Bridge // Open-Source Automation

Open-source flows, on-screen results.

Activepieces is the open-source automation platform you can self-host or run in the cloud. Add an HTTP piece to any flow and its data lands on your screens — signed, mapped, and rendered as a live table or announcement cards.

Bridge // Overview

From any Activepieces flow to any screen

Whatever your flow collects — form submissions, CRM events, support tickets, stock alerts — an HTTP piece at the end of it posts the result to your Hangar.Media inbound webhook. Because Activepieces supports code pieces, delivery can be HMAC-signed for the strongest verification, and self-hosters keep the whole pipeline on their own infrastructure.

Works with Activepieces cloud or fully self-hosted instances — no Hangar.Media-side difference
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 on-screen results.

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

Instant Push // 01

An HTTP piece is all it takes

Append an HTTP piece to any flow, point it at your inbound webhook URL, and pass whatever fields the flow has gathered. Multi-step flows can aggregate from several sources before pushing one clean payload to the screen.

If a flow can compute it, a screen can show it.

Any flow trigger works — schedules, app events, inbound webhooks

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 code piece computes an HMAC-SHA256 of the request body with your integration secret and sends it as the signature header. Hangar.Media verifies it in constant time before accepting the push; optional replay protection rejects stale requests. The simpler secret-header mode is available when you want zero code.

Every push is authenticated before a pixel changes.

HMAC-SHA256 body signing via a code piece (recommended)

Optional Stripe-style replay protection

Secret-header mode for code-free flows

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 Activepieces integration in Hangar.Media. Your unique inbound webhook URL and secret are generated instantly.

Step 02

Add an HTTP piece in Activepieces

In your flow, add the HTTP piece: method POST, your inbound webhook URL, JSON body. Sign the body in a code piece, or send the secret in the X-Webhook-Token header.

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

Best practice with Activepieces is HMAC: a code piece signs the request body with your integration secret (HMAC-SHA256) and Hangar.Media verifies the signature in constant time, with optional replay protection. A simpler secret-header mode is available for code-free flows.

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.

Does self-hosted Activepieces work

Yes — identically. The integration only receives HTTPS requests from your instance; whether it runs on Activepieces cloud or your own server makes no difference to Hangar.Media.
