A URL you paste into another service. Acciti verifies what that service posts, matches it against your rules and sends the notification. You don't run a handler or a server.

How does Acciti verify an incoming webhook?

Most services sign the exact bytes of each request, and Acciti checks that signature. It proves who sent the request and that nothing changed in transit. Grafana and Better Stack don't sign requests, so their connectors check a secret in a header instead.

What happens to an event with no matching rule?

Acciti records it and sends nothing. The dashboard lists every event type a connector has received without a rule, so you can write one.

Can my own server still receive the events?

Yes. Turn on forwarding and Acciti posts every verified event on to your URLs, byte for byte and signed. App Store Connect takes one notification URL per app, so this is how Acciti, your server and any other service each get them.

Stripe, GitHub and Sentry alerts on your iPhonePaste a URL. Hear every event that matters.

Add a connector, paste its URL into a service like Stripe or Sentry, and its events arrive as notifications. There's no handler to write and nothing to host.

What can Acciti connect to?

App Store, Stripe, GitHub, Provisore, Sentry, Grafana and Better Stack. Each comes with a catalogue of its events, and each event already has a priority and a message. Anything else can post signed JSON to a custom connector.

Events that mean something broke, like a monitor going down, alert from the start. Routine ones, like a sale or a merged pull request, start switched off, and you choose which to turn on.

How does Acciti know a webhook is genuine?

Every connector checks each request before it can reach your phone. How depends on the service.

Signed body

Most services sign the exact bytes they send. A valid signature proves who sent it and that nothing changed on the way.

Bearer secret

Grafana and Better Stack sign nothing, so they send a secret in a header. That proves who sent it, but not that the body arrived unchanged.

Apple's certificate chain

App Store notifications are signed by Apple. There's no shared secret on either side, and nothing to rotate.

What does an event become?

A rule turns one event into one notification, with a priority, a title and a body. It can name an escalation policy, so an unacknowledged alert reaches the next person on call.

Every kind comes with default rules, and you can edit all of them.

A rule

{  "eventType": "monitor.down",  "priority": 2,  "titleTemplate": "{{resource}} is down",  "bodyTemplate": "Provisore's monitor for {{resource}} is down as of {{timestamp}}.",  "escalation": "production"}
