Some Viddy API endpoints require the developer to authorize with valid user credentials. For this, the developer needs to direct the user to our authentication server which asks for a user's login and password before providing access to the user's information to the application. The user can sign in with his email/facebook/twitter login or create a new account if he/she doesn't have one.
Viddy uses oAuth 2.0 protocol for all API authentication requests. There are two authentication endpoints for the Viddy API. Redirect user to https://www.viddy.com/oauth/authenticate?client_id=<apikey> with the appropriate apikey provided. Once the user is authenticated, the user will be directed to the return_uri provided by the developer when creating the application. The return request will contain the access_token as part of the return URL.
