Once redirected, the API caller has 6 hours for the payer to approve the order and either authorize or capture the order. If you are not using the PayPal JavaScript SDK to initiate PayPal Checkout (in context) ensure that you include `application_context.return_url` is specified or you will get "We're sorry, Things don't appear to be working at the moment" after the payer approves the payment. | getLinks(): ?array | setLinks(?array links): void |
