    I don't see any issues with your configuration. Usually, the error is because of the extra spaces/characters in the API credentials but your keys are fine as far as I could see it. 

    Can you check your Paypal account if you have been approved for Express checkout payments? I would suggest reaching Paypal about this too. If you Paypal express is not yet activated, you can activate it here: https://www.paypal.com/US/webapps/mpp/express-checkout

    Please get back to us if you need further assistance.
