Hello,
When i activate the paypal v2.0 on my funnel, i have this message “Security header is not valid” when i try to pay with paypal.
I installed the gateway as explain in the tuto.
Do you have an idea ?
Thank you

Hi @omppp,
That error means that your ApiKey, Signature or Password fields are wrong, perhaps you added an extra space unnoticed 
double check it and let me know if that’s not the case 
You are right, one space was take place in the code
