Notifications from anything you run

Notifications that ask.

Your script asks Deploy v2.4 to production? You tap Approve on the notification, and the script gets a signed answer.

Approve or deny, yes or no, or up to three answers you write, such as Ship it, Hold or Roll back
One answer per notification, recorded once. You choose how long it stays open, from ten seconds to seven days
Your code hears the answer by a callback signed with your secret, or asks for the receipt when it likes
Answer from your iPhone or your Mac

delivered is how many of your devices Apple accepted it for. Send a dedupe_key and the same alert arriving twice is delivered once, so a job that retries on a schedule cannot wake you again.

How it works.

Three steps from opening the app to your first notification from a script.

Get it free from the App Store, allow notifications, then tap Send a Test.

Settings › Connect an App › Create Your Key. It can only send: a leaked key can't read your history or touch your account.

Paste one command into your script or terminal. Settings › Connect an App has the address, the key and the line, ready to copy.

Already using Prowl or ntfy?

Change the address and the key. Everything else stays as it is.

Coming from Prowl?

Point your script at Nowlark and use a Nowlark key. Nothing else changes.

The add and verify calls work as on Prowl: the same fields, replies and priorities.

Using an app with an ntfy option?

Choose ntfy, set the server and paste your key as the access token.
