Introduction

SumUp Payment Gateway integrates the SumUp inline checkout widget into your Bagisto 2.x store, enabling fast and secure card payments without redirecting customers to an external page.

Key Features:

– Inline SumUp Widget — Customers pay directly on your store using the official SumUp JS SDK—no external redirects.

– Sandbox & Production Modes — Switch environments from the admin panel for easy testing before going live.

– Webhook Support — Asynchronous payment confirmation via SumUp webhooks ensures order status is always accurate, even if the customer closes the browser early.

– Refund Support — Process full and partial refunds directly from the Bagisto Admin Order view. The extension automatically calls the SumUp Refund API.

– Secure Configuration — API keys are stored as password fields in the admin panel.
