Remarks

A subscription defines a message source, message target, and a topic (or subject) that's used to route messages from the source to the target. A subscription defines the message flow in one direction, from the source to the target. For two-way communication, you must set up two subscriptions, one for each direction.

In an AWS CloudFormation template, the Subscriptions property of the SubscriptionDefinitionVersion property type contains a list of Subscription property types.
