After seeing the article here https://blog.twitch.tv/deep-metadata-api-32e506ce6af6 I became interested in the way it talks about other metadata information that can be retrieved about games Overwatch and Hearthstone, specifically the latter.
In the article, it talks about how you can filter for specific rank in Constructed mode or how many wins in the Arena mode. I can see this is functional through the https://www.twitch.tv/directory/game/Hearthstone webpage where using the filters you can select for how many wins someone is at (e.g. 5 Wins for Arena). I am trying to find out how it is possible to retrieve this information through the Twitch API as I cannot find any documentation for it in the documentation.
In the documentation it talks about you can retrieve the Hero that is playing the game in either Overwatch or Hearthstone, but specifically I am looking for the more detailed information as discussed in the article.
