We would like to use the REST API via other cloud applications, but our main server is behind a restrictive firewall. Is there a way to access the API in another way? or does the firewall team need to open the port to the world?
P.
Do not open your REST API port “to the world”.
Right, but how can the API be used then? Particularly from another cloud service?
P.
I don’t think that there’s a generic answer that applies to “all cloud services”. Generally you’d want a services internal to your network, that connects outward and talks to “The Cloud™”, rather than having an external service connect inbound.
For ServiceNow, for instance, this is referred to as a MID Server.
