Returns the result of a previously sent request by its X-Request-Id. The X-Action header must be gateway.request.status. Use it when the response to the original request was lost or returned with X-Request-Status = process. The response contains the status of the checked request and the current response of the original method. Results of requests are kept for a limited time; after that the API returns 404.When to useThree identifiers are involved: X-Request-Id of this status request (any new UUID), id in the body (X-Request-Id of the checked request) and response.id (the payment). Repeating the original request with the same X-Request-Id is also safe: the operation is not performed again and the current state is returned.
