The REST Interface gives you access to your RT Database. The complete communication is encapsulated in the HTTP protocol. The interface should be accessible in your installation.

Though you may see references to older 3.x releases of RT below, the REST 1.0 interface has not changed in any significant way in 4.x.

This page is for REST version 1.0. The next version of the RT REST interface, version 2.0, is available as an extension.

Legacy Comments are available from the previous Wikia instance.


Base URL: .../REST/1.0/. The default response should be:

   RT/3.4.5 200 Ok
   # Invalid object specification: 'index.html'
   id: index.html


The REST Interface does not support HTTP-Authentication. So you must get a valid Session-Token and submit the cookie each request. You usually get a Session-Cookie by submitting the default login form. Use variables "user" for login and "pass" for password values. wget doesn't escape any characters in the --post-data option so make sure you properly escape any special characters in the password.

See the wget invocation line below:

   wget  --keep-session-cookies \
   --save-cookies cookies.txt \
   --post-data 'user=UUUU&pass=PPPP' \

You need the -keep-session-cookies option to make wget save session cookies.


Ticket Properties

Gets the data for a single ticket, not including the history and comments.

Request: /REST/1.0/ticket/<ticket-id>/show

RT/3.4.5 200 Ok

id: ticket/<ticket-id>

Ticket Links

Gets the ticket links for a single ticket.

Request: REST/1.0/ticket/<ticket-id>/links/show

RT/3.8.2 200 Ok

id: ticket/<ticket-id>/links

Ticket Attachments

Gets a list of all attachments related to the ticket

Request: /REST/1.0/ticket/<ticket-id>/attachments

Ticket Attachment

Gets the metadata and content of a specific attachment.

Request: /REST/1.0/ticket/<ticket-id>/attachments/<attachment-id>

RT/3.8.0 200 Ok
id: <attachment-id>
Creator: <user-id>
Created: <timestamp>
Transaction: <transaction-id>
Parent: <parent-id>
Filename: <filename>
ContentType: application/octet-stream
ContentEncoding: none
Headers: MIME-Version: 1.0
         X-Mailer: MIME-tools 5.427 (Entity 5.427)
         Content-Type: application/octet-stream;
         Content-Disposition: inline; filename="<filename>"
         Content-Transfer-Encoding: base64
         Content-Length: <length in bytes>

Content: ...

NOTE: RT returns the content indented with 9 spaces on each line, so that it lines up with the "Content:" header. Even if you strip this out with a regexp, the content is still UTF-8, which is probably not what you want. To get the original binary data back, strip out the 9 spaces with a regexp, strip off the 3 carriage returns at the end, and then convert the whole thing from UTF-8 to the native character encoding of the attachment, whatever that is. RT doesn't tell you, so you have know. If the attachments were uploaded by a U.S. Windows system, odds are that Windows-1252 is what you want. If you can't get the binary back intact, see the next method below.

Ticket Attachment Content

Gets the attachment data content without additional metadata or whitespace characters

Request: /REST/1.0/ticket/<ticket-id>/attachments/<attachment-id>/content

RT/3.8.0 200 Ok


So to get the original content you still have to strip the first 2 lines of the response.

Ticket History

Gets a list of all the history items for a given ticket.

Request: /REST/1.0/ticket/<ticket-id>/history

RT/3.4.5 200 Ok

# <history-count>/<history-count> (/total)

<history-id>: <history-name>
<history-id>: <history-name>

You will get an additional row, for each history entry found. The first entry is usually: "Ticket created by ...".

There are two ways to get history item detail: you can do one of these and then recursively perform ticket/history/id/<history-id> for each history-id from this REST call, but that is extremely wasteful and will scale horribly. What you really want to do is one REST call but get the long format:

Request: /REST/1.0/ticket/<ticket-id>/history?format=l

RT/3.8.2 200 Ok

# <n>/<n> (id/<history-id>/total)

id: <history-id>
Ticket: <ticket-id>
TimeTaken: <...>
Type: <...>
Field: <...>
OldValue: <...>
NewValue: <...>
Data: <...>
Description: <...>
Content: <...>
Creator: <...>

Created: <...>

             <attachment-id>: <filename> (<size>)
             <attachment-id>: <filename> (<size>)


# <n>/<n> (id/<history-id>/total)

NOTE: the double dash "--" will occur in the long format between each history item. You can split the output on "--" and iterate over it, parsing out the data with an RFC822 parser, such as an email handling library.

Ticket History Entry

Gets the history information for a single history item. Note that the history item must actually correspond to the ticket.

Request: /REST/1.0/ticket/<ticket-id>/history/id/<history-id>

RT/3.4.5 200 Ok

# 70/70 (id/114856/total)

id: <history-id>
Ticket: <ticket-id>
TimeTaken: <...>
Type: <...>
Field: <...>
OldValue: <...>
NewValue: <...>
Data: <...>
Description: <...>

Content: <lin1-0>
Creator: <...>
Created: <...>
Attachments: <...>

IMPORTANT NOTE: At least with RT 3.8.0, when you request a history item with this method AND you have attached a file that has Mime type text/plain to the same item (eg. a comment with an attachement), RT will return the complete content of the attachment for the key "Content:" and not your real comment that you can see in the web frontend. This may lead to some problems if the requestor does not expect to get a comment content that is for example 1.8 MB of text. With other Mime type attachments this however seems to work. I don't know if this is a feature or a bug.

Ticket Search

Request: /REST/1.0/search/ticket?query=<query>&orderby=<sort-order>&format=<format>



You can use any query generated by the query builder - or feel free to write your own. Here an example that will do the following: Find all tickets that have no owner and the status new or open

query= Owner = 'Nobody' AND ( Status = 'new' OR Status = 'open' )

Example: to get all the tickets in "fooQueue" you'd access:


Example: to get the tickets for a custom field "Contact Name" you'd access:

/REST/1.0/search/ticket?query='CF.{Contact Name}'='Shaun Wallace'


By this parameter you can change the sort field and order of the search result. To sort a list ascending just put a + before the fieldname, otherwise a -. Eg: -Created (will put the newest tickets at the beginning).




  • i: ticket/<ticket-id>
  • s: <ticket-id>: <ticket-subject>
  • l: a multi-line format (Full ticket details without content)




A list of fields you would like included in the result set.



Note that you may need to escape characters like the curly braces for CFs.

Ticket Create

To create a new ticket: post on /REST/1.0/ticket/new with a variable named "content",

containing "key: value" line by line, example:

Testing the new ticket section

id: ticket/new
Queue: <queue name>
Requestor: <requestor email address>
Subject: <subject>
Cc: <...>
AdminCc: <...>
Owner: <...>
Status: <...>
Priority: <...>
InitialPriority: <...>
FinalPriority: <...>
TimeEstimated: <...>
Starts: <...>
Due: <...>
Text: <The ticket content>
CF-<CustomFieldName>: <CustomFieldValue>

If there are any "special" characters (Umlauts, dash, ...?) in a custom field's name, you can still access it via its ID:


If you want to have a multiline Text, prefix every line with a blank.

Due: <...>
Text: This is 
 multiline Text
CF-<CustomFieldName>: <CustomFieldValue>

The response should look like:

RT/4.0.6 200 Ok

# Ticket 775 created.
curl example
 * Create a file containing the ticket form:
id: ticket/new
Queue: queue1
Requestor: requestor@email
Priority: 4
CF-Type of request: Demande
Subject: Test REST
Text: Multi line
 test with
 special chars: é
 * Submit using curl:
curl --data-urlencode 'https://HOSTNAME/REST/1.0/ticket/new?user=USER&pass=PASSWORD'

Ticket Edit

To update an existing ticket: post on /REST/1.0/ticket/<ticket-id>/edit with a variable named "content", containing "key: value" line by line (like the one displayed when issuing ticket/<ticket-id>/show). Example:

Priority: 5
TimeWorked: 15
  • PHP
$username = rt_user;
$password = rt_pass;
$url = "http://server.domain.tld/REST/1.0/ticket/<ticket id>/edit?user=$username&pass=$password";

$request = new HttpRequest($url, HTTP_METH_POST);
$post_data=array("content"=>"AdminCc: userX\nText: This is a REST test edit ticket\n");

// add the post fields  

// response from RT
$response = $request->send()->getBody();

Tickets History Reply

Same as comment: post on /REST/1.0/ticket/<ticket-id>/comment with a variable name content, containing "key: value" line by line:

id: <ticket-id>
Action: correspond
Text: the text comment
Cc: <...>
Bcc: <...>
TimeWorked: <...>
Attachment: an attachment filename/path

Cc and Bcc are for this reply only (I think).

Ticket History Comment

To add a comment to an existing ticket: POST on "/REST/1.0/ticket/<ticket-id>/comment" with a variable name "content", containing "key: value" line by line:

id: <ticket-id>
Action: comment
Text: the text comment
Attachment: an attachment filename/path

Action can be "comment" or "correspond". For a list of fields you can use in correspondence, try "/opt/rt3/bin/rt correspond ticket/1"

If your comment contains multiple lines, each new line must be preceded by a space (e.g. "line 1\n line 2").

If you want to use HTML replies, use

Content-Type: text/html

If you used "Attachment", you must add to your POST a variable "attachment_1" that contains the raw attachment in multi-part file object.

You can upload more attachments as well, in this case you have to separate the file names in the "Attachment" with "\n "(a newline and space, without quotes) and add a new variable "attachment_$i" to your POST where $i is the index of attachment.

You need to send header to post comments

Ticket Links Edit

To update links on an existing ticket: POST on "/REST/1.0/ticket/<ticket-id>/links" with a variable named "content", containing "key: value" line by line (like the one displayed when issuing "ticket/<ticket-id>/links"). Example:

DependsOn: 54354
RefersTo: http://some.external/link

Ticket Merge

To merge tickets: POST on "/REST/1.0/ticket/<origin-ticket-id>/merge/<into-ticket-id>". (I don't think any content is required, but I send "id" and "into" anyway.)

User Properties

Gets the data for a single user.

Request: /REST/1.0/user/<user-id>

RT/3.8.4 200 Ok

id: user/<user-id>
Name: <...>
Password: ********
EmailAddress: <...>
RealName: <...>
Organization: <...>
Privileged: <...>
Disabled: <...>

Also you can use user login instead of user ID.


User Create

To create a new user: post on /REST/1.0/user/new with a variable named "content", containing "key: value" line by line, like the response to /user/<ticket-id>

User Edit

To update an existing user: post on /REST/1.0/user/<user-id>/edit with a variable named "content", containing "key: value" line by line (like the one displayed when issuing user/<user-id>/show).


Search for all queues mail addresses like thist:


Single queue properties

  • Use only "\n", not "\r\n"in post content.
  • Comments in response body starts with with a hash (#) symbol.

Request status

To get real request/post status you need to check status code in first line of server response.



To get the results of a single request (without setting the Session-Cookie) - assuming you've set:

  • $uri to your RT REST URL
  • $access_user to your username
  • $access_password to your password
  • $ticketNumber to the ticket you want to see
my $ua = LWP::UserAgent->new;
my $response = $ua->post($uri."ticket/$ticketNumber",
   ['user' => $access_user, 'pass' => $access_password],
    'Content_Type' => 'form-data');

if ($response->is_success) {
   print $response->decoded_content;

This is an example of updating the RefersTo field for a ticket. Assuming Zepto/jQuery is also being used.

function link_back(url, ticket_num, rt) {

    data = {"content": link};

var url = "";
var ticket_num = "123456";
var rt = "https://some.rt.url/REST/1.0/ticket/";

link_back(url, ticket_num, rt);
