Problems setting paypal express integration

[tomerp]

Hello all,

I was trying to set up paypal express into my website, and for the integration I need to provide my client ID and secret code.

I created new app from this page: https://developer.paypal.com/developer/applications under my apps and credentials and got both client ID and secret code from there and pasted it at the website integration but it didn't work. hope someone could understand why it didn't work. 

Thanks
