Hello. I figured out what the problem was. The signature in the "AddAuthenticationToHeaders" method is not quite correct.
For signing, I used this method, which is used in the official SDK from OKEX
private string HmacSHA256(string infoStr, string secret) { byte[] sha256Data = Encoding.UTF8.GetBytes(infoStr); byte[] secretData = Encoding.UTF8.GetBytes(secret); using (var hmacsha256 = new HMACSHA256(secretData)) { byte[] buffer = hmacsha256.ComputeHash(sha256Data); return Convert.ToBase64String(buffer); } }
In the allocated place, I replaced it with my function and everything worked stably.
