Translink Public Transport API

About the API

This API allows developer access to the same underlying Transport planning data from Translink’s journey planner in JSON format. This is also the same published data used by the Translink website, station screens, and Translink NI app, so information accessed should be as live and current as Translink’s core system. You can query the Journey planner API to return many different types of information including the following:

  • Journey plans
  • Departure boards
  • Bus stops
  • Incident information

More information about the API can be found in the guidance document for developers which will be provided on sign up for a registration key.
