Subscription Methods

Integrators must choose a subscription method through which they will receive notifications, with options including:

If the integrator requires durable messaging (also known as guaranteed delivery), then it is recommended to subscribe using Amazon Simple Queue Service (SQS). Integrators that require integration not only for application-to-application integration, but also for application-to-person, such as Short Message Service (SMS), email, and push notifications, where filtering and batching are necessary, can subscribe using Amazon Simple Notification Service (SNS). HTTP and HTTPS subscriptions can be setup to retry delivery, but for only a maximum of one hour after the initial notification was created. After one hour, the message will no longer be available.
