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.

HPE GreenLake has a growing catalog of events that help you get real-time information about your HPE GreenLake infrastructure.
