Grand Central Web Service – The Link to WM Datenservice.
The Grand Central Web Service is an interface for client applications to access financial instrument data stored in the Grand Central Data Warehouse (e. g. all data from WM Datenservice), over an Internet or Intranet connection. It provides an easy way to implement financial interfaces without the necessity of writing SQL database queries.
A simple query mechanism is provided by the API to request values for a desired range of instruments and data fields. Based on ASP.NET, it supports open standards and protocols such as HTTP, SOAP, XML, and WSDL, making it interoperable with any programming language or operating system that supports communication over the web.
WSDL makes it easy for developers to generate code proxies for their language of preference to interact with the web service. A broad range of clients, including browsers and mobile applications, are supported under Windows, Linux, Android, and IOS.
