Access: **DESTRUCTIVE** · toolset amazon_sp · family sp.fulfillmentInbound_2024-03-20

Wraps setPackingInformation; poll the returned operationId to SUCCESS. Amazon SP-API · setPackingInformation · POST /inbound/fba/2024-03-20/inboundPlans/{inboundPlanId}/packingInformation Gate: approve — interactive: show the change (Amazon's preview first where one exists), wait for an explicit approve; autopilot: only when the seller's own words asked for this change; otherwise ask. Each grouping keys EITHER by packingGroupId (Box First) OR shipmentId (Split First). After this completes, call fbaInbound_generatePlacementOptions.

| `plan_id` | string | yes | the inboundPlanId (from fbaInbound_createInboundPlan or fbaInbound_listInboundPlans). |
| `package_groupings` | object[] | yes | 1+ groupings, shaped as the Body block below — each keyed by packingGroupId (Box First, from the confirmed packing option) OR shipmentId (Split First), with boxes: 1–5000 box specs, quantity = how many identical boxes. contentInformationSource BOX_CONTENT_PROVIDED carries the box's items; MANUAL_PROCESS and BARCODE_2D boxes carry none. |

## Result
