In order to receive API requests from the Smart Carrier platform, you will need to add the following IPs to your firewall/ACL.  Smart Carrier maintains several redundant, geographically-distributed endpoints.  It is highly recommended to add all IPs as the Smart Carrier network will automatically route API requests to your platform from the most responsive location.
