Hi there! 👋 I see you're having trouble with the VAPI Organization Server. While I can't diagnose exactly why your API calls aren't reaching your server without seeing your specific setup, I can definitely explain what the Organization Server is and provide some troubleshooting steps. ## What is the VAPI Organization Server? The VAPI Organization Server is an organization-wide server URL that you can set in the organization section of your dashboard. According to the [VAPI documentation](https://docs.vapi.ai/server-url/setting-server-urls), if no other server URL is set at more specific levels (like assistant or function level), Vapi will use this organization-level URL by default. ## How it works The server URL gives Vapi a location to: - Send real-time conversation data to your application - Query for data that Vapi needs during conversations - Enable communication between Vapi and your backend services As mentioned in the [VAPI server URL documentation](https://docs.vapi.ai/server-url), Vapi sends various types of events to your server including status updates, transcript updates, function calls, assistant requests, end-of-call reports, and hang notifications. ## Common reasons API calls might not reach your server Since your API calls aren't reaching your server, here are some common causes to check: 1. **URL Configuration**: Verify that the URL format is correct and properly formatted in the VAPI dashboard. 2. **Network Issues**: Ensure ngrok is running correctly and the tunnel is active. Sometimes ngrok tunnels can expire or disconnect. 3. **Webhook Configuration**: Double-check that the webhook URL is correctly configured in VAPI and accessible from the internet. 4. **Server Implementation**: Make sure your Node.js server is correctly set up to receive and process HTTP requests from VAPI. 5. **Firewall/Security Settings**: Check if any firewall or security settings might be blocking incoming requests from VAPI.
