Twilio post sms using HttpClient

Question

I'm trying to post data to the Twilio Rest API to trigger a sms sendout.

I've tryed to do what is instructed to do with cURL but with HTTP Post insted.

https://AccountSID:AuthToken@api.twilio.com/2010-04-01/Accounts/AccountSID/Messages

Then in the body I post data looking like this:

public class TwilioMessage
{
    public string To { get; set; }
    public string From { get; set; }
    public string Body { get; set; }
}

I'm getting StatusCode: 401, ReasonPhrase: 'UNAUTHORIZED' all the time. What am I missing here?

Twilio evangelist here.

Instead of including your credentials in the URL you should set them using the DefaultRequestHeaders property:

var byteArray = Encoding.ASCII.GetBytes("username:password1234");
client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Basic", Convert.ToBase64String(byteArray));

Hope that helps.
