Clients may want to receive push notifications when events are received
|
|
at the homeserver. This is managed by a distinct entity called the Push
|
|
Gateway.

## Overview
|
|
|
|
A client's homeserver forwards information about received events to the
|
|
push gateway. The gateway then submits a push notification to the push
|
|
notification provider (e.g. APNS, GCM).

## Homeserver behaviour
|
|
|
|
This describes the format used by "HTTP" pushers to send notifications
|
|
of events to Push Gateways. If the endpoint returns an HTTP error code,
|
|
the homeserver SHOULD retry for a reasonable amount of time using
|
|
exponential backoff.
|
|
|
|
When pushing notifications for events, the homeserver is expected to
|
|
include all of the event-related fields in the `/notify` request. When
|
|
the homeserver is performing a push where the `format` is
|
|
`"event_id_only"`, only the `event_id`, `room_id`, `counts`, and
|
|
`devices` are required to be populated.
|
|
|
|
Note that most of the values and behaviour of this endpoint is described
|
|
by the Client-Server API's [Push
|
|
Module](/client-server-api#push-notifications).
