Bridge // Low-Code Scenarios

Low-code scenarios, high-visibility screens.

Latenode mixes visual nodes with real JavaScript. End any scenario with an HTTP request — or a JS node that signs the payload — and the result renders on your Hangar.Media screens as a live table or announcement cards.

Bridge // Overview

Scenarios that end on screen

Latenode scenarios can call APIs, run headless browsers, and execute JavaScript with NPM packages — then push the result to your Hangar.Media inbound webhook. With a JS node computing an HMAC of the body, delivery uses the strongest verification mode available.

JavaScript nodes with NPM access can shape and sign the exact payload your screens need
Map any payload field to display columns with dot-notation paths, defaults, and per-column transforms
Three display targets: live data table, announcement cards (with rolling accumulation), or KPI metrics
Accumulate mode keeps a rolling board of the most recent pushes instead of replacing on every update
Outbound events included: screens can trigger your automations back (offline/online, sync errors, emergency alerts) with a signed envelope
Bridge // Key Features

What you can do with high-visibility screens.

Three capabilities that make this integration essential for your digital signage network.

Instant Push // 01

HTTP node or JavaScript node — your choice

Use the HTTP Request node for a quick POST, or a JavaScript node when you want to aggregate, reshape, and sign the payload in code before it leaves the scenario.

From scraped page to signed payload to screen, in one scenario.

Headless-browser and API steps can feed the same final push

JSON payloads of any shape — single records or lists

Screens update within seconds of the push arriving

Bridge // Instant Push
Field Mapping // 02

Shape the payload into screen content

Point display columns at payload fields with dot-notation paths, set defaults for missing fields, and apply per-column transforms — uppercase, lowercase, truncate, prefix, suffix. The same mapping engine powers every automation platform integration, so a recipe built once is portable across tools.

Your automation sends data; the mapping decides how it reads on screen.

Dot-notation paths reach nested payload fields

Defaults fill gaps so screens never show blanks

Transforms tidy values without touching the automation

Bridge // Field Mapping
Verified Delivery // 03

HMAC-signed, replay-protected delivery

A JavaScript node computes an HMAC-SHA256 of the request body with your integration secret and sends it as the signature header; Hangar.Media verifies in constant time with optional replay protection. The secret-header mode remains available for node-only scenarios.

Every push is authenticated before a pixel changes.

HMAC-SHA256 body signing in a JS node (recommended)

Optional Stripe-style replay protection

Secret-header mode for node-only scenarios

Bridge // Verified Delivery
Bridge // Setup

Four steps to connected screens.

From setup to live content in minutes, not days.

Step 01

Connect the integration

Add the Latenode integration in Hangar.Media. Your unique inbound webhook URL and secret are generated instantly.

Step 02

Add the push step in Latenode

End the scenario with an HTTP Request node (POST, your inbound webhook URL, JSON body) — or a JavaScript node that signs the body with HMAC-SHA256 and sends X-Webhook-Signature.

Step 03

Map fields to the display

Choose Data Table or Content Cards, then map payload fields to display columns with the field mapper. Defaults and transforms are optional.

Step 04

Push and publish

Run the automation. The payload renders in the bound widget on your screens within seconds — enable Accumulate for a rolling board of recent pushes.

Bridge // Questions

Common questions. Straight answers.

How is the webhook secured

Recommended setup signs every push: a JavaScript node computes an HMAC-SHA256 of the body with your integration secret, and Hangar.Media verifies it in constant time with optional replay protection. A secret-header mode exists for scenarios without code nodes.

What payload shape does Hangar.Media expect

Any JSON. A single object becomes one row or card; an array of objects becomes one row or card per record. With a field mapping configured, only the mapped fields are displayed; without one, the raw fields are shown as a key-value table.

Can one push update several screens

Yes. The push lands in the integration's data feed; every design widget bound to that feed updates, wherever those designs are scheduled — one push can update one screen or the whole estate.

Can Latenode shape the payload before pushing

Yes — that is its strength. JavaScript nodes (with NPM packages) can aggregate several sources, rename fields, and emit exactly the JSON your field mapping expects.
