# Action structure reference
<a name="action-reference"></a>

This section is a reference for action configuration only. For a conceptual overview of the pipeline structure, see [CodePipeline pipeline structure reference](reference-pipeline-structure.md).

Each action provider in CodePipeline uses a set of required and optional configuration fields in the pipeline structure. This section provides the following reference information by action provider:
+ Valid values for the `ActionType` fields included in the pipeline structure action block, such as `Owner` and `Provider`.
+ Descriptions and other reference information for the `Configuration` parameters (required and optional) included in the pipeline structure action section.
+ Valid example JSON and YAML action fields.

This section is updated periodically with more action providers. Reference information is currently available for the following action providers:
