# AssociateDefaultView
<a name="API_AssociateDefaultView"></a>

Sets the specified view as the default for the Amazon Web Services Region in which you call this operation. When a user performs a [Search](API_Search.md) that doesn't explicitly specify which view to use, then Amazon Resource Explorer automatically chooses this default view for searches performed in this Amazon Web Services Region.

If an Amazon Web Services Region doesn't have a default view configured, then users must explicitly specify a view with every `Search` operation performed in that Region.

 **Minimum permissions** 

To call this operation, you must have the following permissions:
+  **Action**: `resource-explorer-2:AssociateDefaultView` 

   **Resource**: No specific resource (\*). However, an index must be present in the Amazon Web Services Region in which you call the operation.

 **Related operations** 
+ To remove a view as the default for an Amazon Web Services Region, use [DisassociateDefaultView](API_DisassociateDefaultView.md).
+ To list the available views, use [ListViews](API_ListViews.md).
+ To find which view is the default, use [GetDefaultView](API_GetDefaultView.md).
