Bridge // Data Flows

Parabola shapes the data. Screens tell the story.

Parabola turns messy operational data — e-commerce exports, spreadsheets, APIs — into clean, scheduled data flows. An API export step pushes any flow's result table to your Hangar.Media screens.

Bridge // Overview

From messy data to a clean standing display

Parabola flows pull from Shopify, spreadsheets, email attachments and APIs, transform with visual steps, and can end with an API export that POSTs the result to your Hangar.Media inbound webhook. Each scheduled run refreshes the screen — a table of today's exceptions, a KPI set, a card board.

A flow's result table maps row-per-record onto the screen — no reshaping needed
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 Screens tell the story.

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

Instant Push // 01

The API export step is the bridge

End your flow with the API export step: method POST, your inbound webhook URL, JSON body from the flow's result table. Scheduled runs keep the display current without anyone touching it.

The ops spreadsheet, finally on the wall and always fresh.

Rows export as JSON records — one row or card each

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

Token-verified delivery

The export step sends your integration secret in the X-Webhook-Token header; Hangar.Media compares it in constant time, fail-closed, and rejects anything else with a 401.

Every push is authenticated before a pixel changes.

Constant-time secret comparison, fail-closed

One-click secret rotation

Unknown senders receive 401 and publish nothing

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

Step 02

Add an API export step in Parabola

At the end of your flow, add the API export step: method POST, your inbound webhook URL, JSON body from the result table, and a header X-Webhook-Token with your integration secret.

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

The API export step includes your integration secret in the X-Webhook-Token header; Hangar.Media compares it in constant time and rejects non-matching requests with a 401 — fail-closed, with no anonymous path.

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.

How big can the exported table be

Payloads up to 1MB are accepted — thousands of rows. For screens, less is more: use Parabola's filter and limit steps to export the rows worth showing, and the field mapper to pick the columns.
