Install with the wizard

Run this command in your project directory to add PostHog to your Ruby project. The wizard detects your framework, installs the SDK, and sets up your first events.

Or set it up manually by following the rest of this guide.

  1. Install the gem

    Required

    Add the PostHog Ruby gem to your Gemfile:

    Gemfile
    gem "posthog-ruby"

  2. Configure PostHog

    Required

    Initialize the PostHog client with your project token and host:

    Ruby
    require 'posthog'
    

    posthog = PostHog::Client.new({
        api_key: "<ph_project_token>",
        host: "https://us.i.posthog.com",
        on_error: Proc.new { |status, msg| print msg }
    })

  3. Send events

    Recommended

    Once installed, you can manually send events to test your integration:

    Ruby
    posthog.capture({
        distinct_id: 'user_123',
        event: 'button_clicked',
        properties: {
            button_name: 'signup'
        }
    })

  4. Manually capture exceptions

    Required

    Using Ruby on Rails? The posthog-rails gem provides automatic exception capture for controllers and background jobs. Select "Ruby on Rails" from the SDK list for setup instructions.

    To capture exceptions in your Ruby application, use the capture_exception method:

    Ruby
    begin
      # Code that might raise an exception
      raise StandardError, "Something went wrong"
    rescue => e
      posthog.capture_exception(
        e,
        'user_distinct_id',
        {
          custom_property: 'custom_value'
        }
      )
    end

    The capture_exception method accepts the following parameters:

    ParamTypeDescription
    exceptionExceptionThe exception object to capture (required)
    distinct_idStringThe distinct ID of the user (optional)
    additional_propertiesHashAdditional properties to attach to the exception event (optional)

  5. Verify error tracking

    Recommended
    Confirm events are being sent to PostHog
    Before proceeding, let's make sure exception events are being captured and sent to PostHog. You should see events appear in the activity feed.
    Activity feed with events
    Check for exceptions in PostHog
  6. Optional

    Great, you're capturing exceptions! To see which release each exception comes from, give your app the release ID when you deploy.
