Called to validate that the origin of the request is a registered "client_id", and that the correct credentials for that client are present on the request. If the web application accepts Basic authentication credentials, context.TryGetBasicCredentials(out clientId, out clientSecret) may be called to acquire those values if present in the request header. If the web application accepts "client_id" and "client_secret" as form encoded POST parameters, context.TryGetFormCredentials(out clientId, out clientSecret) may be called to acquire those values if present in the request body. If context.Validated is not called the request will not proceed further.

if your client_id is passed as a form param, you'll have to get it by doing context.TryGetFormCredentials(out clientId, out clientSecret);

if your client_id is passed as an Authorization header, you can get it by doing context.TryGetBasicCredentials(out clientId, out clientSecret);

once you've got the client_id from your request, do context.Validated(clientId), this will set your context.ClientId property, this property will always be null until you've done context.Validated()
