gibbon

Gibbon is an API wrapper for MailChimp's API.

Build Status Dependency Status

Important Notes

Gibbon now targets MailChimp API 3.0, which is substantially different from the previous API. Please use Gibbon 1.1.x if you need to use API 2.0.

Please read MailChimp's Getting Started Guide.

Installation

$ gem install gibbon

Requirements

A MailChimp account and API key. You can see your API keys here.

Usage

First, create an instance Gibbon::Request:

gibbon = Gibbon::Request.new(api_key: "your_api_key")

You can set an individual request's timeout like this:

gibbon.timeout = 10

Now you can make requests using the resources defined in MailChimp's docs. Resource IDs are specified inline and a CRUD (create, retrieve, update, upsert, or delete) verb initiates the request. upsert lets you update a record, if it exists, or insert it otherwise where supported by MailChimp's API.

Please note that upsert requires Gibbon version 2.1.0 or newer!

You can specify headers, params, and body when calling a CRUD method. For example:

gibbon.lists.retrieve(headers: {"SomeHeader": "SomeHeaderValue"}, params: {"query_param": "query_param_value"})

Of course, body is only supported on create, update, and upsert calls. Those map to HTTP POST, PATCH, and PUT verbs respectively.

You can set api_key and timeout globally:

Gibbon::Request.api_key = "your_api_key"
Gibbon::Request.timeout = 15

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::Request.lists.retrieve

You can also set the environment variable MAILCHIMP_API_KEY and Gibbon will use it when you create an instance:

gibbon = Gibbon::Request.new

MailChimp's resource documentation is a list of available resources. Substitute an underscore if a resource name contains a hyphen.

Examples

Lists

Fetch all lists:

gibbon.lists.retrieve

Retrieving a specific list looks like:

gibbon.lists(list_id).retrieve

Retrieving a specific list's members looks like:

gibbon.lists(list_id).members.retrieve

Subscribers

Get all subscribers for a list:

gibbon.lists(list_id).members.retrieve

By default the Mailchimp API returns 10 results. To set the count to 50:

gibbon.lists(list_id).members.retrieve(params: {"count": "50"})

And to retrieve the next 50 members:

gibbon.lists(list_id).members.retrieve(params: {"count": "50", "offset: "50"})

Subscribe a member to a list:

gibbon.lists(list_id).members.create(body: {email_address: "foo@bar.com", status: "subscribed", merge_fields: {FNAME: "First Name", LNAME: "Last Name"}})

If you want to upsert instead, you would do the following:

gibbon.lists(list_id).members(lower_case_md5_hashed_email_address).upsert(body: {email_address: "foo@bar.com", status: "subscribed", merge_fields: {FNAME: "First Name", LNAME: "Last Name"}})

You can also unsubscribe a member from a list:

gibbon.lists(list_id).members(lower_case_md5_hashed_email_address).update(body: { status: "unsubscribed" })

Fields

Only retrieve ids and names for fetched lists:

gibbon.lists.retrieve(params: {"fields": "lists.id,lists.name"})

Only retrieve emails for fetched lists:

gibbon.lists(list_id).members.retrieve(params: {"fields": "members.email_address"})

Campaigns

Get all campaigns:

campaigns = gibbon.campaigns.retrieve

Fetch the number of opens for a campaign

email_stats = gibbon.reports(campaign_id).retrieve["opens"]

Create a new campaign:

recipients = {
  list_id: list_id,
  segment_opts: {
    saved_segment_id: segment_id
  }
}
settings = {
  subject_line: "Subject Line",
  title: "Name of Campaign",
  from_name: "From Name",
  reply_to: "my@email.com"
}

body = {
  type: "regular",
  recipients: recipients,
  settings: settings
}

begin
  gibbon.campaigns.create(body: body)
rescue Gibbon::MailChimpError => e
  puts "Houston, we have a problem: #{e.message} - #{e.raw_body}"
end

Add content to a campaign:

(Please note that Mailchimp does not currently support dynamic replacement of mc:edit areas in their drag-and-drop templates using their API. Custom templates can be used instead.)

body = {
  template: {
    id: template_id,
    sections: {
      "name-of-mc-edit-area": "Content here"
    }
  }
}

gibbon.campaigns(campaign_id).content.upsert(body: body)

Send a campaign:

gibbon.campaigns(campaign_id).actions.send.create

Interests

Interests are a little more complicated than other parts of the API, so here's an example of how you would set interests during at subscription time or update them later. The ID of the interests you want to opt in or out of must be known ahead of time so an example of how to find interest IDs is also included.

Subscribing a member to a list with specific interests up front:

g.lists(list_id).members.create(body: {email_address: user_email_address, status: "subscribed", interests: {some_interest_id: true, another_interest_id: true}})

Updating a list member's interests:

gibbon.lists(list_id).members(member_id).update(body: {interests: {some_interest_id: true, another_interest_id: false}})

So how do we get the interest IDs? When you query the API for a specific list member's information:

g.lists(list_id).members(member_id).retrieve

The response looks someting like this (unrelated things removed):

{"id"=>"...", "email_address"=>"...", ..., "interests"=>{"3def637141"=>true, "f7cc4ee841"=>false, "fcdc951b9f"=>false, "3daf3cf27d"=>true, "293a3703ed"=>false, "72370e0d1f"=>false, "d434d21a1c"=>false, "bdb1ff199f"=>false, "a54e78f203"=>false, "c4527fd018"=>false} ...}

The API returns a map of interest ID to boolean value. Now we to get interest details so we know what these interest IDs map to. Looking at this doc page, we need to do this:

g.lists(list_id).interest_categories.retrieve

To get a list of interest categories. That gives us something like:

{"list_id"=>"...", "categories"=>[{"list_id"=>"...", "id"=>"0ace7aa498", "title"=>"Food Preferences", ...}] ...}

In this case, we're interested in the ID of the "Food Preferences" interest, which is 0ace7aa498. Now we can fetch the details for this interest group:

g.lists(list_id).interest_categories("0ace7aa498").interests.retrieve

That response gives the interest data, including the ID for the interests themselves, which we can use to update a list member's interests or set them when we call the API to subscribe her or him to a list.

Error handling

Gibbon raises an error when the API returns an error.

Gibbon::MailChimpError has the following attributes: title, detail, body, raw_body, status_code. Some or all of these may not be available depending on the nature of the error.

Other

Overriding Gibbon's API endpoint (i.e. if using an access token from OAuth and have the api_endpoint from the metadata):

Gibbon::Request.api_endpoint = "https://us1.api.mailchimp.com"
Gibbon::Request.api_key = your_access_token_or_api_key

You can set an optional proxy url like this (or with an environment variable MAILCHIMP_PROXY):

gibbon.proxy = 'http://your_proxy.com:80'

You can set a different Faraday adapter during initialization:

gibbon = Gibbon::Request.new(api_key: "your_api_key", faraday_adapter: :net_http)

Migrating from Gibbon 1.x

Gibbon 2.x has different syntax from version 1.x. This is because Gibbon maps to MailChimp's API and because version 3 of the API is quite different from version 2. First, the name of the primary class has changed from API to Request. And the way you pass an API key during initialization is different. A few examples below.

Initialization

Gibbon 1.x:

gibbon = Gibbon::API.new("your_api_key")

Gibbon 2.x:

gibbon = Gibbon::Request.new(api_key: "your_api_key")

MailChimp API 3 is a RESTful API, so Gibbon's syntax now requires a trailing call to a verb, as described above.

Fetching Lists

Gibbon 1.x:

gibbon.lists.list

Gibbon 2.x:

gibbon.lists.retrieve

Fetching List Members

Gibbon 1.x:

gibbon.lists.members({:id => list_id})

Gibbon 2.x:

gibbon.lists(list_id).members.retrieve

Subscribing a Member to a List

Gibbon 1.x:

gibbon.lists.subscribe({:id => list_id, :email => {:email => "foo@bar.com"}, :merge_vars => {:FNAME => "Bob", :LNAME => "Smith"}})

Gibbon 2.x:

gibbon.lists(list_id).members.create(body: {email_address: "foo@bar.com", status: "subscribed", merge_fields: {FNAME: "Bob", LNAME: "Smith"}})
