Went into woocommerce. Tried to setup payment. Saw the paypal identity token. There is the ? to hint you where you can get it but after finding here and there and even googling it seems like its a bit hard to find. Looked like you need to create a business paypal account in order to get the paypal identity token. There is also the api. I found this resource pretty helpful.
I am using woocommerce so
Under Shopp → Settings → Payments → PayPal Standard, enable Order Verification
didn’t really apply to me and all the below.
My return url was arevainna.com/shop
