@tidusjar I fixed the tests :)

@gaetansnl : Hello, bonjour. Not very used of github but following up closely this change as I want to play with it ;)
Do you know if your change has been merge to "develop" branch or maybe even in "latest" one ?

Thanks,

[tidusjar]

This has not merged as of yet, I'm not sure if I'm wanting to to accept another notification provider, I'm waiting to see if anyone wants this yet as it's another integration that I would need to maintain.

@tidusjar, any update on this? Would love to see Ntfy as a notification provider.

Would love to see this as well, thanks! Honestly even if it were possible to just add a "custom/other" and allow a custom curl command or script file, as curl is one of the easiest ways to send a ntfy notification

@tidusjar : any news from this ? Ntfy is a super lightweight app and self hosted...

Would love to see this feature merged into Ombi :)

I really don't want to make this a +1 thread, but I would also appreciate this feature being added to the project.
However if you are still against this I would instead ask if the webhook notification feature could be expanded to allow custom json to be sent, so we could use it with ntfy :-D
