Polkadot) or `WestendAssetHub` (testnet) * Your project wallet must hold at least **2 DOT** (AssetHub) or **2 WND** (WestendAssetHub) to cover on-chain fees * Each item's sequential `item_id` is used as the on-chain NFT ID ### Pricing and Sales Products support optional pricing via the `price` field (a decimal string, e.g., `"9.99"`). When products are sold, the Sales endpoint provides paginated access to order history including order numbers, quantities, unit prices, and buyer details. ## Available Endpoints Create a new product with type, pricing, stock limits, and optional NFT minting. Fetch all products for your project with pagination. Retrieve a single product by ID with full configuration details. Issue items to up to 550 users per request by user ID or email. Redeem an item, incrementing its redemption count. Transfer an item from one user to another. Fetch paginated sales history for a product.
