# Show reported events

This API returns information about reported events.

To use it, you will need to authenticate by providing an `access_token`
for a server admin: see [Admin API](../usage/administration/admin_api).

The api is:
```
GET /_synapse/admin/v1/event_reports?from=0&limit=10
```

It returns a JSON body like the following:

```json
{
    "event_reports": [
        {
            "event_id": "$bNUFCwGzWca1meCGkjp-zwslF-GfVcXukvRLI1_FaVY",
            "id": 2,
            "reason": "foo",
            "score": -100,
            "received_ts": 1570897107409,
            "canonical_alias": "#alias1:matrix.org",
            "room_id": "!ERAgBpSOcCCuTJqQPk:matrix.org",
            "name": "Matrix HQ",
            "sender": "@foobar:matrix.org",
            "user_id": "@foo:matrix.org"
        },
        {
            "event_id": "$3IcdZsDaN_En-S1DF4EMCy3v4gNRKeOJs8W5qTOKj4I",
            "id": 3,
            "reason": "bar",
            "score": -100,
            "received_ts": 1598889612059,
            "canonical_alias": "#alias2:matrix.org",
            "room_id": "!eGvUQuTCkHGVwNMOjv:matrix.org",
            "name": "Your room name here",
            "sender": "@foobar:matrix.org",
            "user_id": "@bar:matrix.org"
        }
    ],
    "next_token": 2,
    "total": 4
}
```

To paginate, check for `next_token` and if present, call the endpoint again with `from`
set to the value of `next_token`. This will return a new page.

If the endpoint does not return a `next_token` then there are no more reports to
paginate through.

**URL parameters:**

* `limit`: integer - Is optional but is used for pagination, denoting the maximum number
  of items to return in this call. Defaults to `100`.
* `from`: integer - Is optional but used for pagination, denoting the offset in the
  returned results. This should be treated as an opaque value and not explicitly set to
  anything other than the return value of `next_token` from a previous call. Defaults to `0`.
* `dir`: string - Direction of event report order. Whether to fetch the most recent
  first (`b`) or the oldest first (`f`). Defaults to `b`.
* `user_id`: string - Is optional and filters to only return users with user IDs that
  contain this value. This is the user who reported the event and wrote the reason.
* `room_id`: string - Is optional and filters to only return rooms with room IDs that
  contain this value.

**Response**

The following fields are returned in the JSON response body:

* `id`: integer - ID of event report.
* `received_ts`: integer - The timestamp (in milliseconds since the unix epoch) when this
  report was sent.
* `room_id`: string - The ID of the room in which the event being reported is located.
* `name`: string - The name of the room.
* `event_id`: string - The ID of the reported event.
* `user_id`: string - This is the user who reported the event and wrote the reason.
* `reason`: string - Comment made by the `user_id` in this report. May be blank or `null`.
* `score`: integer - Content is reported based upon a negative score, where -100 is
  "most offensive" and 0 is "inoffensive". May be `null`.
* `sender`: string - This is the ID of the user who sent the original message/event that
  was reported.
* `canonical_alias`: string - The canonical alias of the room. `null` if the room does not
  have a canonical alias set.
* `next_token`: integer - Indication for pagination. See above.
* `total`: integer - Total number of event reports related to the query
  (`user_id` and `room_id`).
