CircleCI V1 API Overview

The CircleCI API is a full-featured RESTful API that allows you to access all information and trigger all actions in CircleCI. RESTful APIs enable you to call individual API endpoints to perform the following actions:

Authentication

The CircleCI API utilizes token-based authentication to manage access to the API server and validate that a user has permission to make API requests. Before you can make an API request, you must first add an API token and then verify that you are authenticated by the API server to make requests. The process to add an API token and have the API server authenticate you is described in the sections below.

Note You may use the API token as the username for HTTP Basic Authentication, by passing the -u flag to the curl command.

Add an API Token

$ curl -H "Circle-Token: <circle-token>" https://circleci.com/api/v1.1/me

{
  "user_key_fingerprint" : null,
  "days_left_in_trial" : -238,
  "trial_end" : "2011-12-28T22:02:15Z",
  "basic_email_prefs" : "smart",
  "admin" : true,
  "login" : "pbiggar"
 }

To add an API token, perform the steps listed below.

  1. Add an API token from your account dashboard.
  2. To test it, View it in your browser or call the API using
  3. You should see a response similar to the example shown in the right pane.

Get Authenticated

curl -H "Circle-Token: <circle-token>" "https://circleci.com/api/..."

curl -u <circle-token>: "https://circleci.com/api/..."

curl "https://circleci.com/api/v1.1/me?circle-token=<circle-token>"

You can add the API token using your account dashboard. Both personal and project API tokens are supported for API v1, however, we recommend using personal API tokens at this time as project API tokens are not supported for API v2.

To be authenticated by the API server, use this as the value of the Circle-Token header:

Or you can use the API token as the username for HTTP Basic Authentication, by passing the -u flag to the curl command:

DEPRECATED (this option will be removed in the future): The API token can be added to the circle-token query param:

Summary of API Endpoints

All CircleCI API endpoints begin with https://circleci.com/api/v1.1/

GET Requests

API Description
/me Provides information about the signed in user.
/projects Lists all projects you are following on CircleCI, with job information organized by branch.
/project/:vcs-type/:username/:project Returns a summary for each of the last 30 job runs for a single project.
/recent-builds Returns a summary for each of the last 30 recent job runs, ordered by build_num.
/project/:vcs-type/:username/:project/:build_num Returns full details for a single job run. The response includes all of the fields from the job summary. This is also the payload for the notification webhooks, in which case this object is the value to a key named ‘payload’.
/project/:vcs-type/:username/:project/:build_num/artifacts Lists the artifacts produced by a given job run.
/project/:vcs-type/:username/:project/checkout-key/:fingerprint Retrieves a checkout key.

POST Requests

API Description
/project/:vcs-type/:username/:project/follow Follow a new project on CircleCI.
/project/:vcs-type/:org_name/:project/:build_num/retry Retries the job, returns a summary of the new job run.
/project/:vcs-type/:username/:project/:build_num/cancel Cancels the job, returns a summary of the job run.
/project/:vcs-type/:username/:project/:build_num/ssh-users Adds a user to the job's SSH permissions.
/project/:vcs-type/:username/:project/tree/:branch Triggers a new job, returns a summary of the job run. Optional build parameters can be set.
/project/:vcs-type/:username/:project/ssh-key Creates an SSH key used to access external systems that require SSH key-based authentication.
/project/:vcs-type/:username/:project/checkout-key Creates a new checkout key.

DELETE Requests

API Description
/project/:vcs-type/:username/:project/checkout-key/:fingerprint Deletes a checkout key.
/project/:vcs-type/:username/:project/ssh-key Delete the SSH key from a project.

Getting Started

API Syntax

When making an API request, make sure you follow standard REST API syntax and formatting. Adhering to proper REST API syntax ensures that the API server can properly process your request and return a JSON response. To make a request to the CircleCI API, use the format shown in the pane to the right:

"https://circleci.com/api/v1.1"

Where:

Version Control Systems

curl https://circleci.com/api/v1.1/project/:vcs-type/:username/:project/tree/:branch

New with v1.1 of the API, for endpoints under /project` you will now need to tell CircleCI what version control system type your project uses. You may currently select either ‘github’ or ‘bitbucket’. The command for recent builds for a project would be formatted like the example shown in the right pane.

Rate Limiting

The CircleCI API is protected by a number of rate limiting measures to ensure the stability of the system. We reserve the right to throttle the requests made by an individual user, or the requests made to individual resources in order to ensure a fair level of service to all of our users.

As the author of an API integration with CircleCI, your integration should expect to be throttled, and should be able to gracefully handle failure. There are different protections and limits in place for different parts of the API. In particular, we protect our API against sudden large bursts of traffic, and we protect against sustained high volumes of requests, for example, frequent polling.

For HTTP APIs, when a request is throttled, you will receive HTTP status code 429. If your integration requires that a throttled request is completed, then you should retry these requests after a delay, using an exponential backoff. In most cases, the HTTP 429 response code will be accompanied by the Retry-After HTTP header. When this header is present, your integration should wait for the period of time specified by the header value before retrying a request.

List Ordering

There are two API endpoints where the list order is significant:

In both cases, jobs are returned in the order that they were created. For all other endpoints, the order has no special significance.

Accept Header

curl https://circleci.com/api/v1.1/me -H "Accept: application/json" -H "Circle-Token: <circle-token>"

If no accept header is specified (or it is empty), CircleCI will return the data in a Clojure EDN format. To receive the data as nicely formatted JSON, include any value for the Accept header (e.g text/plain). If you prefer to receive compact JSON with no whitespace or comments, use application/json as the Accept header.

Cache-Control Header

Some CircleCI APIs may emit a Cache-Control header to indicate that the response may be cached for a period of time. This feature can be used to avoid unnecessary re-fetching of data that will not change. If you plan to make a large volume of API requests you are strongly encouraged to make use of this header in order to improve your performance and lower your risk of being rate limited.

F/OSS

If you have a Free / Open Source Software (F/OSS) project, and have the setting turned on in Advanced Settings in your project dashboard, some read-only /project endpoints will return the requested data without the need for a token. People will also be able to view the job results dashboard for the project as well.

User

curl https://circleci.com/api/v1.1/me -H "Circle-Token: <circle-token>"

{
  "basic_email_prefs" : "smart", // can be "smart", "none" or "all"
  "login" : "pbiggar" // your github username
}

GET Request: Provides information about the user that is currently signed in.

Projects

If you would like to retrieve detailed information about projects, CircleCI provides several different endpoints that you may call to return this information, including the ability to return detailed information for all projects. To ensure you do not encounter any performance-related lags or issues when making an API request, you may wish to limit your search for a single project instead of an array of projects.

The sections below describe the endpoints you may call to return Project information.

Request Type: GET

Returns a job summary for each of the last 30 recent job runs, ordered by build_num.

Parameter Description
limit The number of job runs to return. Maximum 100, defaults to 30.
offset The API returns job runs starting from this offset, defaults to 0.
shallow An optional boolean parameter that may be sent to improve performance if set to 'true'.

Note: When making an API request for Project information, you may experience performance lag and a decrease in overall performance while the request is being processed by the server. To improve performance, CircleCI recommends you pass the shallow parameter in your request.

GET Request: Returns a job summary for each of the last 30 job runs for a single project, ordered by build_num.

Parameter Description
limit The number of jobs to return. Maximum 100, defaults to 30.
offset The API returns jobs starting from this offset, defaults to 0.
filter Restricts which jobs are returned. Set to "completed", "successful", "failed", "running", or defaults to no filter.
shallow An optional boolean value that may be sent to improve overall performance if set to 'true.'

Note: You can narrow the jobs to a single branch by appending /tree/:branch to the url. Note that the branch name should be url-encoded.

Improving Performance In Recent Job Requests Using the Shallow Parameter

When making API requests for information about recent job runs, you may experience performance lag and a decrease in overall performance while the request is being processed by the server. To improve performance, CircleCI recommends you pass the shallow parameter in your request.

curl https://circleci.com/api/v1.1/recent-builds?limit=1&shallow=true

[ {
  "vcs_url" : "https://github.com/circleci/mongofinil",

  "committer_name" : "Allen Rohner",
  "committer_email" : "arohner@gmail.com",
  "subject" : "Don't explode when the system clock shifts backwards",

  "build_time_millis" : 23505,
  "username" : "circleci",
  "reponame" : "mongofinil",
  "lifecycle" : "finished", // :queued, :not_run, :not_running, :running or :finished
  "outcome" : "failed", // :canceled, :infrastructure_fail, :timedout, :failed, :no_tests or :success
  "status" : "failed", // :retried, :canceled, :infrastructure_fail, :timedout, :not_run, :running, :failed, :queued, :not_running, :no_tests, :fixed, :success
  "retry_of" : null, // build_num of the job that this is a retry of
  "previous" : { // previous job
    "status" : "failed",
    "build_num" : 21
  }, ... ]

Sample Request Using the Shallow Parameter

The example to the right shows a user request for recent job information. Notice that when the user passes the shallow parameter, a limited set of information is returned, thereby improving response time and minimizing performance lag.
