Callback Services are HTTP requests that are made from the Vibes platform to a Customer's URL endpoint, for the event based delivery of information.
Callback Services can originate from either of Vibes' two Data Centers. If a customer wishes to whitelist the IP traffic to their endpoint, they should include the following Originating IP addresses in their rules:
|Data Center||IP Address|
|Elk Grove (Chicago)||188.8.131.52/32|
