Authorization requires using Authorization header inside GET/POST requests. qBittorrent uses the standard Digest Authorization type (using a MD5 hash generator).

For example on Python using requests:

import requests
from requests.auth import HTTPDigestAuth

response = requests.post('http://127.0.0.1:8080/command/download', {'urls': magnet_link}, auth=HTTPDigestAuth(username, password))
if not response.ok:
    response.raise_for_status()
response.content

1. Digest Authorization standard

This page describes how this auth method should ideally work. The most important thing there is response field generation. Response is generated like this: MD5 ( A1 + ':' + nonce + ':' + A2 ) where
A1 is MD5 (username + ':' + realm + ':' + password)
A2 is MD5 (<method type string (e.g. GET or POST)> + ':' + uri)

1. Server Auth response

When you fail Authorization or don't supply required header qBittorrent will send the following reply (example):

HTTP/1.1 401 Unauthorized
WWW-Authenticate: Digest realm="Web UI Access", nonce="a3f396f2dcc1cafae73637e2ac321134", opaque="a3f396f2dcc1cafae73637e2ac321134", stale="false", algorithm="MD5", qop="auth"

nonce and opaque values will be random, nevertheless it looks like matching them is not required for successful authorization - qBittorrent doesn't track user session.

1. Client Auth request

We will now generate our request to the server containing proper Authorization header based on the example above.

1. User-Agent

   You can place whatever you want as user agent, it is not required anyway.
   User-Agent: Fiddler

2. Host

   Server address or domain name.
   Host: 127.0.0.1

3. Authorization

   This header is required.
   

Authorization: Digest username="admin", realm="Web UI Access", nonce="a3f396f2dcc1cafae73637e2ac321134", uri="/", response="4067cfe4c029cd00b56076c78abd034c" ```

  All fields in this header are required. Since `nonce` is not tracked by qBittorrent you should MD5-generate it yourself either one-time or each time you do any request. `uri` is not checked, if you want to GET host/someurl and `uri` doesn't match this value - no problem, just remember that `uri` is used in `response` generation.

  In Short: **You don't need a previous server reply in order to generate a proper request.**

  You must supply Authorization header in any POST/GET request you issue.

1. End Result

   Server reply:

HTTP/1.1 401 Unauthorized WWW-Authenticate: Digest realm="Web UI Access", nonce="a3f396f2dcc1cafae73637e2ac321134", opaque="a3f396f2dcc1cafae73637e2ac321134", stale="false", algorithm="MD5", qop="auth" ```

Proper suffix is appended automatically by qBt.

progress - float number for download completion percentage, where 1 == 100%, 0 == 0%, and, 0.58 == 58%
dlspeed and upspeed: torrent download and upload speed respectively, possible values:

1. Unknown - qBt couldn't determine torrent speed for some reason
2. X suffix/s - X B/KiB/MiB/GiB/TiB

priority - torrent number in priority queue; contains * if queuing is disabled or torrent is in seed mode
num_seeds and num_leechs - number of peers and lecchers
ratio - Uploaded/Downloaded ratio, rounded to first digit after comma; contains ∞ if ratio > 100
eta - contains ∞ if torrent is seeding only or eta >= 8640000 seconds; possible values:

1. 0 - zero
2. < 1m - less than a minute
3. MMm - MM minutes
4. HHh MMm - HH hours and MM minutes
5. DDd HHh - DD days and HH hours

DD/HH/MM values can be truncated if first digit is zero

state - torrent state, possible values:

1. error - some error occurred, applies to paused torrents
2. pausedUP - torrent is paused and has finished downloading
3. pausedDL - torrent is paused and has NOT finished downloading
4. queuedUP - queuing is enabled and torrent is queued for upload
5. queuedDL - queuing is enabled and torrent is queued for download
6. uploading - torrent is being seeded and data is being transferred
7. stalledUP - torrent is being seeded, but no connection were made
8. checkingUP - torrent has finished downloading and is being checked; this status also applies to preallocation (if enabled) and checking resume data on qBt startup
9. checkingDL - same as checkingUP, but torrent has NOT finished downloading
10. downloading - torrent is being downloaded and data is being transferred
11. stalledDL - torrent is being downloaded, but no connection were made

BIG FAT WARNING: size, dlspeed, upspeed and eta suffixes (e.g. MiB, KiB/s) will depend on current language selected in qBt; these suffixes will be translated.

BIG FAT WARNING 2: Raw data this methods provides can exceed 40 KiB for ~200 torrents. Continuous polling is strongly discouraged for mobile clients.

1. There is no need to pass all possible preferences' token:value pairs if you only want to change one option
2. When setting preferences scan_dirs must always be accompanied with download_in_scan_dirs
3. Paths in scan_dirs must exist, otherwise this option will have no effect
4. String values must be quoted; integer and boolean values must never be quoted

For a list of possible preference options see Get qBittorrent preferences

The following WebUI-related bugs exist in qBittorent v3.0.8 and lower:

1. JSON generation bugs

• ' and & (apostrophe and ampersand) characters are escaped by backslash \

1. JSON parsing bugs

• When setting qBittorent preferences JSON values, containing : semicolons will be disregarded; this mostly affects Windows users, whose paths start with DiskName:\
• When setting qBittorent preferences JSON bool lists (e.g. "download_in_scan_dirs":[false,true]) will be treated as all bool values in the list are false, this doesn't affect bool values outside JSON lists
