I found 3 files in the /ssl/certs/ folder
and 2 files in the /ssl/keys/ folders
but cannot find a cacert.pem file.

where is the cacert.pem file located in a standard install of cPanel?

Hi i am getting the following error
array(4) { ["client_secret"]=> string(42) "sk_test_xZZKjDRsPZb0z3KWvOCK0uXf00amK9apPF" ["grant_type"]=> NULL ["client_id"]=> string(35) "ca_HFVybE89S1Jse3hapX45PqAMaCFfI3Mr" ["code"]=> string(35) "ac_HJKaA5JoCzOwofYAxd0OYkYA4qodf78y" } array(2) { ["error"]=> string(15) "invalid_request" ["error_description"]=> string(23) "No grant type specified" }

API_KEY, 'grant_type' => $_GET['authorization_code'], 'client_id' => CLIENT_ID, 'code' => $code, ); var_dump($token_request_body); $req = curl_init(TOKEN_URI); curl_setopt($req, CURLOPT_RETURNTRANSFER, true); curl_setopt($req, CURLOPT_POST, true ); curl_setopt($req, CURLOPT_POSTFIELDS, http_build_query($token_request_body)); // TODO: Additional error handling $resp = json_decode(curl_exec($req), true); $respCode = curl_getinfo($req, CURLINFO_HTTP_CODE); curl_close($req); echo $resp['access_token']; var_dump($resp); } else if (isset($_GET['error'])) { // Error echo $_GET['error_description']; } else { // Show OAuth link $authorize_request_body = array( 'response_type' => 'code', 'scope' => 'read_write', 'client_id' => CLIENT_ID ); $url = AUTHORIZE_URI .
