Ruby Wrapper for OCA e-Pak API

For command line usage:

$ gem install oca-epak

If you intend to use it within an application, add gem "oca-epak" to your Gemfile.

First, initialize an Oca client:

oca = Oca.new("your-email@example.com", "your-password")

To check whether your credentials are valid or not, run #check_credentials

oca.check_credentials
=> true

Once you have an operation code from Oca, you can check if it's already active and available for use by running #check_operativa:

oca.check_operativa("30-99999999-7", "77790")
=> true

NOTE: Keep in mind that you cannot register/create an operation code via Oca's API, you have to get in touch with someone from Oca and they take care of the registration.

After you have your operation code active for a given delivery type, you can begin calculating shipping rates and delivery estimates:

opts = { wt: "50", vol: "0.027", origin: "1646", destination: "2000", qty: "1", 
  cuit: "30-99999999-7", op: "77790" }

oca.get_shipping_rates(opts)
=> {:tarifador=>"15",
    :precio=>"328.9000",
    :id_tiposervicio=>"2",
    :ambito=>"Regional",
    :plazo_entrega=>"3",
    :adicional=>"0.0000",
    :total=>"328.9000",
    :xml=>"<row Tarifador=\"15\" Precio=\"328.9000\"/>",
    :"@diffgr:id"=>"Table1",
    :"@msdata:row_order"=>"0"}
