PHP file_get_contents() failed to open stream error
I am trying to connect to the Amazon Flexible Payments sandbox, and I made a request string as they instruct in their documentation.  Now I am trying to send a request to their service by using the file_get_contents() PHP function, but I get this error:


    [<a href='function.file-get-contents'>function.file-get-contents</a>]: failed to open stream: HTTP request failed! HTTP/1.1 404 Not Found\r\n in file_name.php on line 84

Any idea why that might happen?

Here is the URL I am sending:

    https://authorize.payments-sandbox.amazon.com/cobranded-ui/actions/start?SignatureVersion=2 &returnUrl=http%3A%2F%2Fwww.problemio.com%2Fproject.php%3Fproject_id%2FProject_name%3 &paymentReason=donation&callerReference=YourCallerReference&callerKey=not_shown&transactionAmount=4.0&pipelineName=SingleUse&Signature=not_shown_in_SO%3D%3D
