Endpoint: GET /api/v1/inventory/stock-movement/{sku}

Full URL: https://api.spreetaileu.com/api/api/v1/inventory/stock-movement/{sku}?start_date=2026-08-01&end_date=2026-08-21

Returns the total stock movement for one SKU between start_date and end_date: units in (stock_in), units out (stock_out), the net change (net_movement, can be negative), the number of movement events, and a per-warehouse-location breakdown.

Computed live from warehouse movement history at request time, so the window may include today, and full ISO timestamps are accepted for sub-day precision (date-only values mean start-of-day / end-of-day UTC). Expect a response time of a few seconds.

The {sku} is your own SKU (case-insensitive). Returns 404 if the SKU does not resolve for your account.

Accuracy notes

Accuracy is bounded by how far back movement history is retained — earliest_history_date shows the oldest movement visible, and a start_date older than it may undercount. A transfer between two of your locations counts as an "out" at one and an "in" at the other, so gross totals include transfers while net_movement is unaffected. history_available: false means the SKU has no movement history to read.
