I'm trying to set up an "incoming webhook" in my company. My company have a firewall, and I have to ask to whitlist an IP / range of IP in order to be able to send POST request to the webhook. MS documentation about webhooks connectors: link
The webhook url look like: https://[tenant].webhook.office.com/webhookb2/xxx/IncomingWebhook/xxx/xxx
I have read the office365 documentation about ips: https://docs.microsoft.com/en-us/microsoft-365/enterprise/urls-and-ip-address-ranges
But they are way to many ips. How to find out which ones I should whitelist ? Have any of you ever had this kind of problem?
