+:description: Newsletter subscription example in Serverless Workflow
+:keywords: kogito, workflow, serverless
+:flow_newsletter_subscription_url:
{kogito_sw_examples_url}/serverless-workflow-newsletter-subscription
+
+This example demonstrates a few features powered by the {product_name}
following the Serverless Workflow specification including:
+
+* REST Services calls via OpenAPI definitions
+* Pause and resume of a given workflow instance
+* Consuming and producing CloudEvents
+
+In a Knative environment, the services involved in this use case can be scaled
to zero and resume from the exact stage it was, saving cluster resources in the
process.
+
+The figure below illustrates the overall architecture of this use case.

+
+. Once a new subscription request comes, the flow will evaluate if it's not
already subscribed.
+. If not, it will attempt to subscribe the new user and wait for the
confirmation.
+. Once a new event containing the confirmation arrives, the flow will resume
and subscribe the new user.
+. Subscriptions that are not confirmed during a configured period of time, are
considered timed-out and are automatically removed from the system.
+. By the end, a new event containing the details of the subscription is
broadcasted in the environment, so other actors can react upon it.
