I see references to ntfy in the shoutrrr codebase (which is what Scrutiny uses for handling notifications to external services) -- it may already be supported, however their documentation site implies its only available in the dev branch https://containrrr.dev/shoutrrr/dev/services/ntfy/

You can use a webhook for ntfy like this:

version: 1
notify:
    urls:
        - "https://ntfy.sh/xxxx"

For authorization (with user:pass or a token), see https://docs.ntfy.sh/publish/#query-param

Oh yeah that works! Although the payload is sent as is so no formatting right? I think for the time being I'll just create a webhook server and then divert the payload to ntfy for the time being 🤔

Yeah it's sent as JSON, maybe there should be/is an option to just send it as text?

looks like shoutrrr v7.1 has been released. This should be a fairly easy upgrade (and will natively support ntfy).
