return related pipeline id when trigger build through the API.
Description
Response when trigger build through the api likes below: { "id": 41, "variables": { "foo": "bar"} } what does the response 'id' stand for, it seems not the runner id, not the build id, not the pipeline id. It will be convenient if 'pipeline id' be returned from the response to do further usage .
Proposal
{ "id": 41, "variables": { "foo": "bar"} , "pipline_id": 30, "build_id": [51, 52]}
