Transmission's RPC specification

This document describes a protocol for interacting with Transmission sessions remotely.

1.1 Terminology

The JSON terminology in RFC 4627 is used. RPC requests and responses are formatted in JSON.

1.2 Tools

If transmission-remote is called with a --debug argument, its RPC traffic to the Transmission server will be dumped to the terminal. This can be useful when you want to compare requests in your application to another for reference.

If transmission-qt is run with an environment variable TR_RPC_VERBOSE set, it too will dump the RPC requests and responses to the terminal for inspection.

Lastly, using devtools in the Transmission web client is always an option.

2 Message format

Messages are formatted as objects. There are two types: requests (described in 2.1) and responses (described in 2.2).

All text must be UTF-8 encoded.

2.1 Requests

Requests support three keys:

  1. A required method string telling the name of the method to invoke
  2. An optional arguments object of key/value pairs. The keys allowed are defined by the method.
  3. An optional tag number used by clients to track responses. If provided by a request, the response MUST include the same tag.
{
   "arguments": {
     "fields": [
       "version"
     ]
   },
   "method": "session-get",
   "tag": 912313
}

2.2 Responses

Responses to a request will include:

  1. A required result string whose value MUST be success on success, or an error string on failure.
  2. An optional arguments object of key/value pairs. Its keys contents are defined by the method and arguments of the original request.
  3. An optional tag number as described in 2.1.
{
   "arguments": {
      "version": "2.93 (3c5870d4f5)"
   },
   "result": "success",
   "tag": 912313
}

2.3 Transport mechanism

HTTP POSTing a JSON-encoded request is the preferred way of communicating with a Transmission RPC server. The current Transmission implementation has the default URL as http://host:9091/transmission/rpc. Clients may use this as a default, but should allow the URL to be reconfigured, since the port and path may be changed to allow mapping and/or multiple daemons to run on a single server.

2.3.1 CSRF protection

Most Transmission RPC servers require a X-Transmission-Session-Id header to be sent with requests, to prevent CSRF attacks.

When your request has the wrong id -- such as when you send your first request, or when the server expires the CSRF token -- the Transmission RPC server will return an HTTP 409 error with the right X-Transmission-Session-Id in its own headers.

So, the correct way to handle a 409 response is to update your X-Transmission-Session-Id and to resend the previous request.

2.3.2 DNS rebinding protection

Additional check is being made on each RPC request to make sure that the client sending the request does so using one of the allowed hostnames by which RPC server is meant to be available.

If host whitelisting is enabled (which is true by default), Transmission inspects the Host: HTTP header value (with port stripped, if any) and matches it to one of the whitelisted names. Regardless of host whitelist content, localhost and localhost. domain names as well as all the IP addresses are always implicitly allowed.

For more information on configuration, see settings.json documentation for rpc-host-whitelist-enabled and rpc-host-whitelist keys.

2.3.3 Authentication

Enabling authentication is an optional security feature that can be enabled on Transmission RPC servers. Authentication occurs by method of HTTP Basic Access Authentication.

If authentication is enabled, Transmission inspects the Authorization: HTTP header value to validate the credentials of the request. The value of this HTTP header is expected to be Basic <b64 credentials>, where is equal to a base64 encoded string of the username and password (respectively), separated by a colon.

3 Torrent requests

3.1 Torrent action requests

Method name libtransmission function
torrent-start tr_torrentStart
torrent-start-now tr_torrentStartNow
torrent-stop tr_torrentStop
torrent-verify tr_torrentVerify
torrent-reannounce tr_torrentManualUpdate ("ask tracker for more peers")

Request arguments: ids, which specifies which torrents to use. All torrents are used if the ids argument is omitted.

ids should be one of the following:

  1. an integer referring to a torrent id
  2. a list of torrent id numbers, SHA1 hash strings, or both
  3. a string, recently-active, for recently-active torrents

Response arguments: none

3.2 Torrent mutator: torrent-set

Method name: torrent-set

Request arguments:

Key Value Type Value Description
bandwidthPriority number this torrent's bandwidth tr_priority_t
downloadLimit number maximum download speed (KBps)
downloadLimited boolean true if downloadLimit is honored
files-unwanted array indices of file(s) to not download
files-wanted array indices of file(s) to download
group string The name of this torrent's bandwidth group
honorsSessionLimits boolean true if session upload limits are honored
ids array torrent list, as described in 3.1
labels array array of string labels
location string new location of the torrent's content
peer-limit number maximum number of peers
priority-high array indices of high-priority file(s)
priority-low array indices of low-priority file(s)
priority-normal array indices of normal-priority file(s)
queuePosition number position of this torrent in its queue [0...n)
seedIdleLimit number torrent-level number of minutes of seeding inactivity
seedIdleMode number which seeding inactivity to use. See tr_idlelimit
seedRatioLimit double torrent-level seeding ratio
seedRatioMode number which ratio to use. See tr_ratiolimit
trackerAdd array DEPRECATED use trackerList instead
trackerList string string of announce URLs, one per line, with a blank line between tiers
trackerRemove array DEPRECATED use trackerList instead
trackerReplace array DEPRECATED use trackerList instead
uploadLimit number maximum upload speed (KBps)
uploadLimited boolean true if uploadLimit is honored

Just as an empty ids value is shorthand for "all ids", using an empty array for files-wanted, files-unwanted, priority-high, priority-low, or priority-normal is shorthand for saying "all files".

Response arguments: none

3.3 Torrent accessor: torrent-get

Method name: torrent-get.

Request arguments:

  1. An optional ids array as described in 3.1.
  2. A required fields array of keys. (see list below)
  3. An optional format string specifying how to format the torrents response field. Allowed values are objects (default) and table. (see "Response arguments" below)

Response arguments:

  1. A torrents array.

    If the format request was objects (default), torrents will be an array of objects, each of which contains the key/value pairs matching the request's fields arg. This was the only format before Transmission 3 and has some obvious programmer conveniences, such as parsing directly into Javascript objects.

    If the format was table, then torrents will be an array of arrays. The first row holds the keys and each remaining row holds a torrent's values for those keys. This format is more efficient in terms of JSON generation and JSON parsing.

  2. If the request's ids field was recently-active, a removed array of torrent-id numbers of recently-removed torrents.

Note: For more information on what these fields mean, see the comments in libtransmission/transmission.h. The 'source' column here corresponds to the data structure there.

rpc-version indicates the RPC interface version supported by the RPC server. It is incremented when a new version of Transmission changes the RPC interface.

rpc-version-minimum indicates the oldest API supported by the RPC server. It is changes when a new version of Transmission changes the RPC interface in a way that is not backwards compatible. There are no plans for this to be common behavior.

5 Protocol versions

This section lists the changes that have been made to the RPC protocol.

There are two ways to check for API compatibility. Since most developers know semver, session-get's rpc-version-semver is the recommended way. That value is a semver-compatible string of the RPC protocol version number.

Since Transmission predates the semver 1.0 spec, the previous scheme was for the RPC version to be a whole number and to increment it whenever a change was made. That is session-get's rpc-version. rpc-version-minimum lists the oldest version that is compatible with the current version; i.e. an app coded to use rpc-version-minimum would still work on a Transmission release running rpc-version.

Breaking changes are denoted with a 💣 emoji.
