Microsoft has now released the Groove Music API documentation on their Docs website. Groove Music API makes it easy for developers to connect their app or website to the world of Groove. The Groove Music API provides access to RESTful web services that offer many features and generate useful data. It also supports the Microsoft Affiliate Program that includes both streaming premium subscriptions and on-demand purchases.
Recently, we saw Forza team making use of these APIs. For the first time ever, you can rock music you choose as you drive the Horizon with a Groove Music Pass on Xbox One or PC.
To know how you can integrate Groove Music APIs into your app, check out the full documentation here.
