Builds API

Build number vs build ID

All builds have both an ID which is unique within the whole of Buildkite (build ID), and a sequential number which is unique to the pipeline (build number).

For example build number 27 of the Test pipeline might have a build ID of f62a1b4d-10f9-4790-bc1c-e2c3a0c80983.

API requests that affect a single build accept the more human readable build number (and the organization and pipeline it belongs to), not the build ID:

List all builds

Returns a paginated list of all builds across all the user's organizations and pipelines. If using token-based authentication the list of builds will be for the authorized organizations only. Builds are listed in the order they were created (newest first).

curl -H "Authorization: Bearer $TOKEN" \
  -X GET "https://api.buildkite.com/v2/builds"

Optional query string parameters:

branch Filters the results by the given branch or branches.

Example: ?branch=main returns all builds on the main branch

Example: ?branch[]=main&branch[]=testing returns all builds on main and testing branches
commit Filters the results by the commit (only works for full SHA, not for shortened ones).

Example: ?commit=long-hash

You can query for multiple commits using Rails array syntax:

Example: ?commit[]=sha2&commit[]=sha1
created_from Filters the results by builds created on or after the given time (in ISO 8601 format)

Example: ?created_from=2024-04-15T15:02:34Z
created_to Filters the results by builds created before the given time (in ISO 8601 format)

Example: ?created_to=2024-05-20T15:02:34Z
creator Filters the results by the user who created the build

Example: ?creator=5acb99cf-d349-4189-b361-d1b9f36d70d7
finished_from Filters the results by builds finished on or after the given time (in ISO 8601 format)

Example: ?finished_from=2024-04-18T15:02:34Z
include_retried_jobs Include all retried job executions in each build's jobs list. Without this parameter, you'll see only the most recently run job for each step.

Example: ?include_retried_jobs=true
meta_data Filters the results by the given meta-data.

Example: ?meta_data[some-key]=some-value
state Filters the results by the given build state. The finished state is a shortcut to automatically search for builds with passed, failed, blocked, canceled states.

Valid states: running, scheduled, passed, failing, failed, blocked, canceled, canceling, skipped, not_run, finished

Example: ?state=passed returns all passed builds

Example: ?state[]=scheduled&state[]=running returns all scheduled and running builds

Required scope: read_builds

Success response: 200 OK

List builds for an organization

Returns a paginated list of an organization's builds across all of an organization's pipelines. Builds are listed in the order they were created (newest first).

Success response: 200 OK

Timestamp attributes

There are several different timestamps relating to timing for builds and jobs. There are four main time values which are available on both build and job API calls.

The timestamps are available using both the GraphQL and REST APIs. They differ slightly between the build and job objects.

Each build is provided with the following timestamps:

scheduled_at The time the build was created. All builds from a pipeline upload have a scheduled_at copied from the job that did the uploading
created_at The time the build was created. For uploaded pipelines it is when the pipeline upload was run.
started_at The time the build's first job was started by an agent
finished_at The time the build is marked as finished (passed, failed, paused, cancelled)

Each job is provided with the same timestamps, but their values differ from those on each build:

scheduled_at The time when the scheduler process processes the job. If a job was created after the build, the job's scheduled_at value will inherit the build's created_at value, because of this it can be earlier than the job's created_at timestamp.
created_at The time when the job was added to the build
runnable_at The time when a job was ready to be accepted by an agent
started_at The time the job was started by an agent
finished_at The time the job is marked as finished (passed, failed, paused, cancelled)
