hello Matt,
I know this is an old thread but my question is directly linked to this one :
After writing the code for the action "addinvoicepayment" using curl (as described in the v3 manual id 134), where should I insert it ? I tried putting it in an empty php page in the modules/gateways/callback dir, with the same name I use for my payment gateway but nothing is happening. What should I do ?
Thank you
Dominique
