With FactFinder NG, the SOAP/Webservice-API is no longer an option.To facilitate the switch from SOAP, here is a list of all existing SOAP methods and there replacements for REST- and JSON-API. You can generate a client using the Swagger documentation for REST-API or the JSON-Schema-Definitions, to generate a client for calling these methods.
