payment

Hi everyone,

Is there any module to provide integration between payment.

Scenario is like this:
I wanna enable the website1 to pay for fees (registration fee) at website2 through nbepay. It's because website1 is not likely to use this payment features frequently, whereas website2 is going to use it, always.
During the payment process, website1 and website2 are going to validate an value to validate that the payment is coming from website1.

Hence I'm finding out is there any solution for this matter?

Thanks
