I just got a new API today and when I test it at the link below. I get an error saying the API key is not authorized. note that when I tested it I had my correct API key in the URL

https://bustime.mta.info/api/siri/stop-monitoring.json?key={insert-api-code}&MonitoringRef={401912}&LineRef={M104}

this is the message I get.... {"Siri":{"ServiceDelivery":{"ResponseTimestamp":"2025-09-25T18:50:53.862-04:00","VehicleMonitoringDelivery":[{"ResponseTimestamp":"2025-09-25T18:50:53.862-04:00","ErrorCondition":{"OtherError":{"ErrorText":"API key is not authorized."},"Description":"API key is not authorized."}}]}}}
