Delighted API Ruby Client

Official Ruby client for the Delighted API.


Add gem 'delighted' to your application's Gemfile, and then run bundle to install.


To get started, you need to configure the client with your secret API key. If you're using Rails, you should add the following to new initializer file in config/initializers/delighted.rb.

require 'delighted'
Delighted.api_key = 'YOUR_API_KEY'

For further options, read the advanced configuration section.

Note: Your API key is secret, and you should treat it like a password. You can find your API key in your Delighted account, under Settings > API.


Adding/updating people and scheduling surveys:

# Add a new person, and schedule a survey immediately
person1 = Delighted::Person.create(:email => "")

# Add a new person, and schedule a survey after 1 minute (60 seconds)
person2 = Delighted::Person.create(:email => "",
  :delay => 60)

# Add a new person, but do not schedule a survey
person3 = Delighted::Person.create(:email => "",
  :send => false)

# Add a new person with full set of attributes, including a custom question
# product name, and schedule a survey with a 30 second delay
person4 = Delighted::Person.create(:email => "",
  :name => "Joe Bloggs", :properties => { :customer_id => 123, :country => "USA",
  :question_product_name => "The London Trench" }, :delay => 30)

# Update an existing person (identified by email), adding a name, without
# scheduling a survey
updated_person1 = Delighted::Person.create(:email => "",
  :name => "James Scott", :send => false)

Listing all people:

# List all people, auto pagination
# Note: Make sure to handle the possible rate limits error
people = Delighted::Person.list
  people.auto_paging_each do |person|
    # Do something with person
rescue Delighted::RateLimitError => e
  # Indicates how long to wait before making this request again

# For convenience, this method can use a sleep to automatically handle rate limits
people.auto_paging_each({ auto_handle_rate_limits: true }) do |person|
  # Do something with person

Unsubscribing people:

# Unsubscribe an existing person
Delighted::Unsubscribe.create(:person_email => "")

Listing people who have unsubscribed (auto pagination not supported):

# List all people who have unsubscribed, 20 per page, first 2 pages
survey_responses_page1 = Delighted::Unsubscribe.all
survey_responses_page2 = Delighted::Unsubscribe.all(:page => 2)

Listing people whose emails have bounced (auto pagination not supported):

# List all people whose emails have bounced, 20 per page, first 2 pages
survey_responses_page1 = Delighted::Bounce.all
survey_responses_page2 = Delighted::Bounce.all(:page => 2)

Deleting a person and all of the data associated with them:

# Delete by person id
Delighted::Person.delete(:id => 42)
# Delete by email address
Delighted::Person.delete(:email => "")
# Delete by phone number (must be E.164 format)
Delighted::Person.delete(:phone_number => "+14155551212")

Deleting pending survey requests

# Delete all pending (scheduled but unsent) survey requests for a person, by email.
Delighted::SurveyRequest.delete_pending(:person_email => "")

Adding survey responses:

# Add a survey response, score only
survey_response1 = Delighted::SurveyResponse.create(:person =>,
  :score => 10)

# Add *another* survey response (for the same person), score and comment
survey_response2 = Delighted::SurveyResponse.create(:person =>,
  :score => 5, :comment => "Really nice.")

Retrieving a survey response:

# Retrieve an existing survey response
survey_response3 = Delighted::SurveyResponse.retrieve('123')

Updating survey responses:

# Update a survey response score
survey_response4 = Delighted::SurveyResponse.retrieve('234')
survey_response4.score = 10 #=> #<Delighted::SurveyResponse:...>

# Update (or add) survey response properties
survey_response4.person_properties = { :segment => "Online" } #=> #<Delighted::SurveyResponse:...>

# Update person who recorded the survey response
survey_response4.person = '321' #=> #<Delighted::SurveyResponse:...>

Listing survey responses:

# List all survey responses, 20 per page, first 2 pages
survey_responses_page1 = Delighted::SurveyResponse.all
survey_responses_page2 = Delighted::SurveyResponse.all(:page => 2)

# List all survey responses, 20 per page, expanding person object
survey_responses_page1_expanded = Delighted::SurveyResponse.all(:expand => ['person'])
survey_responses_page1_expanded[0].person #=> #<Delighted::Person:...>

# List all survey responses, 20 per page, for a specific trend (ID: 123)
survey_responses_page1_trend = Delighted::SurveyResponse.all(:trend => "123")

# List all survey responses, 20 per page, in reverse chronological order (newest first)
survey_responses_page1_desc = Delighted::SurveyResponse.all(:order => 'desc')

# List all survey responses, 100 per page, page 5, with a time range
filtered_survey_responses = Delighted::SurveyResponse.all(:page => 5,
  :per_page => 100, :since => Time.utc(2013, 10, 01),
  :until => Time.utc(2013, 11, 01))

Retrieving metrics:

# Get current metrics, 30-day simple moving average, from most recent response
metrics = Delighted::Metrics.retrieve

# Get current metrics, 30-day simple moving average, from most recent response,
# for a specific trend (ID: 123)
metrics = Delighted::Metrics.retrieve(:trend => "123")

# Get metrics, for given range
metrics = Delighted::Metrics.retrieve(:since => Time.utc(2013, 10, 01),
  :until => Time.utc(2013, 11, 01))

Rate limits

If a request is rate limited, a Delighted::RateLimitedError exception is raised. You can rescue that exception to implement exponential backoff or retry strategies. The exception provides a #retry_after method to tell you how many seconds you should wait before retrying. For example:

  metrics = Delighted::Metrics.retrieve
rescue Delighted::RateLimitedError => e
  retry_after_seconds = e.retry_after
  # wait for retry_after_seconds before retrying
  # add your retry strategy here ...

Advanced configuration & testing

The following options are configurable for the client:

Delighted.api_base_url # default: ''
Delighted.http_adapter # default:

By default, a shared instance of Delighted::Client is created lazily in Delighted.shared_client. If you want to create your own client, perhaps for test or if you have multiple API keys, you can:

# Create a custom client instance, and pass as last argument to resource actions
client = => 'API_KEY',
  :api_base_url => '',
  :http_adapter =>
metrics_from_custom_client = Delighted::Metrics.retrieve({}, client)

# Or, you can set Delighted.shared_client yourself
Delighted.shared_client = => 'API_KEY',
  :api_base_url => '',
  :http_adapter =>
metrics_from_custom_shared_client = Delighted::Metrics.retrieve
