Comskip and Media Segments

[AustinL]

I am making good progress with this project.  I can use the API to enumerate media segments for an item and I can delete media segments (if the Media Segments API plugin is installed on my server)... But I am having a real problem creating media segments.  The URL I am posting to is

http://myserver/MediaSegmentsApi/{itemId}

Where {itemId} is the ID of the parent item, and the request body is something like this:

{
"Id":"baaac615-a238-4cf2-8dcc-fb22afce9782",
"ItemId":"5a7af56b-eec6-f219-6cd0-d445b5bc87ad",
"Type":1,
"StartTicks":123527,
"EndTicks":345475
}

But... the API is expecting a URL parameter called providerId and I have absolutely no idea what this is - if I use a random string, I get the response:

{
    "message": "Provider with id 'RandomString' not found."
}

Any ideas? - What is a "provider" in this context, and how do I get an ID for it?

Thanks,
Austin
