Scripts run on schedule. Screens stay current.
Windmill turns scripts — TypeScript, Python, Go, Bash, SQL — into scheduled jobs and flows, self-hosted or cloud. A few lines push any result to your Hangar.Media screens, HMAC-signed.
From script result to standing display
Whatever a Windmill script computes — a database query, an API aggregation, a report — a few lines POST it to your Hangar.Media inbound webhook with an HMAC signature. Flows chain scripts and approvals; the final step is the screen.
Was Sie mit Screens stay current. tun können
Drei Funktionen, die diese Integration für Ihr Digital Signage-Netzwerk unverzichtbar machen.
A few lines in any language
Every Windmill runtime can make the push: fetch in TypeScript, requests in Python, net/http in Go. Compute the result, sign the body, POST. Schedules keep the screen current without anyone remembering to.
The cron job your whole office can see.
Flows add approval steps before the push when wording matters
JSON payloads of any shape — single records or lists
Screens update within seconds of the push arriving
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
HMAC-signed, replay-protected delivery
The script computes an HMAC-SHA256 of the body with your integration secret (stored as a Windmill resource) and sends it as X-Webhook-Signature; Hangar.Media verifies in constant time with optional replay protection.
Every push is authenticated before a pixel changes.
HMAC-SHA256 body signing in-script (recommended)
Keep the secret in a Windmill resource, not in code
Optional Stripe-style replay protection

Von der Einrichtung bis zu Live-Inhalten in Minuten, nicht Tagen.
Connect the integration
Add the Windmill integration in Hangar.Media. Your unique inbound webhook URL and secret are generated instantly.
Add the push to your script
At the end of the script or flow, build the JSON result, compute an HMAC-SHA256 with your integration secret (a Windmill resource), and POST to your inbound webhook URL with X-Webhook-Signature.
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.
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.

RetailPipeline status cards
ETL flows push run outcomes as status cards — green completions, red failures — to the ops screen.
EducationSystems report tables
Python scripts compile nightly systems reports onto the IT office screen as a live table.
HealthcareCompliance check boards
Scheduled compliance scripts push their checklists to the governance screen after each run.
Häufige Fragen. Direkte Antworten.
How is the webhook secured
Scripts sign every push — HMAC-SHA256 of the body with your integration secret (held as a Windmill resource), verified by Hangar.Media in constant time with optional replay protection.
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 Windmill work
Yes — identically to Windmill cloud. The integration receives outbound HTTPS pushes from your workers; nothing connects back into your infrastructure.
