The purpose of this Quick Start is to demonstrate an example of one of the DSWS API delivery methods and thus help you discover how to use it.
A DSWS user account (Datastream Child ID and password) is required.
Once your DSWS account has been authorized, data can be retrieved by using the following procedural steps:
The sample quick start code is a simple example that illustrates the basic steps listed above, to authenticate and retrieve some data. It is available for download here.
The first step is to install the zip file in your local folder.
Then double click on Client.App.sln to open the project in Microsoft Visual Studio. Open the two code files.
A DSWS user account (Datastream Child ID and password) is required to run the code successfully. The username format is four letters and three numbers (ZABC123).
Enter your credentials inside the ServiceHelper.cs code, here:
var tokenRequest = new DSGetTokenRequest()
UserName = "", //add your Datastream credentials here
Password = ""
Now you can run the file: click on Start
If you made a mistake with the username or password you will get an error message, otherwise a message will state that a token was successfully retrieved.
Press Enter to continue.
Once the log in details are successful we create a simple request to retrieve the data, specifying the instrument (VOD), data type (PL - the lowest price achieved on the day) and date range. The data is retrieved and displayed, the full output should look like this:
