Integrate payment forms

Use payment forms to allow customers to pay for products and services. These guides use the Rebilly Instruments JavaScript library. To learn about the components of the Rebilly product, see Concepts.

The Rebilly Instruments library processes customer-initiated checkout in the browser, including stored payment cards when the gateway requires CVV. For merchant-initiated transactions, such as subscription rebills and autopay retries, use the Rebilly API. For more information, see Customer-initiated and merchant-initiated transactions.
