Event subscription returns "Invalid request" for chat.message.sent

[hasandumanuk-commits]

Hi,

I am trying to subscribe to the chat.message.sent event, but the request always returns 400 Invalid request.

Details:

Endpoint:
POST /public/v1/events/subscriptions

Broadcaster user id:
93350154

Payload:
{"broadcaster_user_id":93350154,"events":[{"name":"chat.message.sent","version":1}]}

Response:
{"data":{},"message":"Invalid request"}

Webhook URL:
https://link-detector.onrender.com/webhook/kick

What I already confirmed:

• My webhook URL is publicly accessible
• My app is deployed and running
• broadcaster_user_id is correct
• OAuth/token flow is working
• /find/broadcaster works correctly
• /subscribe/chat sends the request successfully, but Kick returns Invalid request

Could you please confirm the correct request body and required scopes for subscribing to chat.message.sent?

Thanks.
