How do I authenticate to the GoDaddy API using C#?

Question

I have setup an account on GoDaddy and have my developer keys for accessing the API. Using Fiddler I am able to construct a request that returns results. However, using the following code from a Console application fails with "Unauthorized". I'm using the same address and keys in both places.

What am I missing?

        using (var client = new HttpClient())
        {
            client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Authorization", "sso-key VUjHMntw_UyosKRMGaLXE4e3E1h29Xx:DSqM2jiJcRyXvSbLehjYUZ");

            HttpResponseMessage response = await client.GetAsync("https://api.ote-godaddy.com/v1/domains/available?domain=google.com");

            if (response.IsSuccessStatusCode)
            {
                var result = await response.Content.ReadAsAsync<string>();
                Console.WriteLine(result);
            }
            else
            {
                Console.WriteLine(response.ReasonPhrase);
            }
        }

NOTE: The authorization key and secret have been modified.

The following is what I do in Fiddler that works:

I'm fairly certain you're sending the auth header as:

Authorization: Authorization sso-key VUjHMntw_UyosKRMGaLXE4e3E1h29Xx:DSqM2jiJcRyXvSbLehjYUZ

Try this instead:

client.DefaultRequestHeaders.Authorization = 
    new System.Net.Http.Headers.AuthenticationHeaderValue("sso-key", "VUjHMntw_UyosKRMGaLXE4e3E1h29Xx:DSqM2jiJcRyXvSbLehjYUZ");

The Authorization: prefix is assigned for you by the method call.

Thank you!! Also this king of thing doen't work too: new AuthenticationHeaderValue($"sso-key {key}:{secret}"); – Ernest Rutherford Feb 28 '21 at 12:31

That particular call does not require authentication. This should work for you.

    static void Main(string[] args)
    {
        TestDomain().Wait();
    }

    public static async Task<string> TestDomain()
    {

        using (var client = new HttpClient())
        {
            //client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Authorization", "sso-key VUjHMntw_UyosKRMGaLXE4e3E1h29Xx:DSqM2jiJcRyXvSbLehjYUZ");

            HttpResponseMessage response = await client.GetAsync("https://api.ote-godaddy.com/v1/domains/available?domain=google.com");

            if (response.IsSuccessStatusCode)
            {
                var result = await response.Content.ReadAsStringAsync();
                Console.WriteLine(result);

                return result;
            }
            else
            {
                Console.WriteLine(response.ReasonPhrase);

                return response.ReasonPhrase;

            }
        }

    }

That is correct. I should have used a different api call to demonstrate the problem. — DarLom, Apr 08 '16 at 14:58
