# Viewing an action's source code
<a name="workflows-view-source"></a>

You can view an action's source code to make sure it doesn't contain risky code, security vulnerabilities, or other defects.

Use the following instructions to view the source code of a [CodeCatalyst](workflows-actions.md#workflows-actions-types-cc), [CodeCatalyst Labs](workflows-actions.md#workflows-actions-types-cc-labs), or [third-party](workflows-actions.md#workflows-actions-types-3p) action.

**Note**  
To view the source code of a [GitHub Action](workflows-actions.md#workflows-actions-types-github), go to the action's page in the [GitHub Marketplace](https://github.com/marketplace/actions). The page includes a link to the action's repository, where you can find the action's source code.

**Note**  
You cannot view the source code of the following CodeCatalyst actions: [build](build-workflow-actions.md), [test](test-workflow-actions.md), [GitHub Actions](integrations-github-action-add.md).

**Note**  
AWS does not support or guarantee the action code of GitHub Actions or third-party actions.<a name="workflows-to-view-source-cc"></a>

**To view an action's source code**

1. Open the CodeCatalyst console at [https://codecatalyst.aws/](https://codecatalyst.aws/).

1. Choose your project.

1. Find the action whose code you want to view:

   1. In the navigation pane, choose **CI/CD**, and then choose **Workflows**.

   1. Choose the name of any workflow, or create one. For information about creating a workflow, see [Creating a workflow](workflows-create-workflow.md).

   1. Choose **Edit**.

   1. At the top-left, choose **\$1 Actions** to open the action catalog.

   1. In the drop-down list, choose **Amazon CodeCatalyst** to view CodeCatalyst, CodeCatalyst Labs, and third-party actions.

   1. Search for an action, and choose its name. Do not choose the plus sign (**\$1**).

      Details about the action appear.

1. In the action details dialog box, near the bottom, choose **Download**.

   A page appears, showing the Amazon S3 bucket where the action's source code resides. For information about Amazon S3, see [What is Amazon S3?](https://docs.aws.amazon.com/AmazonS3/latest/userguide/Welcome.html) in the *Amazon Simple Storage Service User Guide*.

1. Inspect the code to ensure it meets your expectations for quality and security.
