How to notify on every new post for a specific community?

Is it possible for Lemmy to send me a notification whenever somebody submits a new post to a specific community (one that I own)?

I started a project-specific community !ntfy@discuss.ntfy.sh that's supposed to be a support forum, and I have missed a few posts for many hours because there are no notifications.

I'd be ok too if there was a simple API and I'd have to write a small script, but it'd be nicer if it was built-in

!hdev@lemmy.world has an automod bot, I'm just testing it too. Lemmy.world's api is inconsistent, but maybe that won't be a problem on your instance.

@Rooki@lemmy.world ?
- That implies that it's not a native feature. I gotta find the API docs then...
  
  Edit: Looks like there is an easy-ish API. Examples:
  
  $ curl -s "https://discuss.ntfy.sh/api/v3/post/list?sort=Hot"|jq '.posts[].post.name' "Docker-compose + Traefik" "[SOLVED] Self-hosted NTFY does not receive all notifications" "Markdown is coming soon ... 🤩 😲" "[disscussion] Lemmy push notifications with ntfy" "Using healthchecks.io and ntfy.sh to wake you up if your services are down" "Ntfy Connector: Modal-based discord bot to send,and now receive, ntfy notifications." "Welcome to the new ntfy discussion board" "ntfy Web Push / PWA support is coming soon" "📢 ntfy Web Push / PWA: Request for testing!" "ntfy release 🎉 - Now with Web Push and a progressive web app (hello iOS friends ❤️), and with dark mode for the web app! ntfy lets you send push notifications to your phone via a simple REST API, and"
  
  You have to fetch every comment every post every few minutes and save the ids somewhere.
  
  I suggest you ( if you are a js programmer ) https://github.com/SleeplessOne1917/lemmy-bot , it fetches the newest posts, comments and saves it for persistency in a database, so that you dont get every 30 seconds notified.
  
  If you want i can set up the bot for you or just guide you how you could do it :) If you want i can even host the bot on my server.
  
  edit: if you want you can do it over with curl but its difficult because it sends you every post. not unread ones. ( and search sort for "new" for best results )
  
  Thanks dude. I'm going to try the curl route. What do you mean by it sends you every post? Isn't that what I want?
  
  Yeah but you would have to know what posts are new and not already known.
  
  That's what saving the IDs is for right? It's easy enough to do in a bash script I think. I'll post it here later, assuming I get it to work.
  
  But i would not know how to save the ids there. But good luck :)
  
  Here ya go. ChatGPT did all the hard work: https://chat.openai.com/share/7703dbe5-6801-4d5b-8d56-c3f18ca3ac4a
  
  Edit: here's a manually refined version: https://gist.github.com/binwiederhier/70f13b7c7338a2b75e15438b5567a6d6
  
  Ah ok now i know how to save things in files with bash :)
