Open Data Protocol (OData) is an open protocol introduced by Microsoft in 2007. It defines a standard way for developing and consuming HTTP-based Web service APIs. This allows users to only focus on the business logic instead of worrying about other RESTful specifications. OData provides the service document that describes how a model constructs and the metadata document that contains a complete description of the feeds, types, properties, relationships exposed by the service. Both documents are defined by using an XML language.

Currently, Datascope Select and Tick History use OData to define HTTP-based REST APIs. The service and metadata documents are available on https://selectapi.datascope.refinitiv.com/restapi/v1. 

This video demonstrates how to use a .NET OData CLI tool to develop a C# application to get a token from an DSS Authentication service. The application uses Visual Studio 2022 and .NET 8.0.
