This section of the docs describes how to add embedded payment forms to your website. These guides use the Cashier and Rebilly Instruments JavaScript libraries. To learn about the components of the Rebilly product, see Concepts.
Rebilly Instruments and Cashier libraries process customer-initiated flows 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.
