Amazon SNS Example

Some services offer additional conditions that can be used in policies. Amazon SNS provides conditions

for allowing or denying subscriptions to SNS topics based on the protocol (e.g., email, HTTP, HTTPS,

SQS) and endpoint (e.g., email address, URL, SQS ARN) of the request to subscribe to a topic.

* This SNS condition allows you to restrict subscriptions to an Amazon SNS

topic

* based on the requested endpoint (email address, SQS queue ARN, etc.) used

when

* someone tries to subscribe to your SNS topic.

Condition endpointCondition =

SNSConditionFactory.newEndpointCondition("*@mycompany.com");

Policy policy = new Policy().withStatements(

new Statement(Effect.Allow)

.withPrincipals(Principal.AllUsers)

.withActions(SNSActions.Subscribe)

.withConditions(endpointCondition));

AmazonSNS sns = new AmazonSNSClient(myAwsCredentials);

sns.setTopicAttributes(

new SetTopicAttributesRequest(myTopicArn, "Policy", policy.toJson()));
