The title pretty much says it all: Does the StackExchange API have a WSDL file to help implement access to the API?
1 Answer
See the API docs; there is no mention of a WSDL file for the API.
Further, WSDL is typically used for old XML and/or SOAP API's. Since the Stack Exchange API is JSON based, it seems unlikely that an official WSDL exists.
(The API docs also make no mention of XML or SOAP.)
