-Log in
-Visit 'My Account' > 'Profile'
-Click 'API Access' link (listed under Account Information)
-Click option 2 : 'Request API credentials'

-Enter these details into your mysite/_config.php file with either the set_config_details or set_test_config_details functions
Notes / Troubleshooting:
 -you must be logged into sandbox to process a test payment.


Add the following to your mysite/_config.php, and populate values with the appropriate information from your Paypal account:


if(Director::isDev() || Director::isTest()){
	PayPalExpressCheckoutPayment::set_test_config("TestPaypalAPIUsername","TestPaypalAPIPassword","TestPaypalSignature");
}
elseif(Director::isLive()){
	PayPalExpressCheckoutPayment::set_live_config("PaypalAPIUsername","PaypalAPIPassword","PaypalSignature",false);
}
