Extend the maximum length of a prediction
https://dev.twitch.tv/docs/api/reference#create-prediction - the maximum prediction_window is 1800 seconds (30 minutes). This seems unnecessarily short, there are some predictions I run that could be open for longer.
Imagine a prediction that lasts across the full length of a game, or even an entire stream--these generally run for hours, not just 30 minutes.
Please raise the maximum prediction_window significantly, to at least 2 hours, or longer.
The Twitch API cannot create a Channel Points Prediction with a length longer than what is available in the Creator Dashboard. At this time, Predictions can be set in the dashboard to a number of options from 30 seconds to 30 minutes. Since implementation is not possible, I will close this post, however, I would recommend creating a suggestion in the Predictions category for a longer length. If implemented, that would also result in the API updates for third-party developers.
