Routing API

Routing API provides a way to plan itineraries and query public transportation related information about stops and timetables using GraphQL.

Getting started

If you are not familiar with GraphQL, start by reading the GraphQL page.

It is also recommended to try building queries and exploring the schema in GraphiQL.

Real-time arrival prediction page has information about the real-time data available in the API.

Glossary page has explanations for terms commonly used in the API.

After this, you are ready to run queries for routes, stops, city bikes and bicycling routes, disruption info and do itinerary planning.

Endpoints

  1. The routing API for Timisoara region is available at:
    https://api.opentransport.ro/routing/v1/routers/timisoara/index/graphql
  2. The routing API for Romania as a whole is available at:
    https://api.opentransport.ro/routing/v1/routers/romania/index/graphql

API requirements

When sending queries, there are some things you should be aware of:

  1. The HTTP method must be POST
  2. You will get a HTTP 405 error when using other methods.
  3. Content-Type must be either "application/graphql" or "application/json"
  4. You will get a HTTP 415 Error if this header is not present.
