Pusher Beams
Pusher Beams is a managed push-notification API for iOS, Android, and web that publishes messages through a per-instance Publish API secured with a Bearer secret key. Each Beams instance gets its own `<instance-id>.pushnotifications.pusher.com` host rather than a shared endpoint, so there is no single global origin to test for CORS. A free Sandbox plan covers up to 1,000 subscribers, with paid Startup/Pro/Business/Premium tiers scaling to 250,000+ subscribers.

Auth quickstart
- Sign up with the provider to get an API key.
- Send it on every request as a header
Authorization: <key> - The exact header isn't documented — Authorization is a common default; confirm in the provider's docs.
Stored keyNo key stored
Your key is stored only in this browser (localStorage) and sent directly to the API — never to greatapis.
