FQDN and Fixed IP on HubSpot Webhook

[Jdravet]

Hello, I'm trying to create a workflow that uses webhooks (or custom code to call an API).

The particularity of this API is that it comes from my client. It is an internally developed service. Access security is very important. They want me to provide the HubSpot IP address of the host that will make the requests. As I understand it, HubSpot uses dynamic IPs, so I told them it wasn't possible. They then asked if HubSpot has an FQDN for outbound requests.

I would like to know what the FQDN is for requests originating from HubSpot via webhooks (or from custom code) in a workflow. If there isn't one, I'm open to security ideas that do not require my client to use a third-party system. Thank you in advance.

PS: For your information, we have tried .hubspot.com and it doesn't work.

Hey @Jdravet this isn't possible at the moment, and is unlikely to happen in the near future. Webhooks are very much a push or pull service. So the workflow will either push information to a source or pull from a source. 

It sounds like webhooks isn't going to be suitable for your needs. However, you can do everything with your own scripting using the HubSpot apis, all endpoint urls are available here. You can pull whatever available data you need from these endpoints and the URLs will not change without notice.
