I have a php application , and I’m trying to integrate with paypal payment gateway , my pc is under a fortinet firewall , now i’m struggling with a problem, when i’m trying to make payment with paypal it always retun an error
[L_ERRORCODE0] => 81002
[L_SHORTMESSAGE0] => Unspecified Method
[L_LONGMESSAGE0] => Method Specified is not
but same application and database is copied to another pc which is not under the firewall works fine.
I thinking it’s problem with my firewall.
I had opened 443 port on my firewall , is there anything do more on firewall ?
please anyone can give some adivce?
opening 443 should be enough as https uses port 443. I don’t know in details how paypal api works. is it possible that other ports are involved during the exchange your application – paypal api? try a tcpdump or watch the firewall log in order to see if there are packet exchanges on other ports and so are blocked by the firewall.
