Is it possible to trace back to an upstream project via GitLab API?
From the source field I can identify whether the pipeline is part of a multi-project pipeline but I cannot find any id that links upstream and downstream projects.
Pipeline Bridges API only shows downstream projects.
I have multiple projects that may or may not trigger the same downstream project. What I would like to do is go through the pipelines of the downstream project and find the upstream project that triggered it.
