TMS Client

This is a reference Ruby client to interact with the GovDelivery TMS REST API.

Installation

Using Bundler

gem 'govdelivery-tms'

Standalone

$ gem install govdelivery-tms

Connecting

Loading an instance of GovDelivery::TMS::Client will automatically connect to the API to query the available resources for your account.

# default api root endpoint is https://tms.govdelivery.com
client = GovDelivery::TMS::Client.new('auth_token', :api_root => 'https://stage-tms.govdelivery.com')

Messages

Loading messages

Sms and Email messages can be retrieved with the get collection method. Messages are paged in groups of 50. To retrieve another page, used the next method. This method will not be defined if another page is not available.

client.sms_messages.get        # get the first page of sms messages
client.sms_messages.next.get   # get the next page of sms messages

Optional parameters

When loading messages, the following parameters can be passed with requests to change the sort order and number of results returned:

page_size: Must be an integer between 1 and 100

client.sms_messages.get({page_size: 2})                            # get the first two sms messages

sort_by: Field by which to sort results. Default: created_at.

client.sms_messages.get({sort_by: 'created_at'})                  # get the first page of sms messages, sorted by created_at

sort_order: Order by which to sort results. Must be ASC or DESC. Default: DESC.

client.sms_messages.get({sort_order: 'ASC'})                      # get the first page of sms messages, sorted by created_at DESC
client.sms_messages.get({sort_by: 'body', sort_order: 'ASC'})     # get the first page of sms messages, sorted by body ASC

Sending an SMS Message

message = client.sms_messages.build(:body=>'Test Message!')
message.recipients.build(:phone=>'5551112222')
message.recipients.build(:phone=>'5551112223')
message.recipients.build # invalid - no phone
message.post             # true
message.recipients.collection.detect{|r| r.errors } # {"phone"=>["is not a number"]}
# save succeeded, but we have one bad recipient
message.href             # "/messages/sms/87"
message.get              # <GovDelivery::TMS::SmsMessage href=/messages/sms/87 attributes={...}>

Retrieving Inbound SMS Messages

client.inbound_sms_messages.get                             # <GovDelivery::TMS::InboundSmsMessages href=/inbound/sms attributes={...}>
inbound_sms = client.inbound_sms_messages.collection.first  # <GovDelivery::TMS::InboundSmsMessage href=/inbound/sms/10041 attributes={...}>
inbound_sms.to                                              # "+15559999999"
inbound_sms.from                                            # "+15005550006"
inbound_sms.attributes                                      # {:from=>"+15005550006", :to=>"+15559999999", :body=>"test", :command_status=>"success", :keyword_response=>"kwidjebo", :created_at=>"2014-11-05T17:15:01Z"}

Sending an Email Message

message = client.email_messages.build(:body=>'<p><a href="http://example.com">Visit here</a></p>',
                                      :subject => 'Hey')
message.recipients.build(:email=>'example1@example.com')
message.recipients.build(:email=>'')
message.post             # true
message.recipients.collection.detect{|r| r.errors } # {"email"=>["can't be blank"]}
# save succeeded, but we have one bad recipient
message.href             # "/messages/email/87"
message.get              # <GovDelivery::TMS::EmailMessage href=/messages/email/88 attributes={...}>

Sending an Email with Macros

message = client.email_messages.build(:subject=>'Hello!',
                                      :body=>'<p>Hi <span style="color:red;">[[name]]</span>!</p>',
                                      :macros=>{"name"=>"there"})
message.recipients.build(:email=>'jim@example.com', :macros=>{"name"=>"Jim"})
message.recipients.build(:email=>'amy@example.com', :macros=>{"name"=>"Amy"})
message.recipients.build(:email=>'bill@example.com')
message.post

From Addresses

From Addresses are read only resources that define which email addresses you can send an email from and have replies and bounces sent to. From Addresses also have an associated default display name. If you wish to send a message from an address that is not your account's default, you will need to specify a From Address on your Message.

To add or edit From Addresses, you will need to contact your CSC.

# Fetch the from_addresses on your account
client.from_addresses.get

# Get the first from address on your account
from_address = client.from_addresses.collection.first

# Lets see what the emails and display name are
puts from_address.from_email
puts from_address.reply_to_email
puts from_address.bound_email
puts from_address.from_name

# Is this from address the account's default?
puts from_address.is_default

# New messages default to using the default from_address of your account
message = client.email_messages.build(:body=>'<p><a href="http://example.com">Visit here</a></p>',
                                      :subject => 'Hey')

# Specifiy a different from_address using the links hash
message.links[:from_address] = from_address.id

# If you want, you can override the form_name on a message
message.from_name = 'Better Name'
message.post

Creating an Email Template

template = client.email_templates.build(uuid: 'a-new-template',
                                        subject: 'A templated subject',
                                        body: 'Hi [[name]], this body is from a template.',
                                        macros: {"name"=>"person"})
template.post

Updating an Email Template

Note: uuid cannot be updated.

template = client.email_templates.build(:href => 'template/email/a-new-template')
template.get
template.body = 'Hi [[name]], this body is from a new template.'
template.put

Sending an Email using a Template

Assuming you created template above:

message = client.email_messages.build
message.links[:email_template] = template.uuid
message.recipients.build(:email=>'jim@example.com', :macros=>{"name"=>"Jim"})
message.recipients.build(:email=>'amy@example.com', :macros=>{"name"=>"Amy"})
message.recipients.build(:email=>'bill@example.com')
message.post

Creating an SMS Template

template = client.sms_templates.build(uuid: 'a_new-template',
                                      body: 'Hi, [[name]] this is a tempalte.')
template.post

Updating an SMS Template

Note: uuid cannot be updated.

template = client.sms_templates.build(href: 'template/sms/a_new-template')
template.get
template.body = 'Hi, [[name]] this is a new tempalte.'
template.put

Sending an SMS Message using a Template

Assuming you've created template above:

message = client.email_messages.build
message.links[:sms_template] = template.uuid
message.recipients.build(:phone=>'5551112222')
message.recipients.build(:phone=>'5551112223')
message.post

Webhooks

POST to a URL when a recipient is blacklisted (i.e. to remove from your list)

webhook = client.webhooks.build(:url=>'http://your.url', :event_type=>'blacklisted')
webhook.post # true

POSTs will include in the body the following attributes:

attribute	description
message_type	'sms' or 'email'
status:	message state
recipient_url	recipient URL
messsage_url	message URL
error_message	(failures only)
completed_at	(sent or failed recipients only)

Metrics

Viewing recipients that clicked on a link in an email

email_message.get
email_message.clicked.get
email_message.clicked.collection # => [<#EmailRecipient>,...]

Viewing recipients that opened an email

email_message.get
email_message.opened.get
email_message.opened.collection # => [<#EmailRecipient>,...]

Viewing a list of statistics for a recipient

email_recipient.clicks.get.collection #=> [<#EmailRecipientClick>,...]

email_recipient.opens.get.collection #=> [<#EmailRecipientOpen>,...]

Reports

Message recipient counts

Recipient counts are aggregated across all messages and grouped by message status.

start and end are required datetime parameters. They must be truncated to the hour and be in ISO 8601 format (YYYY-MM-DDTHH:MM:SSZ).

End dates are exclusive and all results are based on utc time.

Email

stats = client.reports_messages_email_statistics.get({start: '2017-06-01T10:00:00Z', end: '2017:06:30T18:00:00Z'})     # get email recipient counts for messages sent between 6/1/17 and 6/30/17
stats.recipients

SMS

stats = client.reports_messages_sms_statistics.get({start: '2017-06-01T10:00:00Z', end: '2017:06:30T18:00:00Z'})      # get sms recipient counts for messages sent between 6/1/17 and 6/30/17
stats.recipients

Configuring 2-way SMS

Listing Command Types

Command Types are the available commands that can be used to respond to an incoming SMS message.

command_types = client.command_types.get
command_types.collection.each do |at|
  puts at.name          # "forward"
  puts at.string_fields # ["url", ...]
  puts at.array_fields  # ["foo", ...]
end

Managing Keywords

Keywords are chunks of text that are used to match an incoming SMS message.

# CRUD
keyword = client.keywords.build(:name => "BUSRIDE", :response_text => "Visit example.com/rides for more info")
keyword.post                # true
keyword.name                # 'busride'
keyword.name = "TRAINRIDE"
keyword.put                 # true
keyword.name                # 'trainride'
keyword.delete              # true

# list
keywords = client.keywords.get
keywords.collection.each do |k|
  puts k.name, k.response_text
end

Managing Commands

Commands have a command type and one or more keywords. The example below configures the system to respond to an incoming SMS message containing the string "RIDE" (or "ride") by forwarding an http POST to http://example.com/new_url. The POST body variables are documented in GovDelivery's TMS REST API documentation.

# CRUD
keyword = client.keywords.build(:name => "RIDE")
keyword.post
command = keyword.commands.build(
            :name => "Forward to somewhere else",
            :params => {:url => "http://example.com", :http_method => "get"},
            :command_type => :forward)
command.post
command.params = {:url => "http://example.com/new_url", :http_method => "post"}
command.put
command.delete

# list
commands = keyword.commands.get
commands.collection.each do |c|
  puts c.inspect
end

Viewing Command Actions

Each time a given command is executed, a command action is created.

Note The actions relationship does not exist on commands that have 0 command actions. Because of this, an attempt to access the command_actions attribute of a command that has 0 command actions will result in a NoMethodError.

# Using the command from above
begin
  command.get
  command_actions = command.command_actions
  command_actions.get
  command_action = command_actions.collection.first
  command_action.inbound_sms_message		# InboundSmsMessage object that initiated this command execution
  command_action.response_body			# String returned by the forwarded to URL
  command_action.status				# HTTP Status returned by the forwarded to URL
  command_action.content_type			# Content-Type header returned by the forwarded to URL
rescue NoMethodError => e
  # No command actions to view
end

Logging

Any instance of a Logger-like class can be passed in to the client; incoming and outgoing request information will then be logged to that instance.

The example below configures GovDelivery::TMS::Client to log to STDOUT:

logger = Logger.new(STDOUT)
client = GovDelivery::TMS::Client.new('auth_token', :logger => logger)

ActionMailer integration

You can use TMS from the mail gem or ActionMailer as a delivery method.

Gemfile

gem 'govdelivery-tms', :require=>'govdelivery/tms/mail/delivery_method'

config/environment.rb

config.action_mailer.delivery_method = :govdelivery_tms
config.action_mailer.govdelivery_tms_settings = {
    :auth_token=>'auth_token',
    :api_root=>'https://tms.govdelivery.com'
    }

Generating Documentation

This project uses yard to generate documentation. To generate API documentation yourself, use the following series of commands from the project root:

# install development gems
bundle install
# generate documentation
bundle exec rake yard

The generated documentation will be placed in the doc folder.

Running Tests

bundle install
bundle exec rake
