That depends entirely on how the API expects you to pass the credentials. Since we don't know which API you're calling, we have no idea how they expect you to pass the credentials. Consult their documentation, or contact their support team.

For "Basic" authentication, you just need to set the appropriate header, as shown in this SO thread[^]:

C#

var encoding = System.Text.Encoding.GetEncoding("ISO-8859-1");
byte[] headerBytes = encoding.GetBytes(username + ":" + password);
string headerValue = Convert.ToBase64String(headerBytes);
req.Headers.Add("Authorization", "Basic " + encoded);

Basic authentication scheme | HTTP authentication - HTTP | MDN[^]
