Subject: Bug Report: channel.follow v2 EventSub WebSocket Not Sending Notifications

Dear Twitch Developer Support,

I am reporting a bug in the EventSub API where channel.follow v2 subscriptions over WebSocket are not delivering notifications, despite being correctly configured and enabled.

SUMMARY

When subscribing to channel.follow events via WebSocket transport, the subscription is created successfully and shows status "enabled" in the API. However, no notifications are received when users follow the channel. In contrast, other EventSub subscriptions (such as channel.chat.message) on the same WebSocket connection work correctly.

TEST ENVIRONMENT

Bot Account:
- Username: mupongpongbot
- User ID: 1535275845
- Role: Moderator of target channel

Broadcaster Account:
- Username: musicfortheworld__
- Broadcaster ID: 1536964012

Test Account Used for Follow:
- Username: musicrelaxationandhealing (brand new account, never followed before)
- User ID: 1539409101

OAUTH SCOPES

The bot's OAuth token includes these relevant scopes:
- moderator:read:followers ✓
- moderator:read:moderators ✓
- moderator:read:chatters ✓
- user:read:chat ✓
- user:write:chat ✓
- user:bot ✓

STEPS TAKEN

1. Created EventSub WebSocket session

   • Session ID: AgoQDh0I7VS6Saar41kPxTTWhRIGY2VsbC1h
   • Status: Connected ✓

2. Subscribed to channel.follow v2 with correct conditions:
   json
{
"type": "channel.follow",
"version": "2",
"condition": {
"broadcaster_user_id": "1536964012",
"moderator_user_id": "1535275845"
},
"transport": {
"method": "websocket",
"session_id": "AgoQDh0I7VS6Saar41kPxTTWhRIGY2VsbC1h"
}
}


3. API Response confirms subscription is enabled:
   
Type: channel.follow
Version: 2
Status: enabled
Transport: websocket
Session ID: AgoQDh0I7VS6Saar41kPxTTWhRIGY2VsbC1h
Condition: broadcaster_user_id=1536964012, moderator_user_id=1535275845


4. Verified channel.chat.message works on same WebSocket:
   json
{
"metadata": {
"message_type": "notification",
"subscription_type": "channel.chat.message",
"subscription_version": "1"
},
"payload": {
"event": {
"broadcaster_user_id": "1536964012",
"chatter_user_id": "1539409101",
"message": {"text": "232323"}
}
}
}


5. Had test account (musicrelaxationandhealing) follow the channel

6. Confirmed follow was recorded in API:
   
GET /helix/channels/followers?broadcaster_id=1536964012
Response shows: musicrelaxationandhealing is now a follower with followed_at timestamp


7. Expected: WebSocket notification for channel.follow event
   Actual: No notification received

VARIATIONS TESTED

✓ Tested with brand new account (never followed before)
✓ Tested after waiting 10+ seconds for subscription to propagate
✓ Tested removal of moderatoruserid → API rejected with "moderatoruserid failed on 'required' tag"
✓ Tested on same WebSocket session that successfully receives chat messages
✓ Verified follow exists in /helix/channels/followers endpoint
✓ Confirmed bot is moderator of channel
✓ Confirmed bot is follower of channel (in followers list)

ISSUE DETAILS

The problem appears to be one of the following:

1. WebSocket Limitation: channel.follow v2 EventSub notifications may not be supported over WebSocket transport, despite the API allowing subscriptions to be created.

2. Parsing Bug: Twitch may be sending follow notifications that TwitchLib is not parsing correctly.

3. Permission Issue: There may be an undocumented permission requirement or condition preventing notifications from being sent.

REQUEST

Could you please:

1. Confirm whether channel.follow v2 notifications are officially supported over WebSocket transport
2. Investigate why the subscription shows "enabled" but never delivers notifications
3. Clarify if there are any known limitations or bugs with channel.follow v2 WebSocket subscriptions
4. Suggest whether REST webhooks are required for channel.follow events instead of WebSocket

Thank you for your assistance in investigating this issue.

Best regards
