Documented steps

  1. To cancel an entire running workflow: POST https://circleci.com/api/v2/workflow/{id}/cancel with header Circle-Token: $CIRCLE_TOKEN. Returns 202 on success.
  2. To cancel a single job by its job-id (uuid): POST https://circleci.com/api/v2/jobs/{job-id}/cancel with header Circle-Token: $CIRCLE_TOKEN.
  3. Alternative job-cancel path using project-slug + numeric job_number instead of a job uuid: POST https://circleci.com/api/v2/project/{project-slug}/job/{job-number}/cancel with header Circle-Token.
  4. Cancellation puts the workflow/job into the terminal 'canceled' state, which then makes it eligible for a subsequent rerun via the /workflow/{id}/rerun endpoint.
