"Streams" Webhook sending incorrect offline payload

API
1

I’ve been using webhooks for several months without a problem, but in the past one month or so, I’ve been receiving erroneous offline payloads almost immediately after receiving a valid stream payload, followed by another valid stream payload.

Here is one example from my logs:

}

    "data": [{
        "game_id": "509658",
        "id": "39934444398",
        "language": "en",
        "started_at": "2020-10-02T17:52:27Z",

    }]
}

About 30 seconds after receiving the first payload (which, compared to the previous one received indicates that the streamer is now live), Twitch sends an offline payload, followed by a payload identical to the first (but with a different Twitch-Notification-Id) another 30 seconds later.

Additionally, fetching https://api.twitch.tv/helix/webhooks/subscriptions yields no duplicated or unexpected subscriptions.

Things I’m currently doing:

  • Recording Twitch-Notification-Id values and discarding duplicate notifications
  • Subscribing to topics with a unique path, e.g. /webhooks/stream_state/207813352
  • Responding to notifications in < 20ms

I’m not sure if I’m doing something wrong or if there is a bug with Twitch, as this happens for multiple streamers and not just HasanAbi.

This is a known issue, tracked here: https://github.com/twitchdev/issues/issues/230

Twitch are looking in to it.

Thanks, glad that I’m not the only one :+1:
