Seeking Clarification between REST Web Service and a API call
I am trying to explore some new possibilities outside of the normal day to day HL7 interfacing we do. I have only done 1 other Web Service interface but it was using a SOAP proxy wizard. Now I am tasked with trying to make a call to an external API
https://npiregistry.cms.hhs.gov/api/
but I am a bit confused about how to go about doing it. Since they don't have a wsdl, this means it is a REST web service correct? or is it considered an API call? When I read the documentation it feels like it is more geared to building REST services/operations within Ensemble then connecting to one on the outside, am I missing something here.
Can someone help clarify this for me?
Is a API considered a Web Service?
Am I missing something in the Documentation?
Thanks
