Cloud Pub/Sub is an orchestration component that allows messages to be published to a topic on Google Cloud. Other applications can subscribe to these topics to receive such messages.

To use this component, you need to add Google Cloud [credentials](/docs/guides/cloud-credentials) to your {maia} project. You then need to [associate your cloud provider credentials with an environment](/docs/guides/environments#associate-cloud-provider-credentials-with-an-environment) for {designer} to access your Google Cloud account.

To publish messages from {maia}, you must first ensure that topics are available to publish to (and ideally, that relevant applications are subscribed to these topics).

* If you're new to Cloud Pub/Sub, read [Overview of the Pub/Sub service](https://cloud.google.com/pubsub/docs/pubsub-basics).
* Read [Create a topic](https://cloud.google.com/pubsub/docs/create-topic) to get started with topics.

## Properties
