Request analytics for a Book to be computed behind the scenes. You'll be notified when they're ready.
You can retrieve the results when they're ready by registering a webhook that listens for the
ANALYTICS_COMPLETED event. You can also poll the Async Analytics Result endpoint regularly if you don't mind exchanging precision for simplicity.
Multiple endpoints, one object
The asynchronous results endpoint and the synchronous version return analytics objects in the same format. The XLSX endpoint logically returns most of the same information, but does not use the same schema since JSON schemas don't apply to Excel files. You can find a detailed reference of the returned analytics object here.
