        title: "Open CRM",
        type: "open_url",
        url: "https://crm.example.com/customers/cus_9f3a1d"
      },
      {
        title: "Chat with Jarvis",
        type: "open_url",
        url: "shortcuts://run-shortcut?name=Jarvis"
      },
      {

        }
      }
    ]
  }
)

Live Activities

Choose the Live Activity type that matches what you want to show:

Stats: Show up to 8 labeled values on your Lock Screen, from revenue and orders to uptime and conversion.

Metrics: Track two related values with segmented bars, such as CPU and memory.

Segmented Progress: Show progress through a known set of steps, like build, test, deploy, and verify.

Progress: Show percentage progress for jobs that move continuously toward completion.

Alert: Show status updates with a clear message, badge, and icon. When you add an action button, color controls the button tint.

Timer: Count down from a duration, or count up from 00:00 while a job runs.

Start & Update Live Activity

Use a stable stream_key to identify the metric, job, deployment, or system you want to keep visible. The first stream(...) call starts the Live Activity. Later calls with the same stream_key update it.

Stats

activitysmith.live_activities.stream(
  "sales-hourly",
  {
    content_state: {
      title: "Sales",
      subtitle: "last hour",
      type: "stats",
      metrics: [
        { label: "Revenue", value: "$2430", color: "blue" },
        { label: "Orders", value: "37", color: "green" },
        { label: "Conversion", value: "4.8%", color: "magenta" },
        { label: "Avg Order", value: "$65.68", color: "yellow" },
        { label: "Refunds", value: "$84", color: "red" },
        { label: "New Buyers", value: "18", color: "cyan" }
      ]
    }
  }
)

Metrics

activitysmith.live_activities.stream(
  "prod-web-1",
  {
    content_state: {
      title: "Server Health",
      subtitle: "prod-web-1",
      type: "metrics",
      metrics: [
        { label: "CPU", value: 9, unit: "%" },
        { label: "MEM", value: 45, unit: "%" }
      ]
    }
  }
)

Segmented Progress

activitysmith.live_activities.stream(
  "nightly-backup",
  {
    content_state: {
      title: "Nightly Backup",
      subtitle: "upload archive",
      type: "segmented_progress",
      number_of_steps: 3,
      current_step: 2
    }
  }
)

Progress

activitysmith.live_activities.stream(
  "search-reindex",
  {
    content_state: {
      title: "Search Reindex",
      subtitle: "catalog-v2",
      type: "progress",
      percentage: 42
    }
  }
)

Alert

activitysmith.live_activities.stream(
  "customer-ops",
  {
    content_state: ActivitySmith::LiveActivities.content_state(
      title: "Reactivation",
      message: "Lumen came back after 2 weeks",
      type: ActivitySmith::LiveActivities::TYPE_ALERT,
      icon: ActivitySmith::LiveActivities.alert_icon("cloud.sun", color: "yellow"),
      badge: ActivitySmith::LiveActivities.alert_badge("Customer", color: "magenta")
    )
  }
)

Timer

activitysmith.live_activities.stream(
  "benchmark-run",
  {
    content_state: {
      title: "Benchmark Run",
      subtitle: "sampling",
      type: "timer",
      duration_seconds: 300,
      color: "cyan"
    }
  }
)

For a countdown, send duration_seconds. You can update title, subtitle, color, or any other visible field as the work changes. Leave duration_seconds out unless you want to change the timer.

To start at 00:00 and count up, set counts_down: false and leave out duration_seconds.

End Live Activity

Call end_stream(...) with the same stream_key to dismiss the Live Activity. You can include final values before it is removed. Set auto_dismiss_seconds to dismiss it after a delay in seconds, or auto_dismiss_minutes for minutes. Use 0 for immediate dismissal. Seconds take precedence if both are set.

activitysmith.live_activities.end_stream(
  "prod-web-1",
  {
    content_state: {
      title: "Server Health",
      subtitle: "prod-web-1",
      type: "metrics",
      metrics: [
        { label: "CPU", value: 7, unit: "%" },
        { label: "MEM", value: 38, unit: "%" }
      ],
      auto_dismiss_seconds: 30
    }
  }
)

Icons and Badges

Add more context to Live Activities with icons and badges.

Icon

activitysmith.live_activities.stream(

      title: "Server Health",
      subtitle: "prod-web-1",

Lock Screen Widgets

ActivitySmith lets you display any value on your Lock Screen with widgets - SaaS metrics, revenue, signups, uptime, habits, or anything else you want to track. Create a metric in the web app, then update the metric value using our API, add a widget to your lock screen and it will fetch the latest update automatically.

Use the metric key to update its value.

activitysmith.metrics.update("deploy.success_rate", 99.9)

String metric values work too.

activitysmith.metrics.update("prod.status", "healthy")

App Icon Badge Count

Show the number you care about on your ActivitySmith app icon. Track MRR, a customer count, a stock price, or any other value you want to keep in view.

Set or update the badge value

activitysmith.badge_count(8333)

Clear the badge

Pass 0 to clear the badge.

activitysmith.badge_count(0)

Metadata

Metadata adds extra information to Push Notification and Live Activity details in ActivitySmith. It does not appear in the notification or Live Activity on your device.

activitysmith.notifications.send(
  title: "New subscription 💸",
  message: "Customer upgraded to Pro plan",
  metadata: {
    customer_id: "382",
    plan: "Pro",
    amount: 29,
    trial: false,
  }
)

activitysmith.live_activities.stream(
  "customer-import",
  content_state: {
    title: "Customer Import",
    type: "progress",
    percentage: 60,
  },
  metadata: {
    job_id: "import-382",
    records: 1200,
  }
)

Values can be strings, numbers, or booleans. Metadata supports up to 50 entries and 16 KB of JSON, with keys up to 100 characters and strings up to 4,000 characters. Nested objects, arrays, and null values are not supported.

Tags

Use tags to organize and filter your Push Notification and Live Activity history. Tags are created automatically when you first use them.

activitysmith.notifications.send(
  {
    title: "New subscription 💸",
    message: "Customer upgraded to Pro plan",
    tags: ["user:382", "billing"]
  }
)

On Live Activity stream updates and legacy update or end calls, omit tags to keep existing Tags, supply a list to replace them, or pass tags: [] to clear them.

activitysmith.live_activities.update(
  activity_id: "YOUR_ACTIVITY_ID",
  content_state: { title: "Customer Import", percentage: 60 },
  tags: []
)

Channels

Use channels to target specific team members or devices when sending Push Notifications, Live Activities, or App Icon Badge Count updates. Omit it for account-wide delivery.

activitysmith.notifications.send(
  {
    title: "New subscription 💸",
    message: "Customer upgraded to Pro plan",
    channels: ["sales", "customer-success"]
  }
)

activitysmith.live_activities.stream(
  "nightly-backup",
  {
    channels: ["ios-builds"],
    content_state: {
      title: "Nightly database backup",
      number_of_steps: 3,
      current_step: 1,
      type: "segmented_progress"
    }
  }
)

activitysmith.badge_count(3, channels: ["sales", "customer-success"])

Error Handling

Handle API errors with begin/rescue around SDK calls:

begin
  activitysmith.notifications.send(
    { title: "Hello" }
  )
rescue OpenapiClient::ApiError => err
  puts "Request failed: #{err.code} #{err.message}"
end
