Register your application
To use Custom Decision Service for your application, register it on the portal. This article explains how.
Go to the front page of Custom Decision Service. On the ribbon, click My Portal, as highlighted in the image:
If you are not already signed in, the portal prompts you to sign in with your Microsoft account. After you have signed in, the portal displays your Microsoft account in the upper-right corner of the page.
To register your application, click the New App button.
In the dialog box, choose an App ID for your application. Custom Decision Service requires a unique ID for each application. If someone else has already taken this ID, the system asks you to pick a different one.
Specify an Action Set API. This setting is an RSS or Atom feed that communicates the available content for your application to Custom Decision Service. Enter a name for the feed, and enter the URL from which it is served. To do this step later, click the Feeds button and then click the New feed button. An example that creates an RSS feed is described later.
To register your application, select the Custom App check box in the lower-left corner. Enter a connection string for the Azure storage account where your application data is logged. For more information on how to create a storage account, see How to create, manage, or delete a storage account.
