I signed into manager.paypal.com
with the same credentials, but can't seem to successfully connect with curl. (https://developer.paypal.com/docs/classic/payflow/gs_payflow/).
curl -s https://pilot-payflowpro.paypal.com -d 'ACCT=5105105105105100&
AMT=1.00&EXPDATE=1216&TENDER=C&TRXTYPE=S&
PARTNER=PayPal&
PWD=***********&
USER=********&
VENDOR=*********'
However I get back an error.
RESULT=1&RESPMSG=User authentication failed
The only issue I can think of is that the password includes encoded characters (an exclamation point) but I'm using Ruby to parameterize the curl shell command so it should be encoded properly.
