+GitLab CI/CD is a powerful continuous integration tool that works not only per project,
+but also across projects with multi-project pipelines.
Multi-project pipelines are useful for larger products that require cross-project inter-dependencies, such as those
adopting a [microservices architecture](https://about.gitlab.com/blog/2016/08/16/trends-in-version-control-land-microservices/).

## Triggering multi-project pipelines through API

+> - Use of `CI_JOB_TOKEN` for multi-project pipelines was [made available](https://gitlab.com/gitlab-org/gitlab/issues/31573) in all tiers in GitLab 12.4.

When you use the [`CI_JOB_TOKEN` to trigger pipelines](triggers/README.md#ci-job-token), GitLab
recognizes the source of the job token, and thus internally ties these pipelines
together, allowing you to visualize their relationships on pipeline graphs.
