PayPal Pro - Security header is not valid

Hi,

Just want to ask, what does this error "Security header is not valid" means? I am in test mode and API credentials are also inputted on the plug in. Do I need to have a live and a test API information?

Hi Gary

That indicate that the account is wrong. Also, please note that PayPal Pro is only available in US, UK and Canada, Australia, so if you are not from one of these countries, you won't be allowed to use PayPal Pro. Maybe that's the actual reason of the error ?

Hi Tuan,

Still having the same error, I have changed and checked the Paypal account and used a server on US to test the PayPal Pro.

Any other advise?
