One of the ways to advance GitLab as a product is to offer several ways to integrate with other products. This also aligns with the Unix and open source philosophy of creating small, interoperable utilities. On a technical level, there are three ways to accomplish this:

• Using webhooks (event mechanisms, asynchronous, and so on. For more information, go to https://gitlab.com/gitlab-org/gitlab-ce/blob/master/doc/web_hooks/web_hooks.md).
• Using the GitLab API (proactively get information from GitLab).
• Using project integration (running from a repository in GitLab). In the settings, four options are available: Elasticsearch, PlantUML, Snowplow, and the ability to view third-party offers.
