How to set header as token request OAuth by using authentication filter?

I'm developing an OAuth based Web API application. How do I set the header as token I received from OAuth request by using authentication filter?

Reference link: Setting Authorization Header of HttpClient

I'm trying to check all type of methods but it's not working for me:

httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", "Your Oauth token");

context.Request.Headers.Add("Bearer", "Your Oauth token");

My API call source code is:

[BasicAuthenticator]
[HttpGet]   
[Authorize]
public IEnumerable<string> Get()
{
    return new string[] { "value1", "value2" };
}

and I'm getting the response:

{"Message":"Authorization has been denied for this request."}

My token generated code is as below:

public class BasicAuthenticator : Attribute, IAuthenticationFilter
{
    public bool AllowMultiple { get; set; } 
    public Task AuthenticateAsync(HttpAuthenticationContext context, CancellationToken cancellationToken)
    {
        var req = context.Request;
        var reqHeader = context.Request.Headers;
        if (!reqHeader.Contains("Authorization"))
        {
            var pairs = new List<KeyValuePair<string, string>>
            {
                new KeyValuePair<string, string>( "grant_type", "password" ),
                new KeyValuePair<string, string>( "username", "xxxx" ),
                new KeyValuePair<string, string> ( "Password", "xxxx" )
            };
            var content = new FormUrlEncodedContent(pairs);
            var client1 = new HttpClient();
            var response = client1.PostAsync("http://localhost:56672/" + "Token", content).Result;
            var responseBody = response.Content.ReadAsStringAsync();
            var obj = JObject.Parse(responseBody.Result);
            var tokenVal = (string)obj["access_token"];
            client1.DefaultRequestHeaders.Clear();
            client1.DefaultRequestHeaders.Add("Authorization", "Bearer " + tokenVal);
        }

        return Task.FromResult(0);
    }
}

You need to define the Active auth scheme on your API. Try replacing [Authorize] with [Authorize(ActiveAuthenticationSchemes = "Bearer")].
