Mailgun-Ruby

Build Status Gem Version

This is the Mailgun Ruby Library. This library contains methods for easily interacting with the Mailgun API. Below are examples to get you started. For additional examples, please see our official documentation at https://documentation.mailgun.com

Installation

Via RubyGems

ruby gem install mailgun-ruby

Gemfile:

ruby gem 'mailgun-ruby', '~>1.1.6'

Usage

Here’s how to send a message using the library:

```ruby require ‘mailgun’

First, instantiate the Mailgun Client with your API key

mg_client = Mailgun::Client.new ‘your-api-key’

Define your message parameters

message_params = { from: ‘[email protected]_domain.com’, to: ‘[email protected]’, subject: ‘The Ruby SDK is awesome!’, text: ‘It is really easy to send a message!’ }

Send your message through the client

mg_client.send_message ‘sending_domain.com’, message_params ```

Or obtain the last couple log items:

```ruby # First, instantiate the Mailgun Client with your API key mg_client = Mailgun::Client.new ‘your-secret-api-key’

Define the domain you wish to query

domain = ‘example.com’

Issue the get request

result = mg_client.get(“#domain/events”, => ‘delivered’) ```

Rails

The library can be initialized with a Rails initializer containing similar: ruby Mailgun.configure do |config| config.api_key = 'your-secret-api-key' end Or have the initializer read your environment setting if you perfer.

To use as the ActionMailer delivery method, add this to your config/environments/whatever.rb and replace api-myapikey and mydomain.com with your secret API key and domain, respectively: ruby config.action_mailer.delivery_method = :mailgun config.action_mailer.mailgun_settings = { api_key: 'api-myapikey', domain: 'mydomain.com', }

To get the Mailgun message_id after ActionMailer has successfully delivered the email:

ruby mailer = UserNotifier.welcome_email(current_user) mailer_response = mailer.deliver_now mailgun_message_id = mailer_response.message_id

Response

The results are returned in a Response class:

```ruby result = mg_client.get(“#domain/events”, => ‘delivered’)

To Ruby standard Hash.

result.to_h

To YAML.

result.to_yaml

Or raw JSON

result.body ```

Here’s an example, breaking out the response:

```ruby mg_client = Mailgun::Client.new(“your-api-key”)

message_params = { from: ‘[email protected]’, to: ‘[email protected]’, subject: ‘The Ruby SDK is awesome!’, text: ‘It is really easy to send a message!’ }

result = mg_client.send_message(‘example.com’, message_params).to_h!

message_id = result[‘id’] message = result[‘message’] ```

Debugging

Debugging the Ruby Library can be really helpful when things aren’t working quite right. To debug the library, here are some suggestions:

Set the endpoint to Mailgun’s Postbin. A Postbin is a web service that allows you to post data, which is then displayed through a browser. This allows you to quickly determine what is actually being transmitted to Mailgun’s API.

Step 1 - Create a new Postbin. Go to http://bin.mailgun.net. The Postbin will generate a special URL. Save that URL.

Step 2 - Instantiate the Mailgun client using Postbin.

Tip: The bin id will be the URL part after bin.mailgun.net. It will be random generated letters and numbers. For example, the bin id in this URL, http://bin.mailgun.net/aecf68de, is “aecf68de”.

```ruby # First, instantiate the Mailgun Client with your API key mg_client = Mailgun::Client.new(“your-api-key”, “bin.mailgun.net”, “aecf68de”, ssl = false)

Define your message parameters

message_params = { from: ‘[email protected]_domain.com’, to: ‘[email protected]’, subject: ‘The Ruby SDK is awesome!’, text: ‘It is really easy to send a message!’ }

Send your message through the client

mg_client.send_message(“sending_domain.com”, message_params) ```

For usage examples on each API endpoint, head over to our official documentation pages. Or the Snippets file.

This SDK includes the following components: - Messages - Message Builder - Batch Message - Opt-In Handler - Domains - Webhooks - Events - Suppressions

Message Builder allows you to quickly create the array of parameters, required to send a message, by calling a methods for each parameter. Batch Message is an extension of Message Builder, and allows you to easily send a batch message job within a few seconds. The complexity of batch messaging is eliminated!

Testing mail deliveries

```ruby # First, instantiate the Mailgun Client with your API key mg_client = Mailgun::Client.new ‘your-api-key’

Put the client in test mode

mg_client.enable_test_mode!

Define your message parameters

message_params = { from: ‘[email protected]_domain.com’, to: ‘[email protected]’, subject: ‘The Ruby SDK is awesome!’, text: ‘It is really easy to send a message!’ }

Send your message through the client

# Note: This will not actually hit the API, and will return a generic OK response. mg_client.send_message(‘sending_domain.com’, message_params)

You can now access a copy of message_params

Mailgun::Client.deliveries.first[:from] # => ‘[email protected]_domain.com’ ```

Testing

There are unit tests and integration tests. Unit tests do not require Mailgun account keys. Integration tests do. By default: bundle exec rake spec will run just unit tests. To run integration tests: bundle exec rake spec:integration will run just integration tests. bundle exec rake spec:all will run all both types.

Integrations tests will run against VCR cassettes if they exist. If you’d like to run tests against your mailgun account, remove the cassettes.

To set up Mailgun key information. See the example file: .ruby-env.yml.example. Rename this file to .ruby-env.yml and replace the items between the <> (including the <>) with the private and public keys, and sandbox domain. Alternatively use a different domain registered in Mailgun if you have one you want to test against.

The MAILGUN_* variables in .ruby-env.yml(.example) can also be set as environment variables, if you’d like to do that instead.
