This documentation is not meant to be comprehensive, but just provide some initial knowledge useful for using the API.

You can start by opening http://teamcity:8111/httpAuth/app/rest URL in your browser: this page will give you several pointers to explorer the API.

Use http://teamcity:8111/httpAuth/app/rest/application.wadl to get the full list of supported requests and names of parameters. This is the primary source of discovery for the supported requests and their parameters.

You can start with http://teamcity:8111/httpAuth/app/rest/server request and then drill down following "href" attributes of the entities listed.
Please make sure you read through this "General information" section before using the API.

...

...

Note: If the value contains the "," symbol, it should be enclosed into parentheses: "(<value>)". The value of a dimension can also be encoded as Base64url and sent as "<dimension>:($base64:<base64-encoded-value >)" instead of " <dimension>: <value>".

Examples

http://teamcity:8111/httpAuth/app/rest/projects gets you the list of projects
http://teamcity:8111/httpAuth/app/rest/projects/<projectsLocator> - http://teamcity:8111/httpAuth/app/rest/projects/id:RESTAPIPlugin (the example id is used) gets you the full data for the REST API Plugin project.
http://teamcity:8111/httpAuth/app/rest/buildTypes/id:bt284/builds?locator=<buildLocator> - http://teamcity:8111/httpAuth/app/rest/buildTypes/id:bt284/builds?locator=status:SUCCESS,tag:EAP - (example ids are used) to get builds
http://teamcity:8111/httpAuth/app/rest/builds/?locator=<buildLocator> - to get builds by build locator.

Supported HTTP Methods

  • GET: retrieves the requested data
  • POST: creates the entity in the request adding it to the existing collection. When posting XML, be sure to specify the "Content-Type: application/xml" HTTP header.
  • PUT: based on the existence of the entity, creates or updates the entity in the request
  • DELETE: removes the requested data

...

To enable support for preflight OPTIONS request, add "rest.cors.optionsRequest.allowUnauthorized=true" internal property, restart the server and use "/app/rest/latest" URL for the requests (not "/app/rest", without "httpAuth" prefix).

If that does not help, enable debug logging and look for related messages. If there are none, capture the browser traffic and messages to investigate the case.

Anchor
vcs_root_instances
vcs_root_instances
List VCS root instances: GET http://teamcity:8111/httpAuth/app/rest/vcs-root-instances?locator=<vcsRootInstancesLocator>
A "VCS root" is the setting configured in the TeamCity UI, "VCS root instance" is the internal TeamCity entity which is derived from the "VCS root" to perform actual VCS operation.
If the VCS root has no %-references to parameters, a single VCS root corresponds to a single "VCS root instance".
If a VCS root has %-reference to a parameter and the reference resolves to a different value when the VCS root is attached to different configurations or when custom builds are run, a single "VCS root" can generate several "VCS root instances".

...

There are two endpoints dedicated at using in commit hooks from the version control repositories:
POST  http://teamcity:8111/app/rest/vcs-root-instances/checkingForChangesQueue?locator=<vcsRootInstancesLocator> - schedules checking for changes for the matched VCS root instances and returns the list of VCS root instances matched (just like GET http://teamcity:8111/httpAuth/app/rest/vcs-root-instances?locator=<vcsRootInstancesLocator> )
POST  http://teamcity:8111/app/rest/vcs-root-instances/commitHookNotification?locator=<vcsRootInstancesLocator> - schedules checking for changes for the matched VCS root instances and returns plain-text human-readable message on the action performed, HTTP response 202 in case of successful operation
Both perform the same action (put the VCS root instances matched by the <locator>) to the queue for "checking for changes" process and differ only in responses they produce.
Note that since the matched VCS root instances are the same as for .../app/rest/vcs-root-instances?locator=<locator> request and that means that by default only the first 100 are matched and the rest are ignored. If this limit is hit consider tweaking the <locator> to match less instances (recommended) or increase the limit e.g. by adding ",count:1000" to the locator.

Build Locator

Using a locator in build-related requests, you can filter the builds to be returned in the build-related requests. It is referred to as "build locator" in the scope of REST API.

...

Anchor
branchLocator
branchLocator
branch:<branch locator> - limit the builds by branch. <branch locator> can be the branch name displayed in the UI, or "(name:<name>,default:<true/false/any>,unspecified:<true/false/any>,branched:<true/false/any>)". By default only builds from the default branch are returned. To retrieve all builds, add the following locator: branch:default:any. The whole path will look like this: /httpAuthhttpAuthpp/app/rest/builds/?locator=buildType:One_Git,branch:default:any

revision:<REVISION> - find builds by revision, e.g. all builds of the given build configuration with the revision: /httpAuth/app/rest/builds?locator=revision:(REVISION),buildType:(id:BUILD_TYPE_ID). See more information below.
agentName:<name> - agent name to return only builds ran on the agent with name specified

Wiki Markup
{hidden-data}
Since *TeamCity 9.1*:
"locator" parameter is supported for the artifacts listing requests, e.g. "{{recursive:true,browseArchives:true}}". "recursive:true" dimension allows to list files recursively, "browseArchives:true" treat supported archives as "directories", listing their content
{hidden-data}
<artifact relative name> supports referencing files under archives using "!/" delimiter after the archive name.

Examples:

GET http://teamcity:8111/httpAuth/app/rest/builds/id:100/artifacts/children/my-great-tool-0.1.jar\!/META-INF
GET http://teamcity:8111/httpAuth/app/rest/builds/id:100/artifacts/metadata/my-great-tool-0.1.jar\!/META-INF/MANIFEST.MF
GET http://teamcity:8111/httpAuth/app/rest/builds/id:100/artifacts/metadata/my-great-tool-0.1.jar!/lib/commons-logging-1.1.1.jar!/META-INF/MANIFEST.MF
GET http://teamcity:8111/httpAuth/app/rest/builds/id:100/artifacts/content/my-great-tool-0.1.jar!/lib/commons-logging-1.1.1.jar!/META-INF/MANIFEST.MF

Authentication

If you download the artifacts from within a TeamCity build, consider using teamcity.auth.userId/teamcity.auth.password system properties as credentials for the download artifacts request: this way TeamCity will have a way to record that one build used artifacts of another and will display it on the build's Dependencies tab.

...

Get all changes for a project: GET http://teamcity:8111/app/rest/changes?locator=project:projectId
Get all the changes in a build configuration since a particular change identified by its id: http://teamcity:8111/httpAuth/app/rest/changes?locator=buildType:(id:buildConfigurationId),sinceChange:(id:changeId)
Get pending changes for a build configuration http://teamcity:8111/httpAuth/app/rest/changes?locator=buildType:(id:BUILD_CONF_ID),pending:true

<lastChanges>
The  <lastChanges>  tag contains information about the last commit included into the build and is only good for re-triggering the build: it contains the TeamCity internal id (the id attribute) associated with the commit, which is necessary for TeamCity to trigger a custom build on the same commit (see the example  above   ).

...

Since TeamCity 9.1 there is an experimental ability to retrieve entire build chain (all snapshot-dependency-linked builds) for a particular build:

http://teamcity:8111/httpAuth/app/rest/builds?locator=snapshotDependency:(to:(id:XXXX),includeInitial:true),defaultFilter:false
This gets all the snapshot dependency builds recursively for the build with id XXXX.
