I am getting this error when members are trying to checkout:
{"name":"AUTHENTICATION_FAILURE","message":"Authentication failed due to invalid authentication credentials or a missing Authorization header.","links":[{"href":"
https://developer.paypal.com/docs/api/overview/#error","rel":"information_link"}]}
They are getting this page after they go through the checkout process:
Payment has not yet been processed
Please try refreshing the page after some time. If nothing happened after a sufficient amount of time, please,
contact us.
The page will be automatically refreshed in 1 seconds
Anyone know what I'm doing wrong?
