In the Twitch Dashboard in Stream summary (or something similar my Twitch is in french) you can export your stream summary in a CSV file. I would like to know if there is any way to access to this data with the API.
My goal would be to have the viewers counter of past broadcasts, do you have any idea how to do that?
I would also want to know with the regular download from the Dasboard, how long can I get this data? From how old brodcasts?
