Stuck on establishing the Notification API WebSocket connection for real-time event ingestion. My gRPC service attempts to upgrade via wss://api.mypurecloud.com/api/v2/analytics/events but receives a 1006 abnormal closure immediately after the initial Sec-WebSocket-Accept response. I am passing a valid OAuth Bearer token in the Authorization header, yet the server drops the connection before I can send the subscription payload.
- Verified token validity via
/api/v2/authorizations/userinfo. - Confirmed endpoint matches the documentation for event streaming.
Any insights on why the handshake fails at this stage? Thanks.
