HSL OpenMaaS sales API

HSL OpenMaaS is an open sales interface for the purchase of Helsinki Region Transport (HSL) mobile tickets. The goal is that all HSL’s mobile ticket products are available through this API. The OpenMaaS interface is constantly developing new technical features, ticket types and payment methods. The OpenMaaS operator can integrate with the HSL OpenMaaS API and create a platform to offer HSL mobile tickets to its own customers. The portal allows you to create an account and log in to manage your organisation’s API keys and payment method information. The API provides functions for searching for ticket types, passenger types and valid areas as well as for purchasing tickets. There are two options for displaying purchased tickets: 1. Integrate HSL’s customer library into the application. 2. Links HSL to a separate utility app available on Google Play and the Apple App Store.
