App developers in Ireland with an interest in building apps which use realtime public transport information will be familiar with the National Transport Authority’s RTPI REST API.
The RTPI REST API provided various endpoints where a GET request could retrieve realtime bus stop information, route information and more. A dream for app developers!
This API has now been deprecated and replaced by the GTFS Real-Time API.
The newer API will require a little more work to get realtime transport information in your app, however rest assured this article will help you to get going. TL;DR at the bottom 😀
