In recent months we have set up several openCart websites with PayPal settings. We have found that there are settings that have to be updated when creating them. These settings can be found by logging in to your openCart and going to Extensions > Payments then click edit next to PayPal Standard.
One example of a setting that needs to change is, by default all drop down menus for order status’ are “cancelled”. You have to change it to something else more relevant (and in most cases you don’t want “cancelled”!).
Another setting that should be changed is Transaction Method. It should be changed to “Sale” rather than “Authorization”. This is if you want the funds to be taken from the customer and placed in your PayPal account.
