**API Endpoint(s) and/or Zoom API Event(s)** **[Webhook verification](https://developers.zoom.us/docs/api/rest/webhook-reference/)** **Description** So I was trying to set up a webhook to my django application inside my docker container. I was also using ngrok to create a public URL to connect to my docker instance. When I reach the [verification](https://developers.zoom.us/docs/api/rest/webhook-reference/) step, and try to verify the url, I keep getting the error `URL validation failed. Try again later`. When I check the ngrok instance, I don’t see any requests coming in. Just to confirm that ngrok was working, I used postman to create a post request and was able to see my own request come in. As another option, I tried using my staging environment to test the verification process as well, and still had the same error. **Error message** URL validation failed. Try again later. **How To Reproduce** _Steps to reproduce the behavior:_ _1. Create a new endpoint for receiving zoom webhooks_ _2. Start a backend API inside a docker container_ _3. Start a ngrok instance exposing the local docker image port_ _4. On zoom dashboard, try to verify the webhook URL_ _5. See that the error on Zoom dashboard_ ---

Start a backend API inside a docker container_ _4. Start a ngrok instance exposing the local docker image port_ _5. On zoom dashboard, try to verify the webhook URL_ _6.

Hello @gianni.zoom, I’m encountering the identical error message: **“URL validation failed. Try again later.”** I’ve set up a legacy app and configured a few event subscriptions. I’m attempting to test the events locally using ngrok as the Event notification endpoint URL. However, the URL validation is unsuccessful, and I’m also experiencing a **403 Forbidden** error for the subscribed events. Would you mind assisting me in getting started? Your help is much appreciated. Thank you! ---
