The Payment Gateway Interface module enables autoX to integrate with third-party payment gateway providers for payment processing. It supports the full payment lifecycle – from generating a payment link, to checking payment status, to receiving payment confirmation.Use the Payment Link Create outbound webhook to generate a payment invoice and link via the payment gateway. autoX POSTs the order and customer details to the gateway, which returns a payment link (URL) that can be shared with the customer.Use the Payment Status Check outbound webhook to query the payment gateway for the latest transaction status within a given date range. autoX uses this to reconcile payment state against SAP documents.Use the Payment Notification endpoint to receive payment confirmation from the payment gateway into autoX. When a customer completes payment, the gateway calls this endpoint to notify autoX, which updates the payment status on the associated SAP document and triggers the relevant downstream workflow.Use the Payment Link Cancel outbound webhook to expire an active payment link. autoX POSTs a cancellation request to the gateway with the invoice ID and expiry reason, rendering the link invalid.
