payment module development documentation

Hi,

Is there any documentation available on how to implement a payment module extension?

Thanks!

check: https://www.nopcommerce.com/boards/t/2891/how-to-code-my-own-payment-method.aspx

OK, thanks

Just one question: is there an equivalent of CheckoutCompleted.aspx incase something has gone wrong on the PSP side?

ie. something like CheckOutError.aspx where I can show an Exception Message?

I understand I can easily make my own page, but this seems like a generic problem to me, so maybe a generic status page would be nice?

Thanks!

No, each payment gateway has its own return (success or error) pages. A generic page is not possible because a parsing/processing of error messages is specific for each payment gateway

yeah, in retrospect that sounds absolutely logical, thanks!
