Hello, I am new for authorize.net platform. I have downloaded php sdk from authorize.net Github forum. When I use this sdk on my web site, I didn't use composer. I just copied and pasted and used these lines for usage this sdk.
require getcwd() . '/sdk-php-master/autoload.php';use net\authorize\api\contract\v1 as AnetAPI;
use net\authorize\api\controller as AnetController;
But I got 404 error when I call
$merchantAuthentication = new AnetAPI\MerchantAuthenticationType();
How can I resolve this issue? I don't want to use composer. Please help me. Thank you.
