JavaScript SDK

The JavaScript SDK displays PayPal-supported payment methods on your page to give your buyers a personalized and streamlined checkout experience.

You can use the JavaScript SDK to render buttons, payment method icons (marks), and credit and debit card form fields (card-fields). You can also use the JavaScript SDK to check the funding-eligibility of a given payment method.

Configuration

Configure and customize your integration by passing query and script parameters in the JavaScript SDK script. These parameters personalize your setup and help PayPal decide the optimal funding sources and buttons to show to your buyers.
