My End of Call Report Webhook is returning a 413 error and is not reaching my server. Below are some details to help you investigate: Error {"message":"Request failed with status code 413"} Org ID 61d09b13-129f-4353-9eb3-0e7ee89eb6b8 Call ID 019a0c24-30e0-7aa5-b33b-168abff7b635 Assistant ID 41dcc534-e90c-43f8-b25c-f1cc7f9ba83c Phone Number ID c9530863-c4b9-4296-b7f6-e5885e455373

Your 413 error means the webhook payload is too large for your server to accept. If you're using Express.js, increase the request size limit by adding this to your server setup:

js
app.use(express.json({ limit: '50mb' }));
app.use(express.urlencoded({ limit: '50mb', extended: true }));

Restart your server after making this change. This should allow your End of Call Report webhook to be received successfully. Source: - [Webhook error 413 solution](https://docs.vapi.ai/calls/call-queue-management)

Hi OcultDay69, To set up local webhook testing with Vapi, ensure you're using the

vapi listen

command to forward webhooks to your local development server. Here's a quick guide to get started: 1. **Set up Tunneling**: You'll need a public URL to expose your local server, which

vapi listen

does not provide. Use a tunneling service such as ngrok:

bash
   ngrok http 4242  # Assuming 4242 is your chosen port

2. **Start Vapi Listener**: Forward the webhooks to your app:

bash
   vapi listen --forward-to localhost:3000/webhook

3. **Update Webhook URLs**: Go to your Vapi Dashboard and set your webhook URLs to the URL provided by your tunneling service (e.g.,

https://abc123.ngrok.io

). 4. **Trigger Webhooks**: Initiate webhook events (e.g., make a call) and watch them flow through the tunnel to your server. For a more detailed process, refer to the [local webhook testing guide](https://docs.vapi.ai/cli/webhook). If you experience any issues, ensure your server is running on the specified port, your endpoint path matches your route, and there are no firewall blocks. You can also verify CLI authentication using

vapi auth whoami

. For more advanced configurations or troubleshooting, visit the [custom tools troubleshooting guide](https://docs.vapi.ai/tools/custom-tools-troubleshooting).
