How It Works
- Customer selects PayPlug at checkout and clicks "Place Order"
- The addon creates a payment via the PayPlug REST API (POST /v1/payments)
- Customer is redirected to the PayPlug hosted payment page (or inline form appears on checkout page)
- Customer enters their card details and completes the payment
- Customer is redirected back to your store; the addon verifies the payment status
- PayPlug sends an IPN notification for reliable server-side confirmation
