What IP addresses do I need to add to my firewall?
What IP addresses do you use to send Whatsapp requests to my Inbound or Status webhook URL?
Can I use a firewall and still receive inbound requests from you?
I am not receiving callbacks to my HTTP server. Why might this be?
If you are restricting inbound traffic, including status reports and delivery receipts, please whitelist the following subnets:

188.8.131.52 - 184.108.40.206 (220.127.116.11/28)
18.104.22.168 - 22.214.171.124 (126.96.36.199/28)
188.8.131.52 - 184.108.40.206 (220.127.116.11/28)
