I developed a payment gateway with paypal and php with this SDK https://paypal.github.io/PayPal-PHP-SDK/ On my website implementation when buyer click on checkout he redirected to paypal for payment (sandbox for now) and he can see a paypal page with a next button, when buyer click con next button he redirected to my site in the url specified on $redirectUrls->setReturnUrl('myurl') but in some examples I've seen for "Paypal Button Payment" the buyer must be accept the payment before he redirect to the website. Am I doing something wrong?
