VAPID Key Generator
Generate VAPID key pairs for authenticating your server with push services.
How this tool works
This tool signs and sends a single Web Push request using your VAPID keys and subscription data.
Paste the subscription endpoint and keys from your browser, then send a payload. The request is signed with your VAPID keys and sent to the browser's push service.
Server-side config
Store the VAPID keys on the server and send the signed request to the subscription endpoint.
Client and user side
Ask for permission, subscribe with the Push API, and copy the endpoint + keys into this form.
Security note: Keys and payloads are used to send the request and are not stored. Treat private keys like passwords and only paste them here for testing. DO NOT paste your production keys here.
Web Push Sender Questions
Common questions about sending and debugging web push notifications.
What do I need to send a web push notification?
You need a VAPID key pair, a push subscription from the user's browser, and a payload to send. The subscription contains the endpoint URL and encryption keys. This tool combines all three to sign and deliver a single push message from our server.
How do I get a push subscription object?
Call registration.pushManager.subscribe() in the browser after the user grants notification permission. The returned PushSubscription object contains the endpoint, p256dh key, and auth secret that you paste into this tool.
Why did my web push notification fail to deliver?
Common causes include an expired subscription, mismatched VAPID keys, or the browser's push service being temporarily unavailable. Check the HTTP status code returned by the push service: 201 means success, 410 means the subscription is gone, and 403 usually indicates a VAPID authentication error.
