Shippex is an abstraction of commonly used features in shipping with various carriers. It provides a (hopefully) pleasant API to work with carrier-provided web interfaces for fetching rates and printing shipping labels.

As of now, only UPS and USPS are supported. More carrier support will come in the future. Units of measurement are mostly hardcoded to inches and miles.

## Installation

Add `shippex` to your list of dependencies in `mix.exs`:

def deps do
  [{:shippex, "~> 0.11"}]

Ensure `shippex` is started before your application:

def application do
  [applications: [:shippex]]

## Configuration

config :shippex,
  env: :dev,
  distance_unit: :in, # either :in or :cm
  weight_unit: :lbs, # either :lbs or :kg
  currency: :usd, # :usd, :can, :mxn, :eur

shipment =, destination, package)

# Fetch rates to present to the user.
rates = Shippex.fetch_rates(shipment, carriers: :usps)

# Accept one of the services and print the label
{:ok, rate} = Enum.shuffle(rates) |> hd

# Fetch the label. Includes the tracking number and a gif image of the label.
{:ok, transaction} = Shippex.create_transaction(shipment, rate.service)

rate = transaction.rate
label = transaction.label

# Print the price.

# Write the label to disk.
File.write!("#{label.tracking_number}.#{label.format}", Base.decode64!(label.image))
