# List all media in a room
This API gets a list of known media in a room.
The API is:
```
GET /_matrix/client/r0/admin/room/<room_id>/media
```
including an `access_token` of a server admin.
It returns a JSON body like the following:
```
{
"local": [
"mxc://localhost/xwvutsrqponmlkjihgfedcba",
"mxc://localhost/abcdefghijklmnopqrstuvwx"
],
"remote": [
"mxc://matrix.org/xwvutsrqponmlkjihgfedcba",
"mxc://matrix.org/abcdefghijklmnopqrstuvwx"
]
}
```

@ -4,8 +4,6 @@ Purge History API
The purge history API allows server admins to purge historic events from their
database, reclaiming disk space.
**NB!** This will not delete local events (locally sent messages content etc) from the database, but will remove lots of the metadata about them and does dramatically reduce the on disk space usage
Depending on the amount of history being purged a call to the API may take
several minutes or longer. During this period users will not be able to
paginate further back in the room from the point being purged from.
@ -15,3 +13,15 @@ The API is simply:
``POST /_matrix/client/r0/admin/purge_history/<room_id>/<event_id>``
including an ``access_token`` of a server admin.
By default, events sent by local users are not deleted, as they may represent
the only copies of this content in existence. (Events sent by remote users are
deleted, and room state data before the cutoff is always removed).
To delete local events as well, set ``delete_local_events`` in the body:
.. code:: json
{
"delete_local_events": True,
}
