MWSClient

An Elixir client for accessing Amazon's Merchant Web Services

Inspired by ruby https://github.com/hakanensari/peddler gem api and elixir https://github.com/zachgarwood/elixir-amazon-product-advertising-client for signature signing.

Only implemented APIs for what I needed, other API's need to be ported as I go along.

Usage:

Fill out a %MWSClient.Config struct that holds credentials needed for signature creation.

  MWSClient.Products.get_matching_product(["B00KO1C94A"]) |> MWSClient.request(config)

The first part creates an %MWSClient.Operation struct holding basic parts of the API call, e.g map of parameters to send, the path, the method.

The second part the MWSClient.request appends additional parameters from your config struct, creates a signature and makes the API call. The result is a %HTTPoison{} struct.

Pipe that into a parser to facilitate enumerating over csv or xml response body.

  MWSClient.Products.get_matching_product(["B00KO1C94A"]) |> MWSClient.request(config)
   |> MWSClient.Parse.parse

MWSClient.Parser.parse determines the enumerable based on the response header content-type.
