Trafikverket API

Trafikverket data is useful for transport apps and public dashboards. Apiverket makes common traffic signals easier to test.

Fetch traffic messages, road conditions and infrastructure-related data with consistent authentication and responses.

What can you fetch?

Traffic messages
Road conditions
Infrastructure endpoints
Traffic flow and travel time signals

What can you build?

Traffic dashboards
Commuter tools
Municipal operations
Logistics and travel planning prototypes

Common problems with the original source

Source APIs can require specific query shapes.
Real-time transport data needs careful caching.
Different transport domains are spread across separate structures.

How Apiverket makes it easier

Start with runnable examples.
Use normalized error handling and JSON responses.
Combine traffic with weather, municipal and event data.

Example request

/v1/transport/traffic?limit=20/v1/traffic/messages?limit=5/v1/road-conditions

curl

curl "https://apiverket.se/v1/traffic/messages?limit=5" \
  -H "Authorization: Bearer sk_test_demo"

Freshness: Traffic and road data use short cache windows where the upstream source is time-sensitive.

Source: Apiverket is independent from Trafikverket. Always show freshness clearly in traffic-facing products. Trafikverket.
