AWS SDK Version 3 for .NET
API Reference

AWS services or capabilities described in AWS Documentation may vary by region/location. Click Getting Started with Amazon AWS to see specific differences applicable to the China (Beijing) Region.

Verifies an endpoint owner's intent to receive messages by validating the token sent to the endpoint by an earlier Subscribe action. If the token is valid, the action creates a new subscription and returns its Amazon Resource Name (ARN). This call requires an AWS signature only when the AuthenticateOnUnsubscribe flag is set to "true".

Note:

This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginConfirmSubscription and EndConfirmSubscription. For Unity the operation does not take CancellationToken as a parameter, and instead takes AmazonServiceCallback<ConfirmSubscriptionRequest, ConfirmSubscriptionResponse> and AsyncOptions as additional parameters.

Namespace: Amazon.SimpleNotificationService
Assembly: AWSSDK.SimpleNotificationService.dll
