Use Orchestrator for interfaces! I personally had some hiccups on how to make the outbound calls with Orchestrator, to consume a REST service from another system, so after extensive research and patience, things went OK! Yes, Orchestrator can save your company a lot of money for interfaces in comparison to BSSV. Business Services still has its place, but Orchestrator is a great alternative! Contact us if you want to save money on converting your existent BSSV to Orchestrator interfaces!
