I'm new in Presta. I mostly work with Opencart. But my friend ask to develop payment module for Leasing (loan) using Leasing company API. Module was created... all working fine, but I have one problem.
use SOAP to sent data to leasing company and when return data that order is completed I get this warning (double amount paid) in order view Warning140,36 EUR paid to 70,18 EUR
In real to leasing company was send not double amount...
Where can be problem? If need more info please ask me.
