Inventory

List inventory transfers (warehouse, intercompany, FBA inbound)

Returns a paginated list of inventory transfer records for the entity. A transfer is visible when EITHER endpoint matches the active location (Pattern A on inventory_transfers.location_from_id OR location_to_id), mirroring the bin-movements operator mental model “show me every transfer that touches LOC-X”.

Layer 4 location isolation (NEW-GAP-API-V1-LIST-X-LOCATION-ID-SWEEP, 2026-05-17): the wrapper applies the X-Location-Id request header first, then the location_id query param (header takes precedence). When neither is set, the response is entity-wide (admin view). location_from_id and location_to_id are NOT NULL in the schema, so there is no NULL-universal carve-out for transfers.

Filter set: status, transfer_type, search (transfer_number prefix + trigram similarity). The page also returns a stats object with rollups for active, pending_approval, in_transit, and closed_today counts scoped to the same location filter.

Requires inventory:read scope.

Authorizations

Authorization

string

header

required

API key issued per entity via Settings > Developers > API Keys. Each key carries scopes (e.g. orders:read, products:write). Bearer token format: Authorization: Bearer ark_live_ent_Test keys use ark_test_ent_. Both are issued per entity via Settings > Developers > API Keys.

Headers

X-Location-Id

string<uuid>

Active location pill (Layer 4 isolation). Takes precedence over the location_id query parameter. The wrapper enforces the precedence ladder header > qp > admin entity-wide, matching listOrdersV1 / listReturnsV1 / listPackagesV1 / listLabelsV1 / listSerialsV1.

Query Parameters

location_id

string<uuid>

Filter to a single warehouse location (Layer 4). Used only when X-Location-Id is absent. A transfer is included whenever its location_from_id OR location_to_id matches.

location_ids

string

Comma-separated list of location UUIDs (multi-location restriction; user_locations gate). When supplied, supersedes both location_id and X-Location-Id. Each transfer is included when EITHER endpoint sits in the array.

status

enum<string>

Available options:

draft,

submitted,

pending_approval,

approved,

rejected,

in_transit,

working,

shipped,

receiving,

received,

closed,

cancelled,

all

transfer_type

enum<string>

Available options:

internal,

intercompany,

fba_inbound,

all

string

Transfer number prefix match plus trigram similarity (> 0.3).
