This snazzy update was made possible as a result of our recent OpenAPI v3 adoption, which has enabled us to improve the way we handle long-running tasks. With the addition of "callbacks", async API requests can now be configured to deliver results via a webhook when they are ready.
This is particularly useful in scenarios such as pinging a device for an extended period of time, or running an asynchronous Action Batch to deploy configurations at scale.
