zettle

zettle_create_product

WRITE: add a new product to the Zettle product library (it appears in the POS and, if enabled, the online store). Not idempotent: calling twice creates two products. Needs READ:PRODUCT and WRITE:PRODUCT. vat_percentage must be one of the VAT rates enabled in the merchant's Zettle settings. Prices are in the smallest currency unit. POST /organizations/self/products.

zettle_get_account

The Zettle user and organization this API key belongs to (uuid, organizationUuid). GET oauth.zettle.com/users/self.

zettle_get_account_balance

The merchant's Zettle account balance (totalBalance in the smallest currency unit, currencyId). LIQUID = money available for payout; PRELIMINARY = payments not yet settled. Optional point in time. Needs READ:FINANCE. GET /v2/accounts/{LIQUID|PRELIMINARY}/balance.

zettle_get_library

The product library together with its discounts (name, amount or percentage), paginated. Returns products, discounts and next_offset (pass it back as offset). Needs READ:PRODUCT. GET /organizations/self/library.

zettle_get_payout_info

Payout information of the LIQUID account: totalBalance, currencyId, nextPayoutAmount, discountRemaining and payout periodicity. Needs READ:FINANCE. GET /v2/payout-info.

zettle_get_product

One product by UUID with all variants, prices, VAT, category, images and online-store data. Needs READ:PRODUCT. GET /organizations/self/products/{productUuid}.

zettle_get_purchase

One purchase (sale or refund) in full by its purchase UUID (the purchaseUUID1 field of zettle_list_purchases; the older short purchaseUUID is deprecated and not accepted): line items, VAT, payments, refund links. Needs READ:PURCHASE. GET /purchase/v2/{purchaseUuid}.

zettle_get_stock

Stock balances per product variant (balance, low-stock level and alert, last update). With inventory_uuid: that STORE inventory only; without: all stores. Only products with inventory tracking enabled appear. Needs READ:PRODUCT. Page with next_cursor. GET /v3/stock or /v3/stock/{inventoryUuid}.

zettle_get_stock_for_products

Stock balances of a few specific products in one inventory (read-only lookup, nothing is changed). Needs READ:PRODUCT. Page with next_cursor (send the same product_uuids again). POST /v3/stock/{inventoryUuid}/products with the product UUIDs.

zettle_list_account_transactions

Transactions (payments, fees, payouts, adjustments) in the LIQUID or PRELIMINARY account between start and end (end exclusive), with timestamp, amount (smallest currency unit, can be negative), type and originating transaction UUID. Needs READ:FINANCE. Page with next_offset. GET /v2/accounts/{account}/transactions.

zettle_list_categories

List the product categories (uuid, name). Needs READ:PRODUCT. GET /organizations/self/categories/v2.

zettle_list_inventories

zettle_list_products

List the products in the POS product library with variants (SKU, barcode, price, cost price, VAT), category, online status and ETag. Zettle returns the whole library at once; this tool slices it with limit/offset and filters by name. Needs READ:PRODUCT. Prices are in the smallest currency unit. GET /organizations/self/products/v2.

zettle_list_purchases

List POS purchases (sales and refunds) with amount, currency, timestamp, products, discounts, payments, refund info and the cashier. Needs READ:PURCHASE. Amounts are in the smallest currency unit.
