HPE GreenLake for Webhooks
HPE GreenLake for Webhooks provides RESTful APIs to manage webhooks and events programmatically.
Events are actions or changes within HPE GreenLake cloud that trigger a webhook; for example, an audit log was created, or a subscription is due to expire. Webhooks deliver automated messages with event data to the webhook destination URL.
