Detailed technical documentation on using RudderStack’s Ruby SDK to send events to various destinations.
The RudderStack Ruby SDK lets you track your customer event data from your Ruby code and send it to your specified destinations via RudderStack.
Check out the GitHub codebase to get a more hands-on understanding of the SDK.
SDK setup requirements
To set up the RudderStack Ruby SDK, the following prerequisites must be met:
You will need to set up a RudderStack account.
Once signed up, set up a Ruby source in the dashboard. For more information, follow this guide. You should then see a Write Key for this source, as shown below:
You will also need a data plane URL. Follow this section for more information on the data plane URL and where to get it.
Installing the Ruby SDK
To install the RudderStack Ruby SDK, add this line to your application's Gem file:
gem 'rudder_analytics_sync'
You can also install it yourself, as shown:
gem install rudder_analytics_sync
Using the SDK
To use the SDK, create a client instance as shown in the following snippet:
require 'rudder_analytics_sync'
Analytics = RudderAnalyticsSync::Client.new(
write_key: WRITE_KEY, # required
data_plane_url: DATA_PLANE_URL
on_error: proc { |error_code, error_body, exception, response|
# defaults to an empty proc
}
)
You can then use this client to send event requests, as shown:
Analytics.track(
user_id: user.id,
event: 'Created Account'
)
Manually batching events
You can manually batch events with Analytics.batch
as shown:
Analytics.batch do |batch|
batch.context = {...} # shared context for all events
batch.integrations = {...} # shared integrations hash for all events
batch.identify(...)
batch.track(...)
batch.track(...)
...
end
Identify
The identify
call lets you identify a visiting user and capture any related information such as their name, email address, etc.
RudderStack does not store the user state in any of the server-side SDKs. Unlike the client-side SDKs that deal with only a single user at a given time, the server-side SDKs deal with multiple users at the same time. Therefore, for any of the calls supported by the Node.js SDK, you need to specify either userId
or anonymousId
every time.
A sample identify
call is as shown:
Analytics.identify(
user_id: '12345',
traits: { email: "#{ username.email }", friends: 1 },
context: {ip: '10.81.20.10'}
)
The identify
method parameters are as shown:
Field
Type
Presence
Description
anonymousId
String
Optional
Sets the user ID for cases where there is no unique identifier for the user. Either userId
or anonymousId
is required.
userId
String
Optional, if anonymousId
is already set
Unique identifier for a particular user in your database.
context

Optional
A dictionary containing the destinations to be either enabled or disabled.
timestamp
Date
Optional
The timestamp of the message's arrival.
traits
Object
Optional
Dictionary of the traits associated with the user, such as name
or email
.
Track
The track
call lets you record the user actions along with their associated properties. Each user action is called an event.
A sample track
call is shown below:
Analytics.track(
user_id: '12345',
event: 'Item Sold',
properties: { revenue: 9.95, shipping: 'Free' }
)
The track
method parameters are as described below:
user_id

Optional
Sets the user ID for cases where there is no unique identifier for the user. Either userId
or anonymousId
is required.
integrations

Page
The page
call allows you to record the page views on your website along with the other relevant information about the viewed page.
A sample page
call is as shown:
Analytics.page(
user_id: userid,
category: 'Food',
name: 'Pizza',
properties: { url: 'https://dominos.com' }
)
The page
method parameters are as described below:

String
Required
Name of the page being viewed.
properties
Object
Optional
Dictionary of the properties associated with the page being viewed, such as url
and referrer
timestamp
Date
Optional
The timestamp of the message's arrival.
Group
The group
call lets you associate an identified user to a group - either a company, project or a team and record any custom traits or properties associated with that group.
A sample group
call is as shown:
Analytics.group(
user_id: '12345',
group_id: '12',
traits: { name: 'Company', description: 'Software'}
)
The group

traits
Object
Optional
Dictionary of the properties or traits associated with the group, such as email
or name
.
timestamp
Date
Optional
The timestamp of the message's arrival.
Alias
The alias
call lets you merge different identities of a known user.
alias
is an advanced method that lets you change the tracked user's ID explicitly. This method is useful when managing identities for some of the downstream destinations.
A sample alias
call is as shown:
Analytics.alias(previous_id: '12345', user_id: '123')
The alias
method parameters are as mentioned below:
