Note
This GitHub Action does not yet support CircleCI projects that are integrated with the CircleCI GitHub App. If your CircleCI project URL looks like this: https://app.circleci.com/projects/organizations/circleci%, you are integrating with the CircleCI GitHub App and this GitHub Action is not yet supported. Contact [email protected] with any questions/feedback. If your CircleCI project URL looks like this: https://app.circleci.com/projects/project-dashboard/github/, you are using CircleCI's OAuth App integration and this GitHub Action is supported.
Trigger your CircleCI pipelines from any event on GitHub with GitHub Actions.
-
Create a GitHub Action's workflow for the desired CircleCI pipeline.
Do this by adding a workflow YAML file (we'll use
main.yml) to./.github/workflows.A
releasetrigger is shown in this example. Try any of the GitHub events for triggering workflows: https://docs.github.com/en/actions/learn-github-actions/events-that-trigger-workflowsSelect a custom name and id for the step for additional contextual metadata in your CircleCI pipeline
on:
release:
types: [published]
jobs:
trigger-circleci:
runs-on: ubuntu-latest
steps:
- name: <customize name>
id: <customize id>
uses: CircleCI-Public/[email protected]
env:
CCI_TOKEN: ${{ secrets.CCI_TOKEN }}-
Create an encrypted secret named
CCI_TOKENcontaining the Personal API Token that will be used to trigger the pipelines. This is suggested to be a machine user. -
Add the Pipeline Parameter definitions to your CircleCI config. This data will be entered by the GitHub Action when triggered.
Add the following to the top of your
.circleci/config.ymlfile. Ensure you are specifying version2.1version: 2.1 parameters: GHA_Actor: type: string default: "" GHA_Action: type: string default: "" GHA_Event: type: string default: "" GHA_Meta: type: string default: ""
-
Use the Pipeline Parameter data to run workflows conditionally.
See: Examples
Optional input parameters that allow you to specify additional metadata.

env:
CCI_TOKEN: ${{ secrets.CCI_TOKEN }}| Field | Data Type | Description |
|---|---|---|
id |
string (uuid) | The unique ID of the pipeline. |
state |
string (Enum: "created" "errored" "setup-pending" "setup" "pending") | The current state of the pipeline. |
number |
integer (int64) | The number of the pipeline. |
created_at |
string (date-time) | The date and time the pipeline was created. |
By default, when a repository is connected to CircleCI, if the workflows within that project's configuration does not specify any conditionals or filters that would otherwise prevent execution, the workflow will execute on every push event by default.
This may mean it is possible to accidentally run a job twice, once on the push event from CircleCI, as well as other events triggered by the GitHub Action.
If you are relying on GitHub Actions to provide all of your API triggers, ensure that each of your CircleCI configuration's workflows contains a conditional limiting it's execution to only the GitHub Action trigger.
Example
workflows:
# This workflow is set to be conditionally triggered,
# only via the GitHub Action.
# With no other unfiltered workflows, normal push events will be ignored.
