[Question] How to get the parameters returned by the gateway

[damsfx]

In case of a completePurchase call, ho to get parameters return by Monetico!?
The documentation says about a return type MIME plain/text that contains fields separate with a carriage return.

Is it normal that the return value is an empty array??

Lines 8 to 11 in 5198d90

	public function getData()
	{
	return [];
	}

How to get access to cdr, aut or other fields?
