Create and resolve a channel Predictions event using the Twitch Helix API

Steps
Obtain a user access token with the channel:manage:predictions scope for the broadcaster (channel:read:predictions is sufficient for read-only access)
Call POST /helix/predictions with the broadcaster ID, prediction title, an array of 2-10 outcome titles, and a prediction window to create the event
Poll or read GET /helix/predictions to display the live prediction and outcome point totals to viewers
When the outcome is known, call PATCH /helix/predictions with status=LOCKED to stop new votes, then again with status=RESOLVED and the winning_outcome_id to pay out points
Handle status=CANCELED as a fallback path if the prediction needs to be voided and refunded instead of resolved
Known gotchas
Only one active prediction can run per channel at a time — attempting to create a second while one is ACTIVE or LOCKED will fail
A prediction must be resolved within 24 hours or Twitch automatically refunds all channel points, so a backend outage during that window silently voids the event
The Predictions API is restricted to Partner and Affiliate broadcasters; calls for non-monetized channels will be rejected
