Hi Tyson,
Thanks by help!
I have some doubs to create callback.
1. This url should be work to success and failture?
$this->ifSet($options['return_url']);
2. As there is no a order ID, I set clientNumer-date, the problem I should save it somewhere, because the callback resend (orderid, amount, concept, mail, and ID of transaction generated by gateway [also this id should be saved in somewhere]), any suggestion to store this details? or other solution?
$order_id = $this->ifSet($contact_info['client_id']) . "-" . time();
3. When gateway is returned to client/pay/received/gatewayname/id/ dates is captured by validate function? and I should send to success function?
4. OFFTOPIC - I change name of payment gateway from language, but this not is updated to clients? there some cache? if so, how I can clean cache?
Thanks!
Rgds,
Eduardo
