Users on WooCommerce can refer to this custom plugin to start setting up GrabPay.

Stripe does not have any official integrations at present that accept GrabPay charges on our other partners such as Shopify, WIX, Xero and OpenCart.

Please check directly with these platforms if they support GrabPay at present, as they may have official plugins or third-party integrations that allow their users to integrate with various payment methods.
