# Returns the inventory transaction with the given identifier.

`GET /inventory/inventory-transactions/{id}`

Group: Inventory › Inventory Transactions · Operation ID: `getInventoryTransaction`

Returns the same fields as GET inventory/inventory-transactions and POST inventory/inventory-transactions/search. A ledger row cannot be changed once written, so a NOT_FOUND means the identifier was never one, not that the row was removed.
