Trafikverket Open API

What is Trafikverkets open API?

Trafikverkets open API is an API to fetch information regarding road and rail traffic.

How do I use Trafikverkets open API?

A valid API key is required. This key can be obtained from the Trafiklab developer portal.

This API has multiple versions, all using the same API key. You should use the latest available endpoint, but can keep using earlier ones if you have an existing application.

    1https://api.trafikinfo.trafikverket.se/v2/data.json
    1https://api.trafikinfo.trafikverket.se/v2/data.xml

    You can use Trafikverkets open API by sending a POST-request, which describes which data you’d like to request, along with optional filters. The data is returned in JSON or XML format, depending on the suffix provided in the request.

    A request can look like this:

    1<REQUEST>
2  <LOGIN authenticationkey="YourTrafiklabKey" />
3  <QUERY objecttype="SomeObjectType" schemaversion="SomeObjectVersion" limit="10">
4  <FILTER>
5    <EQ name="SomeDataField" value="2" />
6  </FILTER>
7  </QUERY>
8</REQUEST>
    If there is no value for a requested field, the field will not be included in the response

    The following data types are available:

    Data typeDescription
    TrainMessageMessages related to works on railroads, technical problems, and similar.
    TrainStationStop places, not only for passengers but also for cargo and borders
    TrainAnnouncementTimetable information, in other words, information regarding trains at stops or stations. Does not include cargo trains

    Coordinates
