This sample uses the excellent DevDefined OAuth .Net Implementation along with the Justin.TV rest apis for working with streaming and archived video.

Here’s some sample .net code to create a channel and user in justin.tv. The OAuthRequest wrapping class is then presented which acts as a core facade to justin.tv apis which secures the calls via a direct 2-legged request.

You should be able to modify the OAuthRequest and sample code for any OAuth based rest api as required.

Sample code to create new channel and user

// create new OAuthRequest and session
var oauthRequest = new OAuthRequest();
var oauthSession = oauthRequest.CreateSession();

// build up thepost  request
oauthSession.WithFormParameters(
	new
	{
		login = "[LOGIN]",
		password = "[PASSWORD]",
		birthday = "[DATEOFBIRTH]",
		email = "[EMAIL]",
		category = "[CATEGORY]",
		subcategory = "[SUBCATEGORY]",
		title = "[TITLE]",
		publisher_guard = "[PUBLISHER_GUARD]"
	}
);

// make the post request get the response as xml
HttpWebResponse results = oauthSession.Request().Post().ForUrl("http://api.justin.tv/api/channel/create.xml").ToWebResponse();
XDocument xdoc =oauthRequest.GetWebResponseAsXml(results);

// continue processing...
