We are setting up security between our backend service and our Apigee API Proxy. My company will not allow opening our backend API to the entire internet, so we want to use two way SSL and but also set up a range of ip addresses that our backend will accept requests from.
Yes, this can be done, but the IP addresses are different for each customer/organization. Open a ticket in your support portal and we’ll be happy to help.
Note that you can only do this for a paid organization, not a developer (free) organization. There is no guarantee that free org message processor IP addresses will stay the same.
