HSL OpenMaaS sales API

From the dataset abstract

HSL OpenMaaS is an open-for-all ticket sales interface for acquiring HSL mobile tickets. The goal is to have all HSL’s mobile ticket products available via this API. The OpenMaaS API is being continuously developed with new technical features, ticket types and payment options.

As an OpenMaaS operator you can integrate into the HSL OpenMaaS API and create a platform through which you can make HSL mobile tickets available to your own customers. In the portal you can sign up and log in to manage your organizations’s API keys and payment details. The API provides endpoints for fetching available ticket types, passenger types, validity regions as well as for purchasing a ticket. To display the bought tickets, you have two options:

1. Integrate HSL’s client library inside your application.
2. Link to HSL’s separate helper application available at Google Play and Apple’s App Store.
