| 1 | 1. Introduction |
|---|
| 2 | |
|---|
| 3 | This document describes a protocol for interacting with Transmission |
|---|
| 4 | sessions remotely. |
|---|
| 5 | |
|---|
| 6 | 1.1 Terminology |
|---|
| 7 | |
|---|
| 8 | The JSON terminology in RFC 4627 is used. |
|---|
| 9 | |
|---|
| 10 | JSON is fairly common now, but for the benefit of |
|---|
| 11 | torrent developers familiar with benc: |
|---|
| 12 | a JSON array is equivalent to a benc list, |
|---|
| 13 | a JSON object is equivalent to a benc dictionary, |
|---|
| 14 | and a JSON object's keys are the dictionary's string keys. |
|---|
| 15 | |
|---|
| 16 | 1.2 Resources |
|---|
| 17 | |
|---|
| 18 | The command-line utility "transmission-remote" uses this RPC API. |
|---|
| 19 | Several developers have reported using its --debug JSON output as |
|---|
| 20 | a reference when developing/debugging their own code. |
|---|
| 21 | |
|---|
| 22 | 2. Message Format |
|---|
| 23 | |
|---|
| 24 | Messages are formatted as objects. There are two types: |
|---|
| 25 | requests (described in 2.1) and responses (described in 2.2). |
|---|
| 26 | |
|---|
| 27 | All text MUST be UTF-8 encoded. |
|---|
| 28 | |
|---|
| 29 | 2.1. Requests |
|---|
| 30 | |
|---|
| 31 | Requests support three keys: |
|---|
| 32 | |
|---|
| 33 | (1) A required "method" string telling the name of the method to invoke |
|---|
| 34 | (2) An optional "arguments" object of key/value pairs |
|---|
| 35 | (3) An optional "tag" number used by clients to track responses. |
|---|
| 36 | If provided by a request, the response MUST include the same tag. |
|---|
| 37 | |
|---|
| 38 | 2.2. Responses |
|---|
| 39 | |
|---|
| 40 | Reponses support three keys: |
|---|
| 41 | |
|---|
| 42 | (1) A required "result" string whose value MUST be "success" on success, |
|---|
| 43 | or an error string on failure. |
|---|
| 44 | (2) An optional "arguments" object of key/value pairs |
|---|
| 45 | (3) An optional "tag" number as described in 2.1. |
|---|
| 46 | |
|---|
| 47 | 2.3. Transport Mechanism |
|---|
| 48 | |
|---|
| 49 | HTTP POSTing a JSON-encoded request is the preferred way of communicating |
|---|
| 50 | with a Transmission RPC server. The current Transmission implementation |
|---|
| 51 | has the default URL as http://host:9091/transmission/rpc. Clients |
|---|
| 52 | may use this as a default, but should allow the URL to be reconfigured, |
|---|
| 53 | since the port and path may be changed to allow mapping and/or multiple |
|---|
| 54 | daemons to run on a single server. |
|---|
| 55 | |
|---|
| 56 | 2.3.1. CSRF Protection |
|---|
| 57 | |
|---|
| 58 | Most Transmission RPC servers require a X-Transmission-Session-Id |
|---|
| 59 | header to be sent with requests, to prevent CSRF attacks. |
|---|
| 60 | |
|---|
| 61 | When your request has the wrong id -- such as when you send your first |
|---|
| 62 | request, or when the server expires the CSRF token -- the |
|---|
| 63 | Transmission RPC server will return an HTTP 409 error with the |
|---|
| 64 | right X-Transmission-Session-Id in its own headers. |
|---|
| 65 | |
|---|
| 66 | So, the correct way to handle a 409 response is to update your |
|---|
| 67 | X-Transmission-Session-Id and to resend the previous request. |
|---|
| 68 | |
|---|
| 69 | 3. Torrent Requests |
|---|
| 70 | |
|---|
| 71 | 3.1. Torrent Action Requests |
|---|
| 72 | |
|---|

| 76 | "torrent-start-now" | tr_torrentStartNow |
|---|
| 77 | "torrent-stop" | tr_torrentStop |
|---|
| 78 | "torrent-verify" | tr_torrentVerify |
|---|
| 79 | "torrent-reannounce" | tr_torrentManualUpdate ("ask tracker for more peers") |
|---|
| 80 | |
|---|
| 81 | Request arguments: "ids", which specifies which torrents to use. |
|---|
| 82 | All torrents are used if the "ids" argument is omitted. |
|---|
| 83 | "ids" should be one of the following: |
|---|
| 84 | (1) an integer referring to a torrent id |
|---|
| 85 | (2) a list of torrent id numbers, sha1 hash strings, or both |
|---|
| 86 | (3) a string, "recently-active", for recently-active torrents |
|---|
| 87 | |
|---|
| 88 | Response arguments: none |
|---|
| 89 | |
|---|
| 90 | 3.2. Torrent Mutators |
|---|
| 91 | |
|---|
| 92 | Method name: "torrent-set" |
|---|
| 93 | |
|---|
| 94 | Request arguments: |
|---|
| 95 | |
|---|
| 96 | string | value type & description |
|---|
| 97 | ----------------------+------------------------------------------------- |
|---|
| 98 | "bandwidthPriority" | number this torrent's bandwidth tr_priority_t |
|---|

| 103 | "honorsSessionLimits" | boolean true if session upload limits are honored |
|---|
| 104 | "ids" | array torrent list, as described in 3.1 |
|---|
| 105 | "location" | string new location of the torrent's content |
|---|
| 106 | "peer-limit" | number maximum number of peers |
|---|
| 107 | "priority-high" | array indices of high-priority file(s) |
|---|
| 108 | "priority-low" | array indices of low-priority file(s) |
|---|
| 109 | "priority-normal" | array indices of normal-priority file(s) |
|---|
| 110 | "queuePosition" | number position of this torrent in its queue [0...n) |
|---|
| 111 | "seedIdleLimit" | number torrent-level number of minutes of seeding inactivity |
|---|
| 112 | "seedIdleMode" | number which seeding inactivity to use. See tr_idlelimit |
|---|
| 113 | "seedRatioLimit" | double torrent-level seeding ratio |

|---|
| 119 | "uploadLimited" | boolean true if "uploadLimit" is honored |
|---|
| 120 | |
|---|
| 121 | Just as an empty "ids" value is shorthand for "all ids", using an empty array |
|---|
| 122 | for "files-wanted", "files-unwanted", "priority-high", "priority-low", or |
|---|
| 123 | "priority-normal" is shorthand for saying "all files". |
|---|
| 124 | |
|---|
| 125 | Response arguments: none |
|---|
| 126 | |
|---|
| 127 | 3.3. Torrent Accessors |

| 769 | 5.1. Upcoming Breakage |
|---|
| 770 | |
|---|
| 771 | These features will be removed three months after 2.80's release: |
|---|
| 772 | |
|---|
| 773 | 1. session-get's 'download-dir-free-space' argument will be removed. |
|---|
| 774 | Its functionality has been superceded by the 'free-space' method. |
|---|
| 775 | |
|---|
| 776 | 2. HTTP POSTs to http://server:port/transmission/upload will fail. |
|---|
| 777 | This was an undocumented hack to allow web clients to add files without |
|---|
| 778 | client-side access to the file. This functionality is superceded by |
|---|
| 779 | using HTML5's FileReader object + the documented 'torrent-add' method. |
