Invoices

A GST invoice is generated once an order is invoiced on our side. It's nested under the order, same as shipments.

Query

query {
  myOrders {
    orderNumber
    salesInvoice {
      invoiceNumber
      netAmount
      gstAmount
      totalAmount
    }
  }
}

Response

{
  "data": {
    "myOrders": [
      {
        "orderNumber": "GB-3801",
        "salesInvoice": {
          "invoiceNumber": "INV3412",
          "netAmount": 2680,
          "gstAmount": 136,
          "totalAmount": 2816
        }
      }
    ]
  }
}

salesInvoice is null until an invoice has actually been raised for the order — check for that before reading its fields.
