Hi all, I am trying to fire a webhook to Make.com out of the VAPI workflow editor. I have dropped in an API Request Module and have made a POST call to my webhook I got out of make.com: https://hook.us1.make.com/arfnjdk5rhjkub23c5rsi3dxvminh71y My workflow won't save and I am getting this error: Save Failed Failed to save workflow: each value in nodes.tool.url must be a valid URL. Hot tip, the protocol should be https://, but found https://hook.us1.make.com/arfnjdk5rhjkub23c5rsi3dxvminh71y I've looked for white spaces at beginning and end but don't see anything. No idea what's wrong! Any help would be greatly appreciated 🙂

Thanks for sharing the error details! To help narrow this down: Are you using the "API Request Node" or the "Tool Node" to configure your webhook call in the workflow? Sometimes using the wrong node type or field can cause URL validation issues, even if the URL looks correct. Let me know which node you’re using, and I can suggest the next troubleshooting step!

I am using API Request Node

Hi Alex, It seems like you have a request related to webhooks or workflows. You can use the

vapi listen

command to debug webhook integrations locally. Here are the basic steps: 1. Use a tunneling service like ngrok to create a public URL:

bash
   ngrok http 4242

2. Start

vapi listen

to forward webhooks to your local server:

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

3. Update your Vapi Dashboard with the ngrok URL for your webhooks. For setting up workflows, although not recommended for new projects, you can refer to the [Workflows quickstart guide](https://docs.vapi.ai/workflows/quickstart) for building and testing workflows. If you need to handle hooks or specific events when a call is involved, the [updated Hook documentation](https://docs.vapi.ai/changelog/2025/7/11) would be beneficial. Let me know if there's anything specific you need help with!
