Tip

The duplicate_tags error code will be returned if the same tag value is added to a shipment more than once.

For example, this code will be returned if you attempt to create a shipment and provide a duplicate value in the tags property:

{
  "tags": [
    "my_tag",
    "my_tag",
    "dangerous",
    "high_value"
  ]
}

This request will fail with a duplicate_tags error because the value "my_tag" was provided twice.
