Got 401 but I am sing the proper API key

Please have a look at the screenshot of my postman … and suggest me the cause of getting 401

Don’t use the API Key authentication type, or if you do, set the key to “Authorization” and the value to “apikey lasdjfhakjdhfkjas”. See here for more details: API Basics | TfNSW Open Data Hub and Developer Portal

Thanks Jayen!
