This is a basic Elixir wrapper for version 3 of the MailChimp API.

Installation

First, add MailChimp lib to your mix.exs dependencies:

def deps do
  [{:mailchimp, "~> 0.0.2"}]
end

and run $ mix deps.get. Now, list the :mailchimp application as your application dependency:

def application do
  [applications: [:mailchimp]]
end

Usage

1. Put your API key in your config.exs file:

config :mailchimp,
  apikey: "your api-us10"

2. Start a new process:

   Mailchimp.start_link

Phoenix and OTP

You can easily utilize Phoenix and OTP to start Mailchimp supervised. Simply add Mailchimp as a worker process to your Application:

# lib/my_app.ex
defmodule MyApp do
  use Application

  def start(_type, _args) do
    # ...
    children = [
      # ...
      worker(Mailchimp, [[name: :mailchimp]])
    ]
    # ...
  end
  # ...
end

Getting Account Details

Mailchimp.get_account_details()

Getting All Lists

Mailchimp.get_all_lists()

Adding a Member to a List

Mailchimp.add_member("list_id", "e-mail")

Example of adding a Member to a List with merge_fields:

def add_to_list(list_id, user) do
  merge_fields = %{
    "FNAME" => user.first_name,
    "LNAME" => user.last_name,
    "COMPANY" => user.organisation,
    "MMERGE4" => %{
      "addr1" => user.address,
      "addr2" => "-",
      "city" => user.city,
      "state" => "-",
      "zip" => to_string(user.postal_code),
      "country" => user.country,
    }
  }

  Mailchimp.add_member(list_id, user.email, merge_fields)
end

Hint: Merge fields of type "address" require ALL fields to be of type "string". Ensure your zip code is a string.
