There are several solutions you can use if you prefer a payment provider that is not yet supported by Ecwid.
Use Authorize.Net SIM emulation
You can configure a custom payment method using the Authorize.Net SIM emulation as long as the payment provider can emulate the work of Authorize. If you are not sure about this, we advise checking it with the payment provider support team directly.
Create a custom integration
You can connect your Ecwid store with the payment provider of your choice by building a custom integration based the Ecwid Payment API. You can develop the solution yourself or hire a third-party professional for this task.
