See the picture above,after I paid with the test account I got at developer.paypal.com,it didn't redirect to my site automatically ,it needs me to click "return to xxx test store" mannually.And if I don't click that ,no data will post back for I fetch data with $_POST,then my site won't know buyer's action.Question :is it the same in the real paypal?If it is the same,then I don't think I can use that method to integrate my site with paypal,could you suggest me a security way to integrate paypal? Update: When I click return to xxx test store manually,a pop window appears,said : Security Warning Although this page is encrypted, the information you have entered is to be sent over an unencrypted connection and could easily be read by a third party. Are you sure you want to continue sending this information? Continue Cancel It would be boring if my customer clicks this every time.
Yeah,I know that,actually My site has already integrated with paypal,it works well in paypal sandbox,but there is some little problems when I test it in sandbox .I want to know if they are the same in sand box and in real paypal?
