Payment Gateway

Hello!

I am about to begin to program a Payment gateway with Yii. Do you have any experience or any advise to give me? I don’t have the documentation yet, but I guess I’ll use the cURL Yii extension to send POST data to the bank…

If anyone can give me any advise, I’ll be grateful, thank you!!!

Of course, I’m not programming the payment gateway itself, but I want to make payments using one that already exists. Anyway, thanks for the answer.
