New Notification

🔖 Feature description

Ntfy as a notification agent, it is a rapidly growing very popular sub-pub notification service and I know lots of people who want this to be included in uptime kuma as they both would go extremely well together.

✔️ Solution

https://ntfy.sh/docs

Allow publishing via http or curl with options to change tags,topic,message,title, and priority, examples below:

HTTP:

POST / HTTP/1.1
Host: example..com

{
    "topic": "uptimekuma",
    "message": "Site is down",
    "title": "Site Down Alert",
    "tags": ["warning","loudspeaker"],
    "priority": 4
}

Curl:

curl ntfy.sh \
  -d '{
    "topic": "uptimekuma",
    "message": "Site is down",
    "title": "Low disk space alert",
    "tags": ["warning","loudspeaker"],
    "priority": 4
  }'

Yes, it will be in the next release.

At the meantime, if you are using Docker, you can use Ntfy via Apprise in Uptime Kuma 1.16.1
