Gibbon is an API wrapper for MailChimp's Primary and Export APIs.
##Important Notes About Version 0.5.0+
Gibbon now targets MailChimp API 2.0, which is substantially different from API 1.3. Please use Gibbon 0.4.6 if you need to use API 1.3.
- Supports MailChimp API 2.0 and Export API 1.0
- Errors are raised by default since 0.4.x
- Timeouts can be specified per request during initialization
- Ruby 1.9.x+ for now. A future version may be Ruby 2.0 only to take advantage of lazy iteration when using the Export API.
##Installation
$ gem install gibbon
##Requirements
A MailChimp account and API key. You can see your API keys here.
##Usage
There are a few ways to use Gibbon:
You can create an instance of the API wrapper:
gb = Gibbon::API.new("your_api_key")
You can set api_key, timeout and throws_exceptions globally:
Gibbon::API.api_key = "your_api_key"
Gibbon::API.timeout = 15
Gibbon::API.throws_exceptions = false
similarly
Gibbon::Export.api_key = "your_api_key"
Gibbon::Export.timeout = 15
Gibbon::Export.throws_exceptions = false
For example, you could set the values above in an initializer file in your Rails app (e.g. your_app/config/initializers/gibbon.rb).
Assuming you've set an api_key on Gibbon, you can conveniently make API calls on the class itself:
Gibbon::API.lists.list
You can also set the environment variable MAILCHIMP_API_KEY and Gibbon will use it when you create an instance:
gb = Gibbon::API.new
Note: In an effort to simplify Gibbon, the environment variable 'MC_API_KEY' is no longer available as of version 0.4.0. Please use 'MAILCHIMP_API_KEY' instead.
Fetching data is as simple as calling API methods directly on the wrapper object with a given category (e.g. campaigns.list). The API calls may be made with either camelcase or underscore separated formatting as you see in the "More Advanced Examples" section below.
Check the API documentation for details.
For example, to fetch your first 100 campaigns (page 0):
campaigns = gb.campaigns.list({:start => 0, :limit => 100})
Similarly, to fetch your first 100 lists:
lists = gb.lists.list({:start => 0, :limit=> 100})
Or, to fetch a list by name:
list = gb.lists.list({:filters => {:list_name => list_name}})
Getting batch member information for subscribers looks like this:
info = gb.lists.member_info({:id => list_id, :email_address => email_array})
List subscribers for a list:
gb.lists.members({:id => list_id})
or
List unsubscribed members for a list
gb.lists.members({:id => list_id, :status => "unsubscribed"})
Subscribe a member to a list:
gb.lists.subscribe({:id => list_id, :email => {:email => 'email_address'}, :merge_vars => {:FNAME => 'First Name', :LNAME => 'Last Name'}, :double_optin => false})
Note: This will send a welcome email to the new subscriber
or
Batch subscribe members to a list:
gb.lists.batch_subscribe(:id => list_id, :batch => [{:EMAIL => "email1", :FNAME => "FirstName1", :LNAME => "LastName1"},{:EMAIL => "email2", :FNAME => "FirstName2", :LNAME => "LastName2"}])
Note: This will send welcome emails to the new subscribers
Fetch recipients who opened particular campaign:
email_stats = gb.reports.opened({:cid => campaign_id})
or
Create a campaign:
gb.campaigns.create({type: "regular", options: {list_id: list_id, subject: "Gibbon is cool", from_email: "[email protected]", from_name: "Darth Vader", generate_text: true}, content: {html: "<html><head></head><body><h1>Foo</h1><p>Bar</p></body></html>"}})
Overriding Gibbon's API endpoint (i.e. if using an access token from OAuth and have the api_endpoint from the metadata):
Gibbon::API.api_endpoint = "https://us1.api.mailchimp.com"
Gibbon::API.api_key = your_access_token_or_api_key
Gibbon defaults to a 30 second timeout. You can optionally set your own timeout (in seconds) like so:
gb = Gibbon::API.new("your_api_key", {:timeout => 5})
or
gb.timeout = 5
By default Gibbon will attempt to raise errors returned by the API automatically.
If you set the throws_exceptions boolean attribute to false, for a given instance,
then Gibbon will not raise exceptions. This allows you to handle errors manually. The
APIs will return a Hash with two keys "errors", a string containing some textual
information about the error, and "code", the numeric code of the error.
If you rescue Gibbon::MailChimpError, you are provided with the error message itself as well as
a code attribute that you can map onto the API's error list. The API docs list possible errors
at the bottom of each page.
Note: In an effort to make Gibbon easier to use, errors are raised automatically as of version 0.4.0.
In addition to the primary API, you can make calls to the Export API using an instance of GibbonExport. Given an existing instance of Gibbon, you can request a new GibbonExporter object:
g = Gibbon::API.new("your_api_key")
gibbon_export = g.get_exporter
or you can construct a new object directly:
gibbon_export = Gibbon::Export.new("your_api_key")
Making calls to Export API endpoints is similar to making standard API calls but the return value is an Enumerator which loops over the lines returned from the Export API. This is because the data returned from the Export API is a stream of JSON objects rather than a single JSON array.
For example, dumping list members via the "list" method works like this:
gibbon_export.list({id => list_id})
##Thanks
Thanks to everyone who's contributed to Gibbon's development. Major props to Jesse at MailChimp for adding nice stuff in API 2.0 that makes it easier to develop against.
