 The **OnFeedProviderEnabled** method is invoked when a feed associated with the provider is created by the Widgets Board host. In the implementation of this method, generate a query string with the parameters that will be passed to the URL that provides the feed content, including any necessary authentication tokens. Create an instance of **CustomQueryParametersUpdateOptions**, passing in the **FeedProviderDefinitionId** from the event args that identifies the feed that has been enabled and the query string. Get the default **FeedManager** and call **SetCustomQueryParameters** to register the query string parameters with the Widgets Board.

The method invocation can be used for telemetry purposes or to update the query string parameters or revoke authentication tokens, if needed. If the app only supports a single feed provider or if all feed providers supported by the app have been disabled, then the app can exit in response to this callback.

 **OnCustomQueryParametersRequested** is raised when the Widgets Board determines that the custom query parameters associated with the feed provider need to be refreshed. For example, this method may be raised if the operation to fetch feed content from the remote web service fails. The **FeedProviderDefinitionId** property of the **CustomQueryParametersRequestedArgs** passed into this method specifies the feed for which query string params are being requested. The provider should regenerate the query string and pass it back to the Widgets Board by calling **SetCustomQueryParameters**.
