# DevOps Center Custom Platform Events

DevOps Center generates platform events for work items as they move through the development and promotion lifecycle.

In the development phases, DevOps Center generates a platform event every time a work item changes state (New, In Progress, and so on). DevOps Center also generates a platform event for every commit on the work item’s feature branch and when the change request is opened.

In the promotion lifecycle, DevOps Center generates a platform event whenever the work item’s metadata is merged into a pipeline stage. DevOps Center also generates a platform event whenever a work item’s metadata is deployed to a pipeline stage’s org.

You can subscribe to these events using all the methods supported by Salesforce (Apex Triggers, Flows, LWCs, APIs, and so on).
