# List of predefined variables
<a name="workflow-ref-action-variables"></a>

Consult the following sections to view the predefined variables produced automatically by CodeCatalyst actions as part of a workflow run.

For more information about predefined variables, see [Using predefined variables](workflows-using-predefined-variables.md).

**Note**  
This list only includes predefined variables emitted by the CodeCatalyst source and [CodeCatalyst actions](workflows-actions.md#workflows-actions-types). If you're using other types of actions, such as GitHub Actions or CodeCatalyst Labs actions, see instead [Determining which predefined variables your workflow emits](workflows-working-with-variables-determine-output-vars.md).

**List**

**Note**  
Not all CodeCatalyst actions produce predefined variables. If the action is not in the list, then it does not produce variables.
