Immutable. The Cloud Pub/Sub topic that receives events for the
subscription.

Format: `projects/{project}/topics/{topic}`


You must create the topic in the same Google Cloud project where
you create this subscription.

When the topic receives events, the events are encoded as Cloud Pub/Sub
messages. For details, see the [Google Cloud Pub/Sub Protocol Binding for
CloudEvents](https://github.com/googleapis/google-cloudevents/blob/main/docs/spec/pubsub.md).
