Extension Chat Message returns 401 authentication failed

[BarryCarlyon]

You need to cast the channelID as a string not a number

@BarryCarlyon

However

$payload = array(
    'exp' => time() + 60,
    'user_id' => '15185913',
    'role' => 'external'
);

Also works (my user_id and I own the extension posting to another channel)

So

const sigChatPayload = {
    "exp": Math.floor(new Date().getTime() / 1000) + 4,
    "user_id": "123123",
    "role": "external"
}
const sigChat = jwt.sign(sigChatPayload, ext_secret);

// We have now prepared the Signature and data

got({
    url: "https://api.twitch.tv/helix/extensions/chat",
    method: "POST",
    headers: {
        "Client-ID": config.client_id,
        "Authorization": "Bearer " + sigChat
    },
    json: {
        broadcaster_id: "321321",
        text: "This is a Test Message Kappa",
        extension_id: config.client_id,
        extension_version: config.extension_version
    },
    responseType: 'json'
})

Also

@tejendrapratap12

app.post("/getJWTToken", (req, res) => {
  let data = {
    channel_id: 768266494,
    role: "external",
  };

  const token = jsonwebtoken.sign(data, secret);
  res.send(token);
});

This seems dangerous. It looks like you are intending to leak generated JWT’s which is potentially dangerous to do so.
