Issue with TfNSW GTFS-Realtime API: "Policy Falsified" Error (HTTP 500)

Real-time Public Transport

Hi everyone,

I’m working on a web map to display live train positions using the TfNSW GTFS-Realtime Vehicle Positions API (trying /v2 endpoints).

The Problem: I keep getting an HTTP 500 Internal Server Error from the TfNSW API, with the specific message "Policy Falsified".

What I’ve done:

  1. Code Setup: My frontend (JavaScript) is correctly using protobuf.js with the official TfNSW gtfs-realtime_1007_extension.proto file to decode the data. My PHP proxy is also set up correctly to handle requests and pass the API key.
  2. API Key: I’m using a brand new API key generated from the TfNSW Developer Portal.

Crucial Finding (from curl test): To rule out any issues with my code or proxy, I performed a direct curl test to the TfNSW API (https://api.transport.nsw.gov.au/v2/gtfs/vehiclepositions) using my API key.

Even with the curl command (which confirms the Authorization header is perfectly clean and correctly sent), I still receive the HTTP 500 and "Policy Falsified" error.

My Question: Since the error persists even with a clean curl request to the v2 endpoint, it strongly suggests the issue is with my API key itself. Is it possible that newly generated API keys need to be specifically activated or provisioned for access to the live GTFS-Realtime feeds? Or are there other known reasons for this “Policy Falsified” error with active keys?

Any insights or advice would be greatly appreciated!

Thanks.
