Estou tentando usar este exemplo , aonde eu pego o {"grant_type": "client_credentials"} ?
$file = file_get_contents("./config.json");
$config = json_decode($file, true);
$environment = ($config["sandbox"] === true) ? "development" : "production";
$certfile = "./certificate/" . $config[$environment]["certificate_name"];
$curl = curl_init();
$authorization = base64_encode($config[$environment]["client_id"] . ":" . $config[$environment]["client_secret"]);
curl_setopt_array($curl, array(
CURLOPT_URL => $config[$environment]["pix_auth_url"], // Rota base, desenvolvimento ou produção
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 0,
CURLOPT_FOLLOWLOCATION => true,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "POST",
CURLOPT_POSTFIELDS => json_encode("{"grant_type": "client_credentials"}"),
CURLOPT_SSLCERT => $certfile, // Caminho do certificado
CURLOPT_SSLCERTPASSWD => "",
CURLOPT_HTTPHEADER => array(
"Authorization: Basic $authorization",
"Content-Type: application/json"
),
));
$response = curl_exec($curl);
curl_close($curl);
echo "
";";
echo $response;
echo "
