SNS; How to get valid SubscriptionARN after user confirmation
System: Windows, C#, Visual Studio 2015, AWSSDK.SimpleNotificationService
Using AWS-SNS, after creating a topic I add a subscription to the topic as follows;
var response = SnsClient.Subscribe(topicArn, "email", email);
var subscriptionArn = response.SubscriptionArn;
Initially, my subscription ARN is set to "pending confirmation" - presumably until the user confirms their subscription via email. I would have thought that calling subscribe again with the same email subsequent to confirmation would have returned a vilid ARN, but it doesn't seem to work that way.
Not having the subscription ARN prevents me from later unsubscribing an email from a subscription group. I'm sure there is a way to overcome it short of requiring the user to copy / past the email token into my application - but I can't seem to find it.
Thank you in advance.

(PS. I should note that the answer need to be C# specific - just a generic approach to the problem using their SDK or web API is fine.)
The Amazon SNS Subscribe documentation says:
The following element is returned by the service:
SubscriptionArn
The ARN of the subscription, if the service was able to create a subscription immediately (without requiring endpoint owner confirmation).
Therefore, it appears that an Email subscription only receives an ARN when the subscription has been confirmed .
You will need to identify the subscription (once subscribed) by calling ListSubscriptionsByTopic , looking for the Endpoint that matches the desired email address . You could then extract the ARN and use it when calling Unsubscribe .
