createExtension

Creates an AppConfig extension. An extension augments your ability to inject logic or behavior at different points during the AppConfig workflow of creating or deploying a configuration.

You can create your own extensions or use the Amazon Web Services authored extensions provided by AppConfig. For an AppConfig extension that uses Lambda, you must create a Lambda function to perform any computation and processing defined in the extension. If you plan to create custom versions of the Amazon Web Services authored notification extensions, you only need to specify an Amazon Resource Name (ARN) in the Uri field for the new extension version.

• For a custom EventBridge notification extension, enter the ARN of the EventBridge default events in the Uri field.

• For a custom Amazon SNS notification extension, enter the ARN of an Amazon SNS topic in the Uri field.

• For a custom Amazon SQS notification extension, enter the ARN of an Amazon SQS message queue in the Uri field.

For more information about extensions, see Extending workflows in the AppConfig User Guide.
