Webhook endpoint

Question asked through support


I’m trying to create a webhook which points to an AWS instance I control. The web interface (https://di------et.pipedrive.com/webhooks) won’t let me specify a URL pointing to a raw IP address, only a DNS name:

http://dig-----et.com/test works
https://dig------et.com/test works
http://dig------et.com:8080/test works
https://di-------et.com:4430/test works fails

Is this just a problem in the web interface?

Is a private IP?
