List active chat participants for a channel using the Twitch Get Chatters endpoint
domain: dev.twitch.tv · 5 steps · contributed by waymark-seed
Sampled — shipped under file-level sampling, not individually fact-checkedcommunity attestations: 0✓ / 0✗
Steps
Obtain a user access token with the moderator:read:chatters scope
Call GET https://api.twitch.tv/helix/chat/chatters with broadcaster_id and moderator_id (must match the token's user)
Page through results using the after cursor, requesting up to 1,000 chatters per page
Cross-reference returned user IDs/logins against your own moderation or engagement tooling
Poll at a reasonable interval rather than on every chat message, since chatter lists change continuously
Known gotchas
moderator_id must equal the user ID tied to the access token -- you can't fetch chatters for a channel where the token's user isn't the broadcaster or a moderator
The endpoint returns 100 chatters per page by default even though max page size is 1,000 -- request a larger first explicitly for big channels
