Hi Vapi Support Team, I'm encountering an issue where my webhook endpoint is not being triggered during Vapi call events (e.g., call.started, call.ended, etc.). Here’s my setup: I'm using vapi.start() with the following server config: server: { url: 'https://19a9b58798bf.ngrok-free.app/webhook/vapi', secret: 'my-shared-secret' } I’ve verified that: The ngrok tunnel is live and forwarding to my local server My webhook is reachable (tested via Postman and curl — all working) I’m running vapi listen --forward-to http://localhost:5000/webhook/vapi No events are received during the call lifecycle Additionally, no breakpoints or logs are hit on my server when a real call starts or ends — but simulated POSTs to the same endpoint work fine. Could you please help me verify: If the webhook URL is properly registered during vapi.start()? If there are any issues on your end preventing event delivery? If I’m missing any required configuration for event triggering?
