Perform multiple price updates asynchronously in a batch. The response will contain a single GUID to identify the batch. All price updates
are applied to the inventory of the seller indicated by the bearer token used to make this request. When the batch has been processed, a message
will be sent to your application's web hook containing the GUID from this response.
