I am trying to integrate zoom webhook for webinar end.I have created and activated JWT app for that but when I’m trying to add event notification endpoint url using ngrok It shows URL validation failed error.I have also tried alternative of ngrok and used localtunnel but does not work for me.

I am adding below url in event notification endpoint

1)using ngrok :-

Hi @choksiparth212

Thanks for reaching out to the Zoom Developer Forum, I am happy to help here!  
We recently made some changes to the way we send webhook events to your endpoints.  
Feel free to read our Docs here to learn more about this:

> **[Zoom Developer Docs](https://marketplace.zoom.us/docs/api-reference/webhook-reference/#validate-your-webhook-endpoint)**
>
> The Zoom Developer Platform is an open platform that allows third-party developers to build applications and integrations upon Zoom’s video-first unified communications platform.

Hope this helps,  
Elisa
