# Setting up dependencies between actions
<a name="workflows-depends-on-set-up"></a>

Use the following instructions to set up dependencies between actions in a workflow.

When configuring dependencies, follow these guidelines:
+ If an action is inside a group, that action can only depend on other actions within the same group.
+ Actions and action groups can depend on other actions and action groups *at the same level* in the YAML hierarchy, but *not* at a different level.

#### [ Visual ]

**To set up dependencies using the visual editor**

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

1. Choose your project.

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

1. Choose the name of your workflow. You can filter by the source repository or branch name where the workflow is defined, or filter by workflow name or status.

1. Choose **Edit**.

1. Choose **Visual**.

1. In the workflow diagram, choose the action that will depend on another action.

1. Choose the **Inputs** tab.

1. In **Depends on - optional**, do the following:

   Specify an action, action group, or gate that must run successfully in order for this action to run.

   For more information about the 'depends on' functionality, see [Sequencing actions](workflows-depends-on.md).

1. (Optional) Choose **Validate** to validate the workflow's YAML code before committing.

1. Choose **Commit**, enter a commit message, and choose **Commit** again.

#### [ YAML ]

**To set up dependencies using the YAML editor**

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

1. Choose your project.

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

1. Choose the name of your workflow. You can filter by the source repository or branch name where the workflow is defined, or filter by workflow name or status.

1. Choose **Edit**.

1. Choose **YAML**.

1. In an action that will depend on another, add code similar to the following:

   ```
   action-name:
     DependsOn:
       - action-1
   ```

For general guidelines, see [Setting up dependencies between actions](#workflows-depends-on-set-up). For more information, see the description of the `DependsOn` property in the [Workflow YAML definition](workflow-reference.md) for your action.
