I am trying to get paypal transaction transaction information that is transmitted to our website when a client is redirected to our website.
I enabled auto-return and pdt in my paybox account settings. I sent the sample transaction to paypal and it responded to my tx app url.
As shown in some docs, I did curl req for https://www.paypal.com/cgi-bin/webscr and tried to get the information by passing req values as follows:
a.) tx = same one received from paypal
b.) at = pdt code given by paypal while turning pdt on
c.) cmd= "_notify-synch"
but as a result I get String (0) "".
What am I missing?
