DhlFreightApi

A Ruby gem wrapper for the DHL Freight API.

Installation

Install the gem and add to the application's Gemfile by executing:

bundle add dhl_freight_api

If bundler is not being used to manage dependencies, install the gem by executing:

gem install dhl_freight_api

Usage

Initialize the client with your DHL Freight client-key:

client = DhlFreightApi::Client.new(
  "YOUR_CLIENT_KEY",
  prod: false # false => test, true => production
)

Environment Domains

  • prod: false uses https://test-api.freight-logistics.dhl.com
  • prod: true uses https://api.freight-logistics.dhl.com

Error Handling

API failures raise DhlFreightApi::Error.

begin
  client.shipment_booking.create(payload)
rescue DhlFreightApi::Error => error
  puts error.message
  puts error.response_http_code
  puts error.response_body
end

The wrapper raises on:

  • non-2xx HTTP responses
  • business validation responses with status: "Error" from ShipmentBooking (even when HTTP is 200)

Shipment Booking

Create a shipment booking:

payload = {
  "id" => "",
  "productCode" => "107",
  "totalNumberOfPieces" => 1,
  "totalWeight" => 10,
  "totalVolume" => 0.05,
  "references" => [{ "qualifier" => "CU", "value" => "Elin000123" }],
  "payerCode" => { "code" => "001" },
  "parties" => [
    {
      "id" => "111111",
      "type" => "Consignee",
      "name" => "Consignor Company AB",
      "address" => {
        "street" => "Gustav III:s Boulevard 18",
        "cityName" => "Solna",
        "postalCode" => "16973",
        "countryCode" => "SE"
      },
      "phone" => "+46701234567",
      "email" => "[email protected]"
    }
  ],
  "pieces" => [
    {
      "packageType" => "PKT",
      "numberOfPieces" => 1,
      "weight" => 10,
      "volume" => 0.05,
      "length" => 30,
      "width" => 20,
      "height" => 15
    }
  ]
}

booking = client.shipment_booking.create(payload)

puts booking.status
puts booking.transport_instruction.id
puts booking.raw

Request print documents by shipment IDs:

payload = {
  "shipmentIds" => ["2906221086"],
  "options" => {
    "label" => true,
    "shipmentList" => false,
    "waybill" => false,
    "guarantee" => false,
    "returnLabel" => false,
    "licensePlateBarCode" => "GS1",
    "pageOptions" => {
      "pageType" => "Label",
      "marginLeft" => 0,
      "marginTop" => 0,
      "padding" => 0
    }
  }
}

print_result = client.print.documents_by_id(payload)

# Raw base64 string is preserved as-is
base64_pdf = print_result.reports.first.content
puts base64_pdf[0..30]

To decode outside the wrapper:

require "base64"

binary_pdf = Base64.decode64(base64_pdf)
File.binwrite("label.pdf", binary_pdf)
