PayPal Fetch Token -

I am using the PayPal API for Express Checkout Integration. I installed Express Checkout, one with one token Gets on the page, like this page:

  https://api-3t.sandbox.paypal.com/nvp  

token and more Or less that looks like

  ACK = failure & amp; L_ERRORCODE0 = 81,002 & amp; L_SHORTMESSAGE0 = unspecified% 20Method & amp; L_LONGMESSAGE0 = Method% 20Specified% 20is% 20not% 20Supported & amp; L_SEVERITYCODE0 = Error  

My question is: How do I get it through PHP? I do not have to redirect from the page in advance, how do I just bring the contents of a remote file after passing some post parameters in advance?

Thank you!

I do not have a direct answer, but to get the quick answer for PayPal, the developer forum is really Good, especially when its specific technology (.NET, PHP etc)
