Sorry if this has been raised before but am having trouble requesting multiple histories via HTTP API. I am running nHaystack on Niagara 4.10. Is the batch hisRead functionality still supported?
When following the Example Request from Standard Operations (as per below), it throws an error. Note single point reads work.
This functionality is not yet implemented in nhaystack.
Cheers, Richard

Any update on the batch history read operations? Is it available on Nhaystack 3.3.0.0? Do you know what the minimum Niagara version is that supports 3.3.00? We are running Niagara 4.13.
