Installation

go get github.com/ActivitySmithHQ/activitysmith-go

Setup

package main

import (
	"log"

	activitysmithsdk "github.com/ActivitySmithHQ/activitysmith-go"
)

func main() {
	activitysmith, err := activitysmithsdk.New("YOUR_API_KEY")
	if err != nil {
		log.Fatal(err)
	}

	_ = activitysmith
}

Push Notifications

Send a Push Notification

Use activitysmith.Notifications.Send with either activitysmithsdk.PushNotificationInput for common notification fields or generated.PushNotificationRequest if you want full control over the generated model.

input := activitysmithsdk.PushNotificationInput{
	Title:   "New subscription 💸",
	Message: "Customer upgraded to Pro plan",
}

_, err := activitysmith.Notifications.Send(input)
if err != nil {
	log.Fatal(err)
}

Rich Push Notifications with Media

input := activitysmithsdk.PushNotificationInput{
	Title:       "Homepage ready",
	Message:     "Your agent finished the redesign.",
	Media:       "https://cdn.example.com/output/homepage-v2.png",
	Redirection: "https://github.com/acme/web/pull/482",
}

_, err := activitysmith.Notifications.Send(input)
if err != nil {
	log.Fatal(err)
}

Send images, videos, or audio with your push notifications, press and hold to preview media directly from the notification, then tap through to open the linked content.

What will work:

• direct image URL: .jpg, .png, .gif, etc.
• direct audio file URL: .mp3, .m4a, etc.
• direct video file URL: .mp4, .mov, etc.
• URL that responds with a proper media Content-Type, even if the path has no extension

Actionable Push Notifications

Actionable push notifications can open a URL on tap or trigger actions when someone long-presses the notification. Webhooks are executed by the ActivitySmith backend.

_, err := activitysmith.Notifications.Send(activitysmithsdk.PushNotificationInput{
	Title:       "New subscription 💸",
	Message:     "Customer upgraded to Pro plan",
	Redirection: "https://crm.example.com/customers/cus_9f3a1d",
	Actions: []activitysmithsdk.PushNotificationAction{
		activitysmithsdk.PushAction(
			"Open CRM Profile",
			"open_url",
			"https://crm.example.com/customers/cus_9f3a1d",
		),
		activitysmithsdk.PushAction(
			"Start Onboarding Workflow",
			"webhook",
			"https://hooks.example.com/activitysmith/onboarding/start",
			activitysmithsdk.PushActionMethod("POST"),
			activitysmithsdk.PushActionBody(map[string]interface{}{
				"customer_id": "cus_9f3a1d",
				"plan":        "pro",
			}),
		),
	},
})
if err != nil {
	log.Fatal(err)
}

Live Activities

There are five types of Live Activities:

• stats: best for showing business numbers side by side, such as revenue, sales, new users, conversion, refunds, or any other value you want visible at a glance
• metrics: best for live percentage values that change often, like server CPU, memory usage, disk usage, or error rate
• segmented_progress: best for anything that moves through clear stages, like deployments, onboarding flows, backups, ETL pipelines, migrations, and AI agent runs
• progress: best for tracking real-time progress with percentage, like tasks, backups, migrations, syncs, or uploads
• alert: best for status updates, such as feature adoption, reactivation, onboarding blockers, incidents, escalations, and other operational states

Start & Update Live Activity

Use a stable streamKey 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 streamKey update it.

Stats

activitysmith.LiveActivities.Stream(
	"sales-hourly",
	activitysmithsdk.LiveActivityStreamInput{
		Title:    "Sales",
		Subtitle: "last hour",
		Type:     "stats",
		Metrics: []activitysmithsdk.ActivityMetric{
			activitysmithsdk.Metric("Revenue", "$2430", activitysmithsdk.MetricColor("blue")),
			activitysmithsdk.Metric("Orders", "37", activitysmithsdk.MetricColor("green")),
			activitysmithsdk.Metric("Conversion", "4.8%", activitysmithsdk.MetricColor("magenta")),
			activitysmithsdk.Metric("Avg Order", "$65.68", activitysmithsdk.MetricColor("yellow")),
			activitysmithsdk.Metric("Refunds", "$84", activitysmithsdk.MetricColor("red")),
			activitysmithsdk.Metric("New Buyers", "18", activitysmithsdk.MetricColor("cyan")),
		},
	},
)

Metrics

activitysmith.LiveActivities.Stream(
	"prod-web-1",
	activitysmithsdk.LiveActivityStreamInput{
		Title:    "Server Health",
		Subtitle: "prod-web-1",
		Type:     "metrics",
		Metrics: []activitysmithsdk.ActivityMetric{
			activitysmithsdk.Metric("CPU", 9, activitysmithsdk.MetricUnit("%")),
			activitysmithsdk.Metric("MEM", 45, activitysmithsdk.MetricUnit("%")),
		},
	},
)

Segmented Progress

activitysmith.LiveActivities.Stream(
	"nightly-backup",
	activitysmithsdk.LiveActivityStreamInput{
		Title:         "Nightly Backup",
		Subtitle:      "upload archive",
		Type:          "segmented_progress",
		NumberOfSteps: 3,
		CurrentStep:   2,
	},
)

Progress

activitysmith.LiveActivities.Stream(
	"search-reindex",
	activitysmithsdk.LiveActivityStreamInput{
		Title:      "Search Reindex",
		Subtitle:   "catalog-v2",
		Type:       "progress",
		Percentage: 42,
	},
)

Alert

activitysmith.LiveActivities.Stream(
	"customer-ops",
	activitysmithsdk.LiveActivityStreamInput{
		Title:   "Reactivation",
		Message: "Lumen came back after 2 weeks",
		Type:    activitysmithsdk.LiveActivityTypeAlert,
		Icon:    activitysmithsdk.AlertIcon("cloud.sun", "yellow"),
		Badge:   activitysmithsdk.AlertBadge("Customer", "magenta"),
	},
)

End Live Activity

Call EndStream(...) with the same streamKey to dismiss the Live Activity. You can include final values before it is removed. By default, iOS removes the Live Activity after two minutes. Set AutoDismissMinutes to choose a different dismissal time, including 0 for immediate dismissal.

activitysmith.LiveActivities.EndStream(
	"prod-web-1",
	activitysmithsdk.LiveActivityStreamEndInput{
		Title:    "Server Health",
		Subtitle: "prod-web-1",
		Type:     "metrics",
		Metrics: []activitysmithsdk.ActivityMetric{
			activitysmithsdk.Metric("CPU", 7, activitysmithsdk.MetricUnit("%")),
			activitysmithsdk.Metric("MEM", 38, activitysmithsdk.MetricUnit("%")),
		},
		AutoDismissMinutes: 2,
	},
)

Live Activity Action

Live Activities can include one optional action button. Use it to open a URL from the Live Activity or trigger a backend webhook. For Alert Live Activities, set Color to tint the action button. The icon and badge colors only affect the icon and badge.

Open URL action

activitysmith.LiveActivities.Stream(
	"prod-web-1",
	activitysmithsdk.LiveActivityStreamInput{
		Title:    "Server Health",
		Subtitle: "prod-web-1",
		Type:     "metrics",
		Metrics: []activitysmithsdk.ActivityMetric{
			activitysmithsdk.Metric("CPU", 76, activitysmithsdk.MetricUnit("%")),
			activitysmithsdk.Metric("MEM", 52, activitysmithsdk.MetricUnit("%")),
		},
		Action: &activitysmithsdk.LiveActivityActionInput{
			Title: "Open Dashboard",
			Type:  "open_url",
			URL:   "https://ops.example.com/servers/prod-web-1",
		},
	},
)

Webhook action

activitysmith.LiveActivities.Stream(
	"search-reindex",
	activitysmithsdk.LiveActivityStreamInput{
		Title:         "Reindexing product search",
		Subtitle:      "Shard 7 of 12",
		Type:          "segmented_progress",
		NumberOfSteps: 12,
		CurrentStep:   7,
		Action: &activitysmithsdk.LiveActivityActionInput{
			Title:  "Pause Reindex",
			Type:   "webhook",
			URL:    "https://ops.example.com/hooks/search/reindex/pause",
			Method: "POST",
			Body: map[string]interface{}{
				"job_id":       "reindex-2026-03-19",
				"requested_by": "activitysmith-go",
			},
		},
	},
)

Icons and Badges

Add more context to Live Activities with icons and badges.

Icon

Supported Live Activity types: stats, metrics, progress, segmented_progress, and alert.

activitysmith.LiveActivities.Stream(
	"prod-web-1",
	activitysmithsdk.LiveActivityStreamInput{
		Title:    "Server Health",
		Subtitle: "prod-web-1",
		Type:     "metrics",
		Icon:     activitysmithsdk.AlertIcon("server.rack", "blue"),
		Metrics: []activitysmithsdk.ActivityMetric{
			activitysmithsdk.Metric("CPU", 18, activitysmithsdk.MetricUnit("%")),
			activitysmithsdk.Metric("MEM", 42, activitysmithsdk.MetricUnit("%")),
		},
	},
)

The Icon symbol value is an Apple SF Symbol name. Browse the catalog with one of these tools:

• ActivitySmith app - Open Settings -> SF Symbols to browse 45 hand-picked icons ready to use
• SF Symbols - Apple's official macOS app
• Interactful - free third-party iOS app listing all SF Symbols under Foundations -> Iconography

Badge

Badges are supported by alert, progress, and segmented_progress Live Activities.

activitysmith.LiveActivities.Stream(
	"nightly-database-backup",
	activitysmithsdk.LiveActivityStreamInput{
		Title:      "Nightly Database Backup",
		Subtitle:   "verify restore",
		Type:       "progress",
		Badge:      activitysmithsdk.AlertBadge("S3", "cyan"),
		Percentage: 62,
	},
)

Live Activity Colors

Choose from these colors for the Live Activity accent, including progress bars and action buttons, or apply them to an individual icon or badge:

lime, green, cyan, blue, purple, magenta, red, orange, yellow, gray

Channels

Channels are used to target specific team members or devices. Can be used for both push notifications and live activities.

request := generated.NewPushNotificationRequest("New subscription 💸")
request.SetMessage("Customer upgraded to Pro plan")
request.SetTarget(generated.ChannelTarget{Channels: []string{"sales", "customer-success"}}) // Optional

_, err := activitysmith.Notifications.Send(request)
if err != nil {
	log.Fatal(err)
}

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.

_, err := activitysmith.Metrics.Update("deploy.success_rate", 99.9)
if err != nil {
	log.Fatal(err)
}

String metric values work too.

_, err = activitysmith.Metrics.Update("prod.status", "healthy")
if err != nil {
	log.Fatal(err)
}

Error Handling

SDK methods return (response, error). Always check error on each call.
