# Sequencing gates and actions
<a name="workflows-gates-depends-on"></a>

In Amazon CodeCatalyst, you can set up a gate to run before or after a workflow action, action group, or gate. For example, you might set up an `Approval` gate to run before a `Deploy` action. In this case, the `Deploy` action is said to *depend on* the `Approval` gate.

To set up dependencies between gates and actions, configure the gate or action's **Depends on** property. For instructions, see [Setting up dependencies between actions](workflows-depends-on-set-up.md). The referenced instructions refer to workflow *actions* but apply equally to gates. 

For an example of how to set up the **Depends on** property with a gate, see [Example: An 'Approval' gate](workflows-approval-example.md).

For more information about gates, see [Gating a workflow run](workflows-gates.md).

For more information about workflow actions, see [Configuring workflow actions](workflows-actions.md).
