Processing callbacks

During picking and placing, oneGRID Cloud confirms every completed step to the adapter. The adapter can acknowledge the step — and, when the external system wants to change the running order, respond with a work order update that oneGRID Cloud applies immediately. All responses use the response envelope; see the integration lifecycle for where these callbacks sit in the flow.

POST /WorkOrderProcessing/ConfirmWorkOrderStep

One step of single-order processing (a pick or place confirmation) completed.

Request (pick step)

  "itemUnitOfMeasure": 0,
  "amountToConfirmPickingSummary": {

      }
    ]
  },
  "updateWorkOrderRequest": null
}

Response — 200 (acknowledged, no update)

  "data": { "updateWorkOrderRequest": null }
}

Body property	Type	Meaning
storageName	string	Storage where the step happened.
userEmail	string	Operator who confirmed the step.
workOrderNumber	string	Work order number.
workOrderExternalIdentifier	string	External system's work order ID.
workOrderExternalData	string	Customer-specific data (JSON string).
workOrderDescription	string	Description of the work order.
alternativeStartNumber	string	Alternative code the order can be started with.
workOrderTypeName	string	Work order type.
requestId	number (integer)	oneGRID-internal ID of the request line.
requestType	number (enum)	0 Ignored, 1 PickItem, 2 PlaceItem. The enum also defines 3 RelocateItem, but relocation steps are not confirmed to the adapter, so it does not occur here.
requestExternalIdentifier	string	External ID of the request line.
requestRemainingAmountInBaseUnitOfMeasure	number (integer)	Remaining amount, in base unit.
requestAmountInBaseUnitOfMeasure	number (integer)	Requested amount, in base unit.
updateWorkOrderRequest	object	The current update model — see Work order updates.
itemNumber	string	Item number.
itemNames	array	Localized item names: { languageIsoCode, name, isDefault }.
itemUnitOfMeasure	number (enum)	Unit of measure of the item — values as in the WorkOrder object.
amountToConfirmPickingSummary	object	Pick confirmation breakdown — set for pick steps. Carries locationName and containersBreakdown: one entry per container the pick was distributed into (a null container code stands for a virtual container).
amountToConfirmPlacingInBaseUnitOfMeasure	number (integer)	Amount confirmed for a placing step, in base unit.

Response data: { updateWorkOrderRequest } — null when no update is needed. Result values: 0 InvalidInput, 1 Success, 2 OperationFailed, 3 AdapterApiClientFailed, 4 AdapterNotDefined.

POST /CartWorkOrderProcessing/ConfirmWorkOrderStep

The same handshake for multi-order picking with a PickCart. The body is identical to single-order processing except:

• the summary property is named amountToConfirmSummary, and
• there is no placing amount — cart processes only pick.

Response data: { updateWorkOrderRequest } — null when no update is needed. Result values: 0 InvalidInput, 1 Success, 2 OperationFailed, 3 AdapterApiClientFailed, 4 AdapterNotDefined.

Work order updates

When the adapter returns a non-null updateWorkOrderRequest, oneGRID Cloud applies it to the running work order — this is how the external system reshapes an order mid-process (for example after a stock correction).

Response — 200 (with an update: one line reduced, one cancelled)
