c# - GetAsync using Basic Authentication even though I specify Bearer

Question

I have the below GetAsync which I'm trying to authenticate with a bearer token but I get a 403 response. When I look at the request headers I can see Authorization: Basic YWJjOmRlZg==

var client = new HttpClient(handler)
{
    BaseAddress = new Uri("https://api.myendpoint.com/v2/")
};
client.DefaultRequestHeaders.Authorization =
                new AuthenticationHeaderValue("Bearer", "token");
var httpResponseMessage = _myclient.GetAsync("instruments?country=US&type=BOND").GetAwaiter().GetResult();

The token is valid. I confirmed that with Postman. I also hardcoded it into AuthenticationHeaderValue to ensure I had the correct token. I guess I assumed I was passing the bearer token incorrectly.

How do I get it to use Bearer authentication?

Answer 1

Passing token to header (I am currently using this):

client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token);

or something like this:

client.DefaultRequestHeaders.Add("Authorization", "Bearer " + token);
