Promotion Workflows with hooks in Codefresh GitOps have access to a standard set of[default parameters]({{site.baseurl}}/docs/promotions/promotion-hooks/#default-arguments-in-promotion-hooks), such as the release ID, current release version, product, and commit SHA. When you define these parameters in the hook as input parameters, their values are dynamically retrieved from the ongoing promotion.

Promotion hooks in GitOps Cloud are specialized Promotion Workflows that run at key stages of a product release. A product release is created when a Promotion Flow is triggered, either manually or automatically.
