Hi everyone,

I was just after some advice/general direction about how to integrate to a credit card payment gateway within DNN. The one I need to connect to uses the "hosted" model, ie.

1. I construct and redirect to the bank's URL with the querystring info that their credit card gateway requires.  ( payment amount, merchant id, return url and any other "custom" params I want to provide)
2. The user enters the details into the banks pages and authorises a payment.
3. Bank processes payment and redirects to the URL I supplied as a querystring arg in step1. The querystring will also contain receipt number, transaction outcome and the other "custom" params that I supplied in step 1
4. Back in my DNN site I parse the querystring to determine if the transaction was successful, display receipt number and a nice thankyou ;) Ideally at this point I'd like the user to change from being registered to being a subscriber.

Any ideas as to what the best way to implement this would be . . .

I don't have the option to do server to server transactions nor can I change payment providers.

regards,

Adam.
