## Apprise
ntfy is integrated natively into [Apprise](https://github.com/caronc/apprise) (also check out the
[Apprise/ntfy wiki page](https://github.com/caronc/apprise/wiki/Notify_ntfy)).
You can use it like this:
```
apprise -vv -t "Test Message Title" -b "Test Message Body" \
ntfy://mytopic
```
Or with your own server like this:
```
apprise -vv -t "Test Message Title" -b "Test Message Body" \
ntfy://ntfy.example.com/mytopic

### Matrix Gateway
The ntfy server implements a [Matrix Push Gateway](https://spec.matrix.org/v1.2/push-gateway-api/) (in combination with
[UnifiedPush](https://unifiedpush.org) as the [Provider Push Protocol](https://unifiedpush.org/developers/gateway/)). This makes it easier to integrate
with self-hosted [Matrix](https://matrix.org/) servers (such as [synapse](https://github.com/matrix-org/synapse)), since
you don't have to set up a separate push proxy (such as [common-proxies](https://github.com/UnifiedPush/common-proxies)).
In short, ntfy accepts Matrix messages on the `/_matrix/push/v1/notify` endpoint (see [Push Gateway API](https://spec.matrix.org/v1.2/push-gateway-api/)),
and forwards them to the ntfy topic defined in the `pushkey` of the message. The message will then be forwarded to the
ntfy Android app, and passed on to the Matrix client there.
There is a nice diagram in the [Push Gateway docs](https://spec.matrix.org/v1.2/push-gateway-api/). In this diagram, the
ntfy server plays the role of the Push Gateway, as well as the Push Provider. UnifiedPush is the Provider Push Protocol.
!!! info
This is not a generic Matrix Push Gateway. It only works in combination with UnifiedPush and ntfy.
