Common top level keys of webhooks

Each webhook will have some common data as part of the event:

Field	Description	Type
id	ID used to uniquely identify each event from the system (the client can use this to dedupe events)	String
happened_at	ISO 8601 timestamp representing when the event happened	String
webhook	A map of metadata representing the webhook that was triggered	Map

The event payloads are open maps, meaning new fields may be added to maps in the webhook payload without considering it a breaking change.

Common sub-entities of webhooks

The following sections describe the payloads of different events offered with CircleCI webhooks. The schema of these webhook events will often share data with other webhooks. These common maps of data are referred to as "sub-entities". For example, when you receive an event payload for the job-completed webhook, it will contain maps of data for your project, organization, job, workflow and pipeline.

Some common sub-entities that will appear across various webhooks are described in the following sections:

Project

The following data about the project associated with the webhook event is provided:

Field	Always present?	Description
id	yes	Unique ID of the project
slug	yes	String that can be used to refer to a specific project in many of CircleCI’s APIs (for example, `gh/circleci/web-ui`)
name	yes	Name of the project (for example, `web-ui`)

Organization

The following data about the organization associated with the webhook event is provided:

Field	Always present?	Description
id	yes	Unique ID of the organization
name	yes	Name of the organization (e.g. "circleci")

Job

A job typically represents one phase in a CircleCI workload (for example, "build", "test", or "deploy") and contains a series of steps.

The following data about the job associated with the webhook event is provided:

Field	Always present?	Description
id	yes	Unique ID of the job
number	yes	An auto-incrementing number for the job, sometimes used in CircleCI’s APIs to identify jobs within a project
name	yes	Name of the job as defined in .circleci/config.yml
status	yes	Current status of the job
started_at	yes	When the job started running
stopped_at	no	When the job reached a terminal state (if applicable)

Workflow

Workflows orchestrate jobs. The following data about the workflow associated with the webhook event is provided:

Field	Always present?	Description
id	Yes	Unique ID of the workflow
name	Yes	Name of the workflow as defined in .circleci/config.yml
status	No	Current status of the workflow. Not included in job-level webhooks
created\_at	Yes	When the workflow was created
stopped_at	No	When the workflow reached a terminal state (if applicable)
url	Yes	URL to the workflow in CircleCI’s UI

Pipeline

Pipelines are the most high-level unit of work, and contain zero or more workflows. A single git-push always triggers up to one pipeline. Pipelines can also be triggered manually through the API.

The following Data about the pipeline associated with the webhook event is provided:

Field	Always present?	Description
id	Yes	Globally unique ID of the pipeline
number	Yes	Number of the pipeline, which is auto-incrementing / unique per project
created\_at	Yes	When the pipeline was created
trigger	Yes	A map of metadata about what caused this pipeline to be created — see below
trigger_parameters	No	A map of metadata about the pipeline — see below
vcs	No	A map of metadata about the git commit associated with this pipeline — see below

Trigger

The following data about the trigger associated with the webhook event is provided:

Field	Always present?	Description
type	yes	How this pipeline was triggered (for example, "webhook", "api", "schedule")

Trigger parameters

Data associated to the pipeline. Present for pipelines associated with GitLab or GitHub Apps. For parameters available for GitHub OAuth app and Bitbucket integrations, see VCS below. To find out which GitHub integration you have, see the GitHub Apps integration page.

Field	Always present?	Description
circleci	yes	A map containing trigger information — see circleci
git	no	A map present when the pipeline is associated with a VCS provider
gitlab	no	A map present when the pipeline is associated with a GitLab or GitHub App trigger

circleci

Field	Always present?	Description
event_time	yes	ISO 8601 timestamp representing when the pipeline was created
event_type	yes	Provider event type that triggered the pipeline (for example, `push`)
trigger_type	yes	Trigger provider (for example, `gitlab`)
actor_id	no	CircleCI user id that the pipeline was attributed to

VCS

The VCS map and its contents are always present for GitHub OAuth app and Bitbucket projects, but not for GitLab or GitHub App projects. See trigger parameters above for GitLab and GitHub App parameters. To find out which GitHub integration you have, see the GitHub Apps integration page.

Field	Always present?	Description
target_repository_url	no	URL to the repository building the commit
origin_repository_url	no	URL to the repository where the commit was made (this will only be different in the case of a forked pull request)
revision	no	Git commit being built
commit.subject	no	Commit subject (first line of the commit message). Note that long commit subjects may be truncated.
commit.body	no	Commit body (subsequent lines of the commit message). Note that long commit bodies may be truncated.
commit.author.name	no	Name of the author of this commit
commit.author.email	no	Email address of the author of this commit
commit.authored\_at	no	Timestamp of when the commit was authored
commit.committer.name	no	Name of the committer of this commit
commit.committer.email	no	Email address of the committer of this commit
commit.committed_at	no	Timestamp of when the commit was committed
branch	no	Branch being built
tag	no	Tag being built (mutually exclusive with "branch")
