Today we released webhooks for game analytics and users. Webhooks enable you to get access to updated information as soon as possible, without needing to rely on polling. Check out the documentation.
Please note that the webhooks have the same security as the endpoints. This means that you can get information about game analytics only if you’re authorized, and you can get different information about user changes if you are authorized for the users webhook.
And as a reminder, you can find all documentation updates under the release notes section of the Twitch Developer site.
