Question about 3rd party gateway variable and return

Hi All,

I have 2 questions here.

1. I see there is a $amount and $fee variable defined in the callback demo file. Whats the different? The gateway only return the total_fee.

2. I am working on Alipay cross border gateway. Their return method only for returning to the page, not providing a secure method to validate the payment. To validate the payment. It require another file for notify.

WHMCS only accept 1 file callback.php. What should I do?

Hi

1. Every gateway has its own callback variables. You have to adapt the script to work with them. Anyway let's say that I'm paying 10 euro with PayPal. It has a fee of 0.35 euro + 3.4%. The result will be $amount = 10 euro and $fee = 0.69 euro. That's it.

2. I did not understand perfectly what you mean. Anyway you should just point to your callback file. If $status is true the client will be redirected to your "OK page". On the contrary if it's false he'll go to "KO page".
