Hi,
I’ve not seen any news on this either, I’m unsure if it’s being discussed within Twitch, but I’d like to see it implemented. Either way, with the new Affiliate program I feel it’s much easier now - we don’t have to be partnered, and soon Affiliates will have a sub button too, so they’ll have this sort of API eventually. I know not everyone is an affiliate still, but I suppose it’s something for the time being.
