This interface is used for getting handwritten text operation result. The URL to this interface should be retrieved from “Operation-Location” field returned from Recognize Handwritten Text interface.

This operation needs a operation Id by POST Recognize Handwritten Text api ,so it is stateful?

Answer 1

I'm not entirely sure why whether it's stateful or not is relevant to you, but the answer is clearly yes. Note that the Operation ID is not valid after 48 hours, as noted here.
