Tip

The invalid_weight_unit error code is returned if you provide an invalid or unrecognised value for unit when specifying the weight of an object such as shipment_contents.

This error code will be returned, for example, if you provide an invalid unit value when specifying the weight of shipment_contents:

{
  "contents": [
    {
      "weight": {
        "value": 2.33,
        "unit": "cm"
      },
      //other properties
    }
  ]
}

The valid values for unit when specifying weight include:

• kg - kilograms
• lb - pounds

Warning

When creating or updating a shipment, all unit values for all weight objects must be the same for all shipment_contents. It is not valid to mix unit values in a single shipment.
