Documented steps
GET https://gitlab.example.com/api/v4/projects/:id/pipelines to list pipelines; filter with ref, status (e.g. running, failed, success), sha, source, scope (running|pending|finished|branches|tags), username, or created_after/updated_after in ISO 8601 format.
Child pipelines are excluded by default — pass source=parent_pipeline to include them; when scope=branches or scope=tags, only the latest pipeline per ref is returned.
GET https://gitlab.example.com/api/v4/projects/:id/pipelines/:pipeline_id to retrieve full detail for one pipeline (status, sha, duration, coverage, etc.), including for a child pipeline.
GET https://gitlab.example.com/api/v4/projects/:id/pipelines/latest?ref=main to get the latest pipeline for the most recent commit on a ref; omit ref to use the project's default branch.
POST https://gitlab.example.com/api/v4/projects/:id/pipelines/:pipeline_id/cancel to cancel all jobs in a pipeline.
Paginate list results with page and per_page query parameters.

Known gotchas
The cancel-pipeline endpoint always returns 200 regardless of whether cancellation actually succeeded (known issue) — poll the pipeline's status afterward to confirm it reached canceled.
pipelines/latest returns 403, not 404, when the specified ref's most recent commit has no pipeline.
Child pipelines are omitted from list-pipelines results unless source=parent_pipeline is explicitly requested.
scope=branches or scope=tags collapses results to only the newest pipeline per ref, which can hide older still-running pipelines on the same branch.
