Hi @Bobby_Dazzler, doesn’t look like anything is wrong with the Trip Planner API. Please make sure that you read the documentation, that’s the pdf in the dataset, which you can find here [Trip Planner APIs | TfNSW Open Data Hub and Developer Portal](https://opendata.transport.nsw.gov.au/dataset/trip-planner-apis)

If you’re still getting an error please provide an example so we can investigate further.

Thanks,  
Alex

A HTTP 401 error, Unauthorized, is indicative of authentication issues so make sure you’re sending through the correct headers.

Hi @Bobby_Dazzler, if it’s an issue with the API explorer then make sure that you’ve set up your application correctly by following our [user guide](https://opendata.transport.nsw.gov.au/user-guide) and that you’re using the API parameters correctly by following the Trip Planner API documentation.

I just tried it myself and didn’t encounter any errors, see below.

If you encounter further issues please let me know and I’ll investigate further.

Thanks,
