Buyer interaction. Your application uses a browser for buyer approval or authentication when PayPal requests it. Configure the merchant return and cancel URLs for this flow.

Create a USD 30 digital order from a trusted cart. Store the order ID and redirect the buyer to the payer-action link. After approval, capture this same order from your merchant application.
