Plugs into the screens, tills and tools you already run.

Any screen, through the Android kiosk app.

The SparkleTree kiosk app runs on Android 7.0 or newer, including Android TV boxes and sticks. Plug the device into a screen's HDMI port and the screen becomes a surface: the bar TV, the menu board, the window display or a DOOH panel.

1. Plug in and power on. The app starts on boot, asks for Wi-Fi if it needs it, and shows a pairing QR code.
2. Scan and confirm. Scan the code with your phone and confirm the screen in the dashboard. If a camera is not handy, type the activation code instead.
3. Pick what it shows. Assign a surface, full screen and touch-enabled, or with a QR code guests scan to take the campaign with them.

Provisioned as the device owner, the app locks the device to the campaign, so nobody wanders off into settings. Every screen checks in every 30 seconds with its app version and what it is playing, the dashboard flags any screen that goes quiet for two minutes, and a lost or stolen device can be quarantined or revoked from the dashboard. Screens that already have a browser can show a surface without the app.

Webhooks, in and out.

SparkleTree's webhooks are how it talks to the rest of your stack. They are managed in the dashboard, signed with HMAC-SHA256 in both directions, and have a test button, so you can check an endpoint before anything real depends on it.

Out: what SparkleTree tells your systems.

Event	When it fires
campaign.created, campaign.updated	A campaign was made or edited.
campaign.activated, campaign.deactivated	A campaign went live or came down.
campaign.approval_requested, campaign.approval_resolved	A campaign is waiting for sign-off, or got it.
analytics.alert_triggered	A metric crossed a threshold you set.
webhook.test	Sent from the dashboard to check your endpoint.

Each delivery is a JSON body with the event and a timestamp, signed in X-Webhook-Signature, with the event name in X-Webhook-Event and a delivery id in X-Webhook-Delivery that stays the same on retries. A failed delivery is retried after one, five and fifteen minutes. Subscribe to * to get everything.

In: what your systems tell SparkleTree.

Event	What it does
product.upserted, product.deleted	Create, update or remove a product: name, price, SKU, image, category and stock.
campaign.activate.requested, campaign.deactivate.requested	Start or stop a campaign from outside SparkleTree.
campaign.publish.requested, campaign.pause.requested	Publish or pause a campaign.
campaign.context.updated	Tell a live campaign what has changed, so the copy can follow.

Each integration gets its own endpoint and secret. Requests are signed, timestamped within five minutes and carry an idempotency key, so a retry is never applied twice. Secrets can be rotated, and past events can be replayed from the dashboard.

Your POS.

The till knows what is in stock and what it costs. SparkleTree knows what is being promoted, where and to whom. Webhooks keep the two in step, directly from the POS or through the integration tool you already use.

• Prices and stock in. When a price changes or the last bottle sells, the POS sends a product.upserted and the promotion works from the new numbers.
• The till starts the campaign. Happy hour opens on the POS, and a campaign.activate.requested puts it on every screen in the room.
• Your stack hears about it. When a campaign goes live, comes down or needs approval, your systems get the event and can act on it.

The screen by the till is a surface type of its own, so the last upsell before payment can be a campaign too.

Shopify.

The SparkleTree Shopify app connects your store to your workspace. Products sync as they are created, changed or removed, and new orders are matched back to the campaign that drove them, so a sale from a screen or a QR code shows up in the campaign's numbers. A web pixel attributes storefront visits. SparkleTree can write product descriptions back to Shopify once you approve them, with an undo, and create discount codes for a campaign.

Socials, ads and DOOH.

Instagram and Facebook connect through Meta: SparkleTree publishes posts, keeps the catalog in sync and can send WhatsApp templates. Bluesky posts are published and their numbers read back. Reddit and TikTok ad accounts connect in early access. For out-of-home, play confirmations from AdQuick, Vistar, Hivestack and Place Exchange come back into the campaign, next to the plays from your own screens.

Agents and your own code.

Every plan includes the SparkleTree MCP server, so Claude, Codex or any MCP client can brief, publish and measure campaigns. One script tag, or the React SDK, puts a live campaign on your own website or app. The connection details are on the developers page, and the full reference is in the documentation.
