Get profile picture

[Raskelot]

I am making a game with Unity, so far I can get a list of viewers, send message in the chat and receive message. I need to get the profile picture of people in the chat, but here is my code and the error:

WebClient web = new WebClient();
System.IO.Stream stream = web.OpenRead(“https://api.twitch.tv/helix/users?id=39383020”);
using (System.IO.StreamReader reader = new System.IO.StreamReader(stream))
{
string text = reader.ReadToEnd();
Debug.Log(text);
}

Invalid certificate received from server.

This would suggest the the cert bundle, that you have installed with Unity is out of date. And a Unity update or sub module update needs to be installed

A brief google suggests:

• Unity SSL TlsException - Questions & Answers - Unity Discussions
• HttpWebRequest.GetRequestStream() https certificate error exception - Questions & Answers - Unity Discussions
• https://forum.unity.com/threads/ssl-certificate-validation.222529/

This looks like a issue with Unity here rather than Twitch itself?

I am sure it’s all good, but my code is wrong. With the old API, I saw people sending username and oauth from the URL, now I don’t know how to certificate myself to the server.

[BarryCarlyon]

The error you have posted about refers to SSL Certifcations and the fact that Unity is unable to verify the SSL certificate.

Its not oAuth related
