Inventory Manager API · transfers

Withdraw the transfer

POST /transfers/{transferId}/cancel

Anything still in transit returns to the source rather than vanishing — a cancelled van still has stock in it. 409 TransferNotInState once it has been fully received; Appends inventory.transfer-cancelled. Idempotent by state: a transfer is cancelled once, so a retry on a cancelled transfer is acknowledged and appends nothing (a second reason is ignored).

Access

Requires stock:write.

How scopes come from roles: Scopes and roles. Getting a token: Authentication and app tokens.

Retries

Idempotent by state: a transfer is cancelled once, so a retry on a cancelled transfer is acknowledged and appends nothing (a second reason is ignored).

Why every write carries a key: Idempotency and retries.

Facts appended

  • inventory.transfer-cancelled

What a fact is: Facts and the journal.

AI agent tool

Agents call this as inventory_cancel_transfer (Inventory: Cancel transfer), in the stock toolset. It is marked destructive, so the agent asks before running it.

Connecting an agent: AI agents.

Example

Cancel after a short receipt: the unit still in transit goes back to Main.
