+# List of supported HTTP requests
+
+RepRapFirmware provides an HTTP interface for dealing with client requests.
+These requests are tailored for Duet Web Control in the first place but they may be used by third-party applications, too.
+
+Every request except for `rr_connect` returns HTTP status code `401` if the client does not have a valid session.
+If no machine password is set, a user session is created whenever an arbitrary HTTP request is made.
+Besides, RepRapFirmware may run short on memory and may not be able to respond properly. In this case, HTTP status code `503` is returned.
+
+In the following requests datetime strings may be used. These datetime strings are very similar to ISO8601-encoded strings but they do not contain timezone details.
+An example for such a string is `2019-12-13T21:27:00`. Make sure to follow this format where applicable.
+
+## GET /rr_connect
+
+Attempt to create a new connection and log in using the (optional) password.
+
+Supported parameters:
+
+- `password` (optional): Machine password to log in with. If omitted, this defaults to `reprap`
+- `time` (optional): Current datetime that will be used to update RepRapFirmware's internal clock
+
+Returns
+
+```
+{
+    "err": code
+}
+```
+
+where `code` may be one of the following:
+
+- `0`: Password is valid and the client's IP address is added to the list of HTTP sessions
+- `1`: Password is invalid
+- `2`: No more user sessions available. This may occur when too many client devices are connected at the same time
+
+If the password is valid, extra fields are returned:
+
+```
+{
+    "err": 0,
+    "sessionTimeout": 8000,
+    "boardType": "duetwifi102"
+}
+```
+
+- `sessionTimeout` is the idle timeout in milliseconds before a client is removed again from the list of client sessions
+- `boardType` represents the board's type
+
+Officially supported board types are:
+
+| boardType | Board | Remarks |
+| --------- | ----- | ------- |
+| duet06 | Duet 0.6 | deprecated |
+| duet07 | Duet 0.7 | deprecated |
+| duet085 | Duet 0.8.5 | deprecated |
+| duetwifi10 | Duet WiFi v1.0 ||
+| duetwifi102 | Duet WiFi v1.02 ||
+| duetethernet10 | Duet Ethernet v1.0 ||
+| duetethernet102 | Duet Ethernet v1.02 ||
+| duetmaestro100 | Duet Maestro v1.0 ||
+| duet3mb6hc | Duet 3 v0.6 ||
+
+## GET /rr_disconnect
+
+Disconnect again from the RepRapFirmware controller.
+
+Returns
+
+```
+{
+    "err": code
+}
+```
+
+where `code` may be `0` if the session could be removed, else it is `1`.
+
+## GET /rr_status
+
+Retrieve a status response from RepRapFirmware in JSON format.
+
+Supported parameters:
+
+- `type`: Type of the status response
+
+The value of `type` can be one of:
+
+- 1: Standard status response
+- 2: Advanced status response. This also contains fields from the standard status response
+- 3: Print status response. This contains fields from the standard status response as well as information about the current (print) job
+
+See [JSON responses](JSON%20Responses.md) for further information.
+
+## Get /rr_config
+
+Retrieve the configuration response. This request provides a JSON object with values that are expected to change rarely. 
+
+See [JSON responses](JSON%20Responses.md) for further information.
+
+## GET /rr__gcode
+
+Execute arbitrary G/M/T-code(s).
+
+Supported parameters:
+
+- `gcode`: G/M/T-code to execute. This parameter must be present although it can be empty
+
+Returns
+
+```
+{
+    "buff": bufferSpace
+}
+```
+
+where `bufferSpace` indicates how much buffer space for new G/M/T-codes is still available.
+
+If a file is supposed to be streamed over the HTTP interface, call this repeatedly and transfer only as many bytes as allowed.
+
+## GET /rr_reply
+
+Retrieve the last G-code reply. The G-code reply is buffered per connected HTTP client and it is discarded when every HTTP client has fetched it or
+when the firmware is short on memory and the client has not requested it within reasonable time (1 second).
+
+The G-code reply is returned as `text/plain`.
+
+## GET /rr_upload
+
+Get the last file upload result.
+
+Returns
+
+```
+{
+    "err": code
+}
+```
+
+where `code` can be either `0` if the last upload successfully finished or `1` if an error occurred.
+
+## POST /rr_upload
+
+Upload a file.
+
+Supported URL parameters:
+
+- `name`: Path to the file to upload
+- `time` (optional): ISO8601-like represenation of the time the file was last modified
+- `crc32` (optional): CRC32 checksum of the file content as hex string *without* leading `0x`. Usage of this parameter is encouraged
+
+The raw HTTP body contains the file content. Binary file uploads are supported as well.
+Make sure to set `Content-Length` to the length of the HTTP body if your HTTP client does not already do that.
+
+Returns
+
+```
+{
+    "err": code
+}
+```
+
+where `code` can be either `0` if the last upload successfully finished or `1` if an error occurred (e.g. CRC mismatch).
+
+## GET /rr_download
+
+Download a file.
+
+Supported parameters:
+
+- `name`: Filename to download
+
+If the file could not be found, HTTP status code 404 is returned, else the file content is sent to the client.
+
+## GET /rr_delete
+
+Delete a file or directory.
+
+Supported parameters:
+
+- `name`: Filename to delete
+
+Returns
+
+```
+{
+    "err": {code}
+}
+```
+
+where code is either `0` on success or `1` on error.
+
+## GET /rr_filelist
+
+Retrieve a (partial) file list.
+
+Supported parameters:
+
+- `dir`: Directory to query
+- `first` (optional): First item index to return. Defaults to `0`
+
+Returns
+```
+{
+    "dir": dir,
+    "first": first,
+    "files": [

+        },
+        ...
+    ],
+    "next": next,
+    "err": code
+}
+```
+
+where `dir` and `first` equal the query parameters. `err` can be one of:
+
+- `0`: List query successful
+- `1`: Drive is not mounted
+- `2`: Directory does not exist
+
+The `next` field may be omitted if the query was not successful and it is `0` if the query has finished. If there are more items to query, this value can be used for the `first` parameter of a successive `rr_filelist` request.
+
+Retrieved files are returned as part of the `files` array. Note that `date` may not be present if it is invalid. Every item has the following properties:
+
+- `itemType`: Type of the file item. This is `d` for directories and `f` for files

+
+where `dir` and `first` equal the query parameters. `err` can be one of:
+
+- `0`: List query successful
+- `1`: Drive is not mounted
+- `2`: Directory does not exist
+
+The `next` field may be omitted if the query was not successful and it is `0` if the query has finished. If there are more items to query, this value can be used for the `first` parameter of a successive `rr_files` request.
+
+## GET /rr_move

+
+Supported parameters:
+
+- `old`: Current path to the file or directory
