+# List Room API
+
+The List Room admin API allows server admins to get a list of rooms on their
+server. There are various parameters available that allow for filtering and
+sorting the returned list. This API supports pagination.
+
+## Parameters
+
+The following query parameters are available:
+
+* `from` - Offset in the returned list. Defaults to `0`.
+* `limit` - Maximum amount of rooms to return. Defaults to `100`.
+* `order_by` - The method in which to sort the returned list of rooms. Valid values are:
+  - `alphabetical` - Rooms are ordered alphabetically by room name. This is the default.
+  - `size` - Rooms are ordered by the number of members. Largest to smallest.
+* `dir` - Direction of room order. Either `f` for forwards or `b` for backwards. Setting
+          this value to `b` will reverse the above sort order. Defaults to `f`.
+* `search_term` - Filter rooms by their room name. Search term can be contained in any
+                  part of the room name. Defaults to no filtering.
+
+The following fields are possible in the JSON response body:
+
+* `rooms` - An array of objects, each containing information about a room.
+  - Room objects contain the following fields:
+    - `room_id` - The ID of the room.
+    - `name` - The name of the room.
+    - `canonical_alias` - The canonical (main) alias address of the room.
+    - `joined_members` - How many users are currently in the room.
+* `offset` - The current pagination offset in rooms. This parameter should be
+             used instead of `next_token` for room offset as `next_token` is
+             not intended to be parsed.
+* `total_rooms` - The total number of rooms this query can return. Using this
+                  and `offset`, you have enough information to know the current
+                  progression through the list.
+* `next_batch` - If this field is present, we know that there are potentially
+                 more rooms on the server that did not all fit into this response.
+                 We can use `next_batch` to get the "next page" of results. To do
+                 so, simply repeat your request, setting the `from` parameter to
+                 the value of `next_batch`.
+* `prev_batch` - If this field is present, it is possible to paginate backwards.
+                 Use `prev_batch` for the `from` value in the next request to
+                 get the "previous page" of results.
+
+## Usage
+
+A standard request with no filtering:
+
+```
+GET /_synapse/admin/rooms
+
+{}
+```
+
+Response:
+
+```
+{
+  "rooms": [
+    {
+      "room_id": "!OGEhHVWSdvArJzumhm:matrix.org",
+      "name": "Matrix HQ",
+      "canonical_alias": "#matrix:matrix.org",
+      "joined_members": 8326
+    },
+    ... (8 hidden items) ...
+    {
+      "room_id": "!xYvNcQPhnkrdUmYczI:matrix.org",
+      "name": "This Week In Matrix (TWIM)",
+      "canonical_alias": "#twim:matrix.org",
+      "joined_members": 314
+    }
+  ],
+  "offset": 0,
+  "total_rooms": 10
+}
+```
+
+Filtering by room name:
+
+```
+GET /_synapse/admin/rooms?search_term=TWIM
+
+{}
+```
+
+Response:
+
+```
+{
+  "rooms": [
+    {
+      "room_id": "!xYvNcQPhnkrdUmYczI:matrix.org",
+      "name": "This Week In Matrix (TWIM)",
+      "canonical_alias": "#twim:matrix.org",
+      "joined_members": 314
+    }
+  ],
+  "offset": 0,
+  "total_rooms": 1
+}
+```
+
+Paginating through a list of rooms:
+
+```
+GET /_synapse/admin/rooms?order_by=size
+
+{}
+```
+
+Response:
+
+```
+{
+  "rooms": [
+    {
+      "room_id": "!OGEhHVWSdvArJzumhm:matrix.org",
+      "name": "Matrix HQ",
+      "canonical_alias": "#matrix:matrix.org",
+      "joined_members": 8326
+    },
+    ... (98 hidden items) ...
+    {
+      "room_id": "!xYvNcQPhnkrdUmYczI:matrix.org",
+      "name": "This Week In Matrix (TWIM)",
+      "canonical_alias": "#twim:matrix.org",
+      "joined_members": 314
+    }
+  ],
+  "offset": 0,
+  "total_rooms": 150
+  "next_token": 100
+}
+```
+
+The presence of the `next_token` parameter tells us that there are more rooms
+than returned in this request, and we need to make another request to get them.
+To get the next batch of room results, we repeat our request, setting the `from`
+parameter to the value of `next_token`.
+
+```
+GET /_synapse/admin/rooms?order_by=size&from=100
+
+{}
+```
+
+Response:
+
+```
+{
+  "rooms": [
+    {
+      "room_id": "!mscvqgqpHYjBGDxNym:matrix.org",
+      "name": "Music Theory",
+      "canonical_alias": "#musictheory:matrix.org",
+      "joined_members": 127
+    },
+    ... (48 hidden items) ...
+    {
+      "room_id": "!twcBhHVdZlQWuuxBhN:termina.org.uk",
+      "name": "weechat-matrix",
+      "canonical_alias": "#weechat-matrix:termina.org.uk",
+      "joined_members": 137
+    }
+  ],
+  "offset": 100,
+  "prev_batch": 0,
+  "total_rooms": 150
+}
+```
+
+Once the `next_token` parameter is no longer present, we know we've reached the
+end of the list.
