Inventory Manager API · items
The SKU's activity log
GET /items/{sku}/events
The SKU's activity log: every journalled event that touched it — its creation, each configuration change, every stock movement, the transfer lines that carried it, and the catalog events that priced or recomposed it — newest first, each with its actor and occurredAt.
A composite SKU (a kit) has no item but has a log: the events naming the kit itself merged with every component's, since a part moving is what changes what the kit can promise. Paged by sequence, back to the SKU's first event: limit is 1–500 (100 when omitted), and a page carries next while older events remain — pass it as before for the next page. A cursor rather than an offset, so a movement landing mid-read never shifts a page. 404 ItemNotFound for a SKU that is neither an item nor a kit of the organization's.
Access
Requires stock:read or products:read or receiving:read or purchasing:read or allocations:read.
Any one of these scopes is enough.
How scopes come from roles: Scopes and roles. Getting a token: Authentication and app tokens.
AI agent tool
Agents call this as inventory_item_history (Inventory: Item history), in the stock toolset. It only reads.
Connecting an agent: AI agents.
Example
The three latest movements; pass next as before for older ones.

}The panel writes this call in other languages. It does not send it: Manifold's APIs do not take calls from a web
page on another site, so run the call from your own code or terminal. The whole API as OpenAPI: inventory-manager.openapi.json. Base URL https://inventory.getmanifold.io.
