    SetExpressCheckout API call failed.
    Detailed Error Message: Security header is not valid
    Short Error Message:
    Error Severity Code: Error

    Getting this error message when clicking the book via paypal button on Pro Extended. I’ve put in API credentials. Do you have any idea how I can fix this?

    Cheers,
    Bryn
