Build reliable journeys. Together with SJ.

Welcome to the SJ Partner API documentation portal.

This is where resellers and partners find everything needed to integrate SJ’s services into their own solutions – clearly explained, easy to use, and built for real-world travel.

Our APIs are designed to help you offer smooth booking experiences, accurate travel information, and dependable journeys across Sweden.

That belief guides how we design our APIs – and how we document them.

Here you’ll find:

Clear and structured API documentation
Practical examples and use cases
Stable, well-defined interfaces

We focus on:

Reliability you can trust
