Help for Aimeos

If you remove these lines, the customer will be sent to the payment gateway even if the total basket value is 0.00 and they must enter their credit card details for example. Most customers will not understand that and cancel the order. Thus, the payment gateway must be skipped if the basket total is 0.00.

The way to go is to skip the payment gateway and redirect the customer directly to the confirmation page while passing the service code so the updateSync() methods of the payment service provider is called. There you can add your code you need but some payment service providers (like PayPal) will throw an error in that case because there's no transaction ID passed and they currently don't ignore that condition.

That makes total sense, thanks for clarifying.

I'll open a pull request with the suggested changes now.
