Bridge // Signed Flows

Celigo moves the orders. Screens move the team.

Celigo integrator.io is the iPaaS behind thousands of NetSuite and e-commerce stacks. End any flow with an HTTP import pointed at your Hangar.Media inbound webhook — with native handlebars HMAC signing, it is one of the few platforms where signed delivery needs no code at all.

Bridge // Overview

The NetSuite-grade pipeline, ending on glass

Flows that already sync orders, inventory, and fulfilment can branch their result to a screen: an HTTP import POSTs the records to your inbound webhook on every run. Celigo’s hmacOptions template helpers compute the HMAC-SHA256 body signature inside the mapping — signed delivery without a script.

End any flow with an HTTP import targeting your webhook URL
Native hmacOptions handlebars compute the HMAC-SHA256 signature — no code step 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
Outbound events included: screens can hit Celigo webhook listeners back (offline/online, sync errors, emergency alerts) with a signed envelope
Bridge // Key Features

What you can do with Screens move the team.

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

Instant Push // 01

The HTTP import is the bridge

Add an HTTP import as a flow destination: method POST, your inbound webhook URL, JSON body built from the flow’s records. Each flow run delivers straight to the bound widget.

The flow that syncs the store also feeds the wall.

Flow records post as JSON — single records or batches

Scheduled and event-driven flows both work

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
Signed Delivery // 03

HMAC-signed delivery

Sign the request body with your integration secret (HMAC-SHA256) and send the digest as X-Webhook-Signature; Hangar.Media recomputes and compares in constant time, fail-closed. The simpler X-Webhook-Token header mode is available too.

The body itself is proven authentic — not just the sender.

HMAC-SHA1/256/512 accepted, SHA-256 recommended

Constant-time comparison, fail-closed

Token-header mode available as the simple alternative

Bridge // Signed Delivery
Bridge // Setup

Four steps to connected screens.

From setup to live content in minutes, not days.

Step 01

Connect the integration

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

Step 02

Add an HTTP import in integrator.io

Add an HTTP import as the flow destination: method POST, your inbound webhook URL, JSON body. Use hmacOptions in the request template to sign the body as X-Webhook-Signature — or simply send the X-Webhook-Token header.

Step 03

Map fields to the display

Choose Data Table, Content Cards, or KPI Metrics, 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

Two modes: sign the body with HMAC-SHA256 via Celigo’s native hmacOptions helpers and send X-Webhook-Signature (recommended), or send the integration secret in the X-Webhook-Token header. Both are compared in constant time, fail-closed.

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.

Why is HMAC recommended over the token header

The HMAC signature proves the request body itself was produced by a sender holding the secret — a stronger guarantee than presenting the secret as a header. Celigo computes it natively in the request template, so the stronger mode costs nothing.
