[Feature Request] Support Gotify

Description

Notification settings include most systems, except the self-hosted ones. Please add support for Gotify (https://gotify.net/docs/more-pushmsg for examples with code).

Desired Behavior

A Gotify section at the URL /settings/notifications/webhook

Additional Context

Gotify supports Markdown, so it is capable of displaying images.

Currently, I have to use the webhook in order to use Gotify ~,but the webhook does not allow to use Markdown.~

If it helps, this is my current JSON payload:

{
    "title": "{{subject}}",
    "message": "notification_type: {{notification_type}}\n\nmessage: {{message}}\n\nimage: ![]({{image}})\n\n\nemail: {{notifyuser_email}}\n\nusername: {{notifyuser_username}}\n\navatar: {{notifyuser_avatar}}{{media}}:\n\n- media_type: {{media_type}}\n\n- tmdbId: {{media_tmdbid}}\n\n- imdbId: {{media_imdbid}}\n\n- tvdbId: {{media_tvdbid}}\n\n- status: {{media_status}}\n\n- status4k: {{media_status4k}}\n\n\n\n{{request}}:\n\n- request_id: {{request_id}}\n\n- requestedBy_email: {{requestedBy_email}}\n\n- requestedBy_username: {{requestedBy_username}}\n\n- requestedBy_avatar: ![]({{requestedBy_avatar}})",
    "priority": 1,
    "extras": {
        "client::display": {
            "contentType": "text/markdown"
        }
    }
}

It is hacky, not user-friendly at all, ugly, but it works. The webhook URL is http://gotify/message?token=XXXXXXX.

Edit: better JSON webhook

Ok, I will switch to the develop tag. I should have tried it before making an issue x) Thanks for the quick replies 😃

And as promised for ntfy, here’s a json payload you can use. Remember to change the https://requests.example.com to your url. And the topic too according to which topic and priority to whichever you want. With this config you can press the notification and it will direct you to the media page (as you can see with the click json key).

{
    "topic": "requests",
    "title": "{{event}}",
    "message": "{{subject}}\n{{message}}\n\nRequested by: {{requestedBy_username}}\n\nStatus: {{media_status}}\nRequest Id: {{request_id}}",
    "priority": 4,
    "attach": "{{image}}",
    "click": "https://requests.example.com/{{media_type}}/{{media_tmdbid}}"
}

with this I’m closing this issue as Gotify is already available and ntfy pre-config is provided here.
