Wholesale API v2.31.0 (2026-10-17)

Version 2.31.0 of the Le New Black Wholesale API v2 is live. This announcement recaps the versions released since 2.28.0.

The release notes of every version, and the OpenAPI file of each one, are now on the developer portal: Wholesale API v2 versions.

What may need a change in your integration

A rejected filter answers 400 (2.28.0). A query parameter whose value cannot be honoured used to be ignored, and the full listing came back. The API now answers 400 and names the parameter.
Price list codes on products (2.28.1). variants[].prices[].price_list_code carries the code of the price list. It used to carry its currency, now returned in currency_code.
Invoice filters (2.31.0). GET /invoices now applies its date and status filters, which were ignored until now. status takes the payment statuses proforma, open and paid. confirmation_time_from and confirmation_time_to are removed and answer 400.
Date filters ending in _to (2.31.0) include their whole day when given as a bare date.

API keys managed by the brand (2.30.0): create, name and revoke your keys under Settings › API, one per integration, read-only when the integration only reads.
order_time on orders, a published filter on products, and price_list_code documented on prices.

price_total and price_total_prediscount on orders: use amount_total and amount_order.
order_scope_order_mode and order_scope_product_minimum on promotions: removed in 2.32.0.

The details are in the release notes of 2.28.0, 2.28.1, 2.30.0 and 2.31.0.
