Hallo,
Ik heb voor het upgraden van packages een Paypal API.
Werkt gewoon tot toebehoren. Alleen als op de pagina komt na de betaling (Return URL) krijg ik een error, maar de package wordt wel toegevoegd. Hoe zorg ik dat die error verdwijnt?
Code
Error : This transaction cannot be processed. The amount to be charged is zero.
