Client-Side Setup

Use the Digital Accept Unified Checkout Javascript library to integrate with your e‑commerce site. It has two primary components:

The button widget. It lists the payment options available to the customer.

The payment acceptance screen. It captures payment information from the cardholder. You can set up the payment acceptance screen to be integrated with your webpage or added as a sidebar.
