Elixir client that integrates with Correios API.
- Calculate shipping price and deadline;
- Search an address by postal code.
Add ExCorreios to your list of dependencies in mix.exs:
def deps do
[
{:ex_correios, git: "https://code.locaweb.com.br/locawebcommons/ex-correios"}
]
endAdd the following config to your config.exs file:
config :ex_correios,
address_url: "https://apps.correios.com.br/SigepMasterJPA/AtendeClienteService/AtendeCliente",
calculator_url: "http://ws.correios.com.br/calculador/CalcPrecoPrazo.aspx",
proxy: {"proxyhost.com", "8866"}1 - Build one or more package items
iex> dimensions = %{diameter: 40.0, height: 2.0, length: 16.0, weight: 0.9, width: 11.0}
iex> dimensions2 = %{diameter: 0.0, height: 0.0, length: 0.0, weight: 0.0, width: 0.0}2 - Build a package with an item to calculate shipping
iex> package = ExCorreios.Calculator.Shipping.Package.build(:package_box, [dimensions])
%ExCorreios.Calculator.Shipping.Package{
diameter: 40.0,
format: 1,
height: 2.0,
length: 16.0,
weight: 0.9,
width: 11.0
}2.1 - When the package dimensions is smaller than the min dimensions accepted, we'll use the min dimensions defined by the correios
iex> package = ExCorreios.Calculator.Shipping.Package.build(:package_box, [dimensions2])
%ExCorreios.Calculator.Shipping.Package{
diameter: 0.0,
format: 1,
height: 2.0,
length: 16.0,
weight: 0.0,
width: 11.0
}2.2 - It's possible to pass only the weight to build a package
iex> ExCorreios.Calculator.Shipping.Package.build(:package_box, [%{weight: 0.3}])
%ExCorreios.Calculator.Shipping.Package{
diameter: 0.0,
format: 1,
height: 2.0,
length: 16.0,
weight: 0.3,
width: 11.0
}2.3 - Build a package with one or more items to calculate shipping
iex> package = ExCorreios.Calculator.Shipping.Package.build(:package_box, [dimensions, dimensions2])
%ExCorreios.Calculator.Shipping.Package{
diameter: 40.0,
format: 1,
height: 7.06,
length: 16.0,
weight: 0.9,
width: 11.0
}3 - Calculate shipping based on one or more services
iex> shipping_params = %{
destination: "05724005",
origin: "08720030",
enterprise: "",
password: "",
receiving_alert: false,
declared_value: 0,
manually_entered: false
}
iex> ExCorreios.calculate([:pac], package, shipping_params)
{:ok,
[
%{
deadline: 5,
declared_value: 0.0,
error: nil,
error_code: "0",
error_message: "",
home_delivery: "S",
manually_entered_value: 0.0,
name: "PAC",
notes: "",
receiving_alert_value: 0.0,
response_status: "0",
saturday_delivery: "N",
service_code: "04510",
value: 19.8,
value_without_additionals: 19.8
}
]
}
iex> ExCorreios.calculate([:pac, :sedex], package, shipping_params)
{:ok,
[
%{
deadline: 5,
declared_value: 0.0,
error: nil,
error_code: "0",
error_message: "",
home_delivery: "S",
manually_entered_value: 0.0,
name: "PAC",
notes: "",
receiving_alert_value: 0.0,
response_status: "0",
saturday_delivery: "N",
service_code: "04510",
value: 19.8,
value_without_additionals: 19.8
},
%{
deadline: 2,
declared_value: 0.0,
error: nil,
error_code: "0",
error_message: "",

saturday_delivery: "S",
service_code: "04014",
value: 21.2,
value_without_additionals: 21.2
}
]
}3.1 - It's possible for a service returns an error message while the other returns a success message
iex> ExCorreios.calculate([:pac, :sedex_hoje], package, shipping_params)
{:ok,
[
%{
deadline: 5,
declared_value: 0.0,
error: nil,
error_code: "0",

},
%{
deadline: 0,
declared_value: 0.0,
error: :invalid_destination_postal_code,
error_code: "008",
error_message: "Serviço indisponível para o trecho informado.",
home_delivery: "",
manually_entered_value: 0.0,
name: "SEDEX HOJE",
notes: "",

}
