#exec ⇒ Object

Does cURL data interpretation

Exceptions: SDKErrorResponseException if the remote response is an error. A server response is interpreted as an error if obtained status code differs from expected status code. Expected status codes are ‘200 OK` for GET/POST/PUT, `204 No Content` for DELETE. SDKBadJSONResponseException if the remote response contains erronated or invalid JSON contents

Returns: Hash – In case of successful request, a JSON decoded object is returned. Boolean – If a DELETE request is issued, returns true if call is successful (exception otherwise).
