Twitter is fighting off a DoS attack when I finally get my code working. Such is life.
I have been working on using cURL to send POST data to PayPal for almost two weeks now. Everything I tried seemed to send me to the PayPal homepage, without explanation.
My tweets have been full of anger towards PayPal/cURL/PHP because of it. When I finally have some success, Twitter is not there for me.
Keep fighting the good fight Twitter.
