Is it just me or is the get payment data API down? I can't get it to work! I tried testing it out in a browser (separately from my application, in this link: https://developer.visa.com/capabilities/visa_checkout/reference#visa_checkout__get_payment_data_api) and got the response pictured above.
When I try to run my own application using the code below I get a 401 Apikey not present 9206 error.
