Ustream allows third-party clients to access Ustream users' resources (data) via a HTTP-based (RESTful) API. It also provides a Broadcaster Library that is capable of broadcasting to a user's channel. Both the REST API and the Broadcaster Library uses the OAuth 2.0 protocol for authentication and authorization.
Manage your channels remotely, read and change security settings, branding, video recording, and many more.
Provide a white label broadcasting experience for your users by embedding Ustream's web broadcaster application to your site.
