Please follow the following instructions once.
On the top please add the following code:
Twocheckout::sandbox(false);
Twocheckout::verifySSL(false);
Twocheckout::username('username');
Twocheckout::password('pass');
change the lineitems code bellow:
"lineItems" => array(
array(
"type" => 'product',
"price" => "5.00",
"productId" => "123",
"name" => "Test Product",
"quantity" => "1",
"tangible" => "N",
"startupFee" => "1.00",
"recurrence" => "1 Month",
"description" => "This is a test"
)
),
Hope this will work.
Thanks
