The GET /api/2026-01/search endpoint now supports additional filter parameters and sort fields when searching for sales (type=sales).

The InventoryLevel response returned by POST /api/2026-04/inventory_levels and GET /api/2026-04/inventory_levels/{product_id} now exposes the active reorder strategy via a reorder_method field, along with updated semantics for the existing reorder fields.

The following endpoints on the 2026-04 API have been deprecated in favour of the new fulfillments resource. They will be removed in the 2026-07 API version.

The 2026-01 API adds support for custom inventory adjustment reasons and stock adjustments. New endpoints allow you to create and manage adjustment reasons, record stock adjustments, and list adjustment history.

The 2026-04 API adds support for managing and reading reorder points. A new endpoint allows bulk upsert of reorder points, and the Inventory response now exposes the active reorder strategy and target.

New 2026-04 Gift Card and Gift Card Transaction endpoints are now available. These endpoints follow the 2026-04 API conventions while delegating to the same underlying gift card business logic.

We are excited to announce a major update to our API versioning strategy. To better support the growing needs of the Lightspeed Retail (X-Series) platform, we are moving from Semantic Versioning to a Date-Based Versioning strategy.
