Hello,

I am trying to get an authorization code from within the Laravel-based app. I am getting “Bad Request - 400” error.

```auto
$response = $response = Http::withHeaders([
            "Authorization" => "Basic ".base64_encode('Client ID:Client Secret'),
            "Content-Type" => "application/x-www-form-urlencoded"
        ])->post('https://zoom.us/oauth/token', [
            "grant_type" => "authorization_code",
            "code" => $_GET['code'],
            "redirect_uri" => "https://app.app.com/oauth/success",
        ]);

dd($response->getBody()->getContents())

```

Response below:

```auto
"{"reason":"unsupported grant type","error":"unsupported_grant_type"}"

```

I also noticed that the error remains as is even if the client id and client secret are incorrect.

Can someone please point me in the direction of how to rectify this?

Thanks a lot for the help.

Hi @epzoom
