A client API to the MailGun Email RESTful API.

You can sign up for a free account at:

And the latest API documentation is available at:

https://documentation.mailgun.com/en/latest/

To access direct calls to the service, you will want to use the MailgunEx.Api module. When making requests, you can provide several opts, all of which can be defaulted using Mix.Config.

Here is an example of how to configure this library

config :mailgun_ex,
  base: "https://api.mailgun.net/v3",
  mode: :live,
  domain: "namedb.org",
  api_key: "key-3ax6xnjp29jd6fds4gc373sgvjxteol0",
  http_opts: %{
    timeout: 5000,
  }

The configs use a library called Deferred Config so that you can use environment variables that will be loaded at runtime, versus compiled into the release.

Here’s an example of how to use the system variables

config :mailgun_ex,
  base: "https://api.mailgun.net/v3",
  mode: {:system, "MAILGUN_MODE", :live, {String, :to_atom}},
  domain: {:system, "MAILGUN_DOMAIN", "defaultname.com"} ,
  api_key: {:system, "MAILGUN_API_KEY"},
  http_opts: %{
    timeout: 5000,
  }

Our default mix test tests will use Bypass as the base service URL so that we will not hit your production MailGun account during testing.

Here is an outline of all the configurations you can set.

• :base - The base URL which defaults to https://api.mailgun.net/v3
• :mode - Defaults to :live, but can be set to :simulate for testing, or :ignore for dev
• :domain - The domain making the request (e.g. namedb.org)
• :api_key - Your mailgun API key, which looks like key-3ax6xnjp29jd6fds4gc373sgvjxteol0
• :http_opts - A passthrough map of options to send to HTTP request, more details below

This client library uses HTTPoison for all HTTP communication, and we will pass through any :http_opts you provide, which we have shown below.

• :timeout - timeout to establish a connection, in milliseconds. Default is 8000
• :recv_timeout - timeout used when receiving a connection. Default is 5000
• :stream_to - a PID to stream the response to
• :async - if given :once, will only stream one message at a time, requires call to stream_next
• :proxy - a proxy to be used for the request; it can be a regular url or a {Host, Port} tuple
• :proxy_auth - proxy authentication {User, Password} tuple
• :ssl - SSL options supported by the ssl erlang module
• :follow_redirect - a boolean that causes redirects to be followed
• :max_redirect - an integer denoting the maximum number of redirects to follow
• :params - an enumerable consisting of two-item tuples that will be appended to the url as query string parameters
