File operations 

Retrieve all files 

GET /api/files

Retrieve information regarding all files currently available and regarding the disk space still available locally in the system. The results are cached for performance reasons. If you want to override the cache, supply the query parameter force and set it to true. Note that while printing a refresh/override of the cache for files stored on the printer’s SD card is disabled due to bandwidth restrictions on the serial interface.

By default only returns the files and folders in the root directory. If the query parameter recursive is provided and set to true, returns all files and folders.

Returns a Retrieve response.

Requires the FILES_LIST permission.

Example 1:

Fetch only the files and folders from the root folder.

Retrieve files from specific location 

GET /api/files/(string: location)

Retrieve information regarding the files currently available on the selected location and – if targeting the local location – regarding the disk space still available locally in the system. The results are cached for performance reasons. If you want to override the cache, supply the query parameter force and set it to true. Note that while printing a refresh/override of the cache for files stored on the printer’s SD card is disabled due to bandwidth restrictions on the serial interface.

By default only returns the files and folders in the root directory. If the query parameter recursive is provided and set to true, returns all files and folders.

Returns a Retrieve response.

Parameters:

location – The origin location from which to retrieve the files. Currently only local and sdcard are supported, with local referring to files stored in OctoPrint’s uploads folder and sdcard referring to files stored on the printer’s SD card (if available).
force – If set to true, forces a refresh, overriding the cache.
recursive – If set to true, return all files and folders recursively. Otherwise only return items on same level.

Status Codes:

200 OK – No error
404 Not Found – If location is neither local nor sdcard

Upload file or create folder 

POST /api/files/(string: location)

Upload a file to the selected location or create a new empty folder on it.

Other than most of the other requests on OctoPrint’s API which are expected as JSON, this request is expected as Content-Type: multipart/form-data due to the included file upload. A Content-Length header specifying the full length of the request body is required as well.

To upload a file, the request body must at least contain the file form field with the contents and file name of the file to upload.

To create a new folder, the request body must at least contain the foldername form field, specifying the name of the new folder. Note that folder creation is currently only supported on the local file system.

Returns a 201 Created response with a Location header set to the management URL of the uploaded file and an Upload Response as the body upon successful completion.

Requires the FILES_UPLOAD permission.

    "origin": "local"
  },
  "done": true
}

Parameters:

location – The target location to which to upload the file. Currently only local and sdcard are supported here, with local referring to OctoPrint’s uploads folder and sdcard referring to the printer’s SD card. If an upload targets the SD card, it will also be stored locally first.

Form Parameters:

file – The file to upload, including a valid filename.
path – The path within the location to upload the file to or create the folder in (without the future filename or foldername - basically the parent folder). If unset will be taken from the provided file’s name or foldername and default to the root folder of the location.
select – Whether to select the file directly after upload (true) or not (false). Optional, defaults to false. If the printer is not operational, this will have no effect and the effectiveSelect field in the response will be set to false. Ignored when creating a folder.
print – Whether to start printing the file directly after upload (true) or not (false). If set, select is implicitly true as well. Optional, defaults to false. If the printer is not operational, this will have no effect and the effectivePrint field in the response will be set to false. Ignored when creating a folder.
userdata – [Optional] An optional string that if specified will be interpreted as JSON and then saved along with the file as metadata (metadata key userdata). Ignored when creating a folder.
foldername – The name of the folder to create. Ignored when uploading a file.

Status Codes:

201 Created – No error
400 Bad Request – If no file or foldername are included in the request, userdata was provided but could not be parsed as JSON or the request is otherwise invalid.
404 Not Found – If location is neither local nor sdcard or trying to upload to SD card and SD card support is disabled
409 Conflict – If the upload of the file would override the file that is currently being printed or if an upload to SD card was requested and the printer is either not operational or currently busy with a print job.
415 Unsupported Media Type – If the file is neither a gcode nor an stl file (or it is an stl file but slicing support is disabled)
500 Internal Server Error – If the upload failed internally

Retrieve a specific file’s or folder’s information 

GET /api/files/(string: location)/(path: filename)

Retrieves the selected file’s or folder’s information.

If the file is unknown, a 404 Not Found is returned.

If the targeted path is a folder, by default only its direct children will be returned. If recursive is provided and set to true, all sub folders and their children will be returned too.

On success, a 200 OK is returned, with a file information item as the response body.

Requires the FILES_LIST permission.

Issue a file command 

POST /api/files/(string: location)/(path: path)

Issue a file command to an existing file. Currently supported commands are:

select

Selects a file for printing. Additional parameters are:

print: Optional, if set to true the file will start printing directly after selection. If the printer is not operational when this parameter is present and set to true, the request will fail with a response of 409 Conflict.

Upon success, a status code of 204 No Content and an empty body is returned. If there already is an active print job, a 409 Conflict is returned.

Requires the FILES_SELECT permission.

unselect

Unselects the currently selected file for printing.

Upon success, a status code of 204 No Content and an empty body is returned. If no file is selected or there already is an active print job, a 409 Conflict is returned. If path isn’t current` or the filename of the current selection, a 400 Bad Request is returned

Requires the FILES_SELECT permission.

slice

Slices an STL file into GCODE. Note that this is an asynchronous operation that will take place in the background after the response has been sent back to the client. Additional parameters are:

slicer: The slicing engine to use, defaults to cura if not set, which is also the only supported slicer right now.
gcode: Name of the GCODE file to generated, in the same location as the STL file. Defaults to the STL file name with extension .gco if not set.
position: Position of the object-to-slice’s center on the print bed. A dictionary containing both x and y coordinate in mm is expected
printerProfile: Name of the printer profile to use, if not set the default printer profile will be used.
profile: Name of the slicing profile to use, if not set the default slicing profile of the slicer will be used.
profile.*: Override parameters, the profile. prefix will be stripped and the matching profile key will be overridden with the supplied value. Use this if you want to specify things that change often like a different temperature, filament diameter or infill percentage. Profile keys are slicer specific.
select: Optional, if set to true the file be selected for printing right after the slicing has finished. If the printer is not operational or already printing when this parameter is present and set to true, the request will fail with a response of 409 Conflict
print: Optional, if set to true the file be selected and start printing right after the slicing has finished. If the printer is not operational or already printing when this parameter is present and set to true, the request will fail with a response of 409 Conflict. Note that if this parameter is set, the parameter select does not need to be set, it is automatically assumed to be true too, otherwise no printing would be possible.

If consecutive slicing calls are made targeting the same GCODE filename (that also holds true if the default is used), the slicing job already running in the background will be cancelled before the new one is started. Note that this will also mean that if it was supposed to be directly selected and start printing after the slicing finished, this will not take place anymore and whether this will happen with the new sliced file depends entirely on the new request!

Upon success, a status code of 202 Accepted and a Abridged file or folder information in the response body will be returned.

Requires the SLICE permission.

copy

Copies the file or folder to a new destination on the same location. Additional parameters are:

destination: The path of the parent folder to which to copy the file or folder. It must already exist.

If there already exists a file or folder of the same name at destination, the request will return a 409 Conflict. If the destination folder does not exist, a 404 Not Found will be returned.

Upon success, a status code of 201 Created and a Abridged file or folder information in the response body will be returned.

Requires the FILES_UPLOAD permission.

move

Moves the file or folder to a new destination on the same location. Additional parameters are:

destination: The path of the parent folder to which to move the file or folder.

If there already exists a file or folder of the same name at destination, the request will return a 409 Conflict. If the destination folder does not exist, a 404 Not Found will be returned. If the path is currently in use by OctoPrint (e.g. it is a GCODE file that’s currently being printed) a 409 Conflict will be returned.

Upon success, a status code of 201 Created and a Abridged file or folder information in the response body will be returned.

Requires the FILES_UPLOAD permission.

slicer (string) – slice command: The slicer to use, defaults to the default slicer.
gcode (string) – slice command: The name of the gcode file to create, defaults to the targeted stl’s file name with its extension changed to .gco (e.g. “test.stl” will be sliced to “test.gco” if not specified otherwise)
profile (string) – slice command: The slicing profile to use, defaults to the selected slicer’s default profile.
profile.* (string) – slice command: Overrides for the selected slicing profile, e.g. to specify a different temperature or filament diameter.
printerProfile (string) – slice command: The printer profile to use, defaults to the default printer profile.

Data model 

Retrieve response 

Name	Multiplicity	Type	Description
`files`	0..*	Array of File information items	The list of requested files. Might be an empty list if no files are available
`free`	0..1	String	The amount of disk space in bytes available in the local disk space (refers to OctoPrint’s `uploads` folder). Only returned if file list was requested for origin `local` or all origins.

Upload response 

Name	Multiplicity	Type	Description
`files`	0..1	Object	(File only) Abridged information regarding the file that was just uploaded. If only uploaded to `local` this will only contain the `local` property. If uploaded to SD card, this will contain both `local` and `sdcard` properties.
`files.local`	1	Abridged file or folder information	The information regarding the file that was just uploaded to the local storage.
`files.sdcard`	0..1	Abridged file or folder information	The information regarding the file that was just uploaded to the printer’s SD card.
`folder`	0..1	Abridged file or folder information	(Folder only) Abridged information regarding the folder that was just created.
`done`	1	Boolean	Whether any file processing after upload has already finished (`true`) or not, e.g. due to first needing to perform a slicing step (`false`). Clients may use this information to direct progress displays related to the upload. Always `true` for folders.
`effectiveSelect`	0..1	Boolean	(File only) Whether the file that was just uploaded was selected for printing (`true`) or not (`false`). If this is `false` but was requested to be `true` in the upload request, the user lacked permissions, the printer was not operational or already printing and thus the request could not be fulfilled.
`effectivePrint`	0..1	Boolean	(File only) Whether the file that was just uploaded was started to print (`true`) or not (`false`). If this is `false` but was requested to be `true` in the upload request, the user lacked permissions, the printer was not operational or already printing and thus the request could not be fulfilled.
