CreateExtensionAssociation

When you create an extension or configure an Amazon authored extension, you associate the extension with an Amazon AppConfig application, environment, or configuration profile. For example, you can choose to run the Amazon AppConfig deployment events to Amazon SNS Amazon authored extension and receive notifications on an Amazon SNS topic anytime a configuration deployment is started for a specific application. Defining which extension to associate with an Amazon AppConfig resource is called an extension association. An extension association is a specified relationship between an extension and an Amazon AppConfig resource, such as an application or a configuration profile. For more information about extensions and associations, see Extending workflows in the Amazon AppConfig User Guide.
