IANA's "SOAP Service Port" — a name reservation, not a protocol anyone standardised on.
7627 is registered as soap-http, "SOAP Service Port", to an individual assignee with no accompanying specification. SOAP itself is a W3C messaging format carried over ordinary HTTP, so real SOAP endpoints live on 80, 443, 8080 or whatever port their application server uses — almost never here. Nmap sees 7627 open on about 0.04% of scanned hosts. Treat a listener as an HTTP service until proven otherwise and read its response.
Expose with care
SOAP endpoints commonly expose a WSDL that enumerates every operation, and enterprise SOAP APIs often authenticate weakly or not at all; keep them behind a gateway.
