NEXOS CORE can send browser push notifications using Web Push (VAPID), so you get native desktop/mobile alerts even when the NEXOS CORE tab isn’t focused. Subscriptions are stored per user (per browser), and signing keys are held per tenant.

​
When to use it

  • Get notified of things that need attention — like a purchase-order approval request — without watching the app.
  • Opt a browser in to push notifications.
  • Opt a browser back out (unsubscribe) on a shared or retired device.

​
How it works

1

Subscribe your browser

Your browser fetches the tenant’s public VAPID key and registers a push subscription; NEXOS CORE stores the endpoint and keys against your user.
2

NEXOS CORE delivers

When an event fires (e.g. a PO approval), NEXOS CORE pushes to all of your subscribed browsers. Notifications arrive even with the tab in the background.
3

Cleanup is automatic

Subscriptions a browser has revoked are detected and removed automatically.
The tenant’s VAPID keypair is generated automatically the first time it’s needed.

​
Good to know

  • Push is opt-in per browser — you won’t receive notifications until you subscribe, and you subscribe separately on each device/browser.
  • Requires a browser that supports the Web Push API and service workers (Chrome/Edge/Firefox; Safari requires a recent macOS/iOS with the app installed as a PWA).
  • Delivery is best-effort — a failed push is logged and retried on the next event, not surfaced as an error.
