[QUOTE="mrceolla, post: 1180585, member: 109048"] Thank you for your reply. I did find how to list the available providers. I am now typing this URL into Firefox: [URL]http://ipaddress:4322/MPExtended/MediaAccessService/json/GetPlaylists?provider=4[/URL] and receive the following error: {"ExceptionType":"System.Collections.Generic.KeyNotFoundException","Message":"The given key was not present in the dictionary.","StackTrace":" at System.Collections.Generic.Dictionary`2.get_Item(TKey key)\u000d\u000a at MPExtended.PlugIns.MAS.MPMusic.MPMusic.GetPlaylists() in C:\\Users\\Oxan\\Documents\\Projects\\MPExtended\\PlugIns\\MPExtended.PlugIns.MAS.MPMusic\\MPMusic.cs:line 504\u000d\u000a at MPExtended.Services.MediaAccessService.MediaAccessService.GetPlaylists(Nullable`1 provider) in C:\\Users\\Oxan\\Documents\\Projects\\MPExtended\\Services\\MPExtended.Services.MediaAccessService\\MediaAccessService.cs:line 820\u000d\u000a at SyncInvokeGetPlaylists(Object , Object[] , Object[] )\u000d\u000a at System.ServiceModel.Dispatcher.SyncMethodInvoker.Invoke(Object instance, Object[] inputs, Object[]& outputs)\u000d\u000a at System.ServiceModel.Dispatcher.DispatchOperationRuntime.InvokeBegin(MessageRpc& rpc)\u000d\u000a at System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage5(MessageRpc& rpc)\u000d\u000a at System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage41(MessageRpc& rpc)\u000d\u000a at System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage4(MessageRpc& rpc)\u000d\u000a at System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage31(MessageRpc& rpc)\u000d\u000a at System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage3(MessageRpc& rpc)\u000d\u000a at System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage2(MessageRpc& rpc)\u000d\u000a at System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage11(MessageRpc& rpc)\u000d\u000a at System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage1(MessageRpc& rpc)\u000d\u000a at System.ServiceModel.Dispatcher.MessageRpc.Process(Boolean isOperationContextSet)"} Any idea why I am getting this error? I am trying to use this command to get the IDs of my playlists since I don't know what they are. I'm hoping once I have that information that I'll be able to load this playlist via MPExtended or WiFi remote. Is this possible? I can trigger play via IR if needed so I'm not worried about that right now. I'm just trying to programmatically load a playlist. Are simple HTTP GET commands enough to accomplish this or will I need to write my own application? I'm trying to interface HomeSeer 3 with MediaPortal for a few simple tasks, such as this one.
