Courier Live: Notify Discourse users about your livestream with Twitch EventSub and Courier

On January 6, I was joined by Riley Napier for our first Courier Live of the year, where we explored setting up webhooks using Twitch EventSub and triggering notifications about Twitch livestreams using a Glitch application. We walked through how to set it up, created a notification in Courier, used the Webhook Provider to make a request to the Discourse API to display a banner on the community forum, and personalized the Discourse banner content using Jsonnet. The code for handling Twitch EventSub requests is available in the Courier Twitch EventSub Glitch application, which users can remix and start sending their own Twitch notifications.
