paypal express checkout return and cancel url not work

[sampathkumara]

Hi

 

Can you kindly help me about paypal express checkout integration.

 

My payment module is oscommerce contribution for paypal express checkout

Also I am using correct API details

 

i have install oscommerce shopping cart and everything work very well and only the problem return URL and Cancel URL not work i mean when customer click confirm the payment or cancel the payment its not returning to my website its cancel url is showing like this (even when he/she does the payment its not returning to my website)

 

http://www.mydomain.com:443/shopping_cart....V68786HC533193H

 

in above URL no any error code just a blank page and if I remove the :443 from url then its returning to shopping cart page so that why I though :443 is the problem. Any idea how :443 adding to URL when retuning from paypal ?

 

 

I have realize that :443 would be the problem any idea ?

 

Please send me email to [email protected] or I am online most of the time.

 

please help me I very appreciating your help

 

 

also Do you know API details of Oscommerce to put in paypal grant permission

 

Best Regards

Sampath
