Response Test IPN

Hi !

 

I have a problem with IPN simulator and the listener.

 

The code is good (fully copy from paypal). 

 

When I try the IPN Simulator I get a green light but the response is always INVALID.

 

I use this in sandbox environment. (no production)

 

I need some help 🙂

Thank you in advance !

 

Best Regards,

 

Xav.
