In sandbox, I am trying to confirm a payment returned via Javascript CHECKOUT SDK and I am getting this error: HTTP/1.1 401 Unauthorized Cache-Control: max-age=0, no-cache, no-store, must-revalidate Content-Length: 244 Content-Type: application/json Date: Tue, 25 Feb 2020 21:12:21 GMT Paypal-Debug-Id: 63c8a5f2a7393 {"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"}]} Ccording to https://www.paypal-community.com/t5/Sandbox-Environment/quot-Authorization-failed-due-to-insufficient-permissions-quot/td-p/1794523 I should just create a new APP. I did it but the error persists. Nobody at Paypal support from Brazil seems to know what I am talking about. Any ideas? Thanks.
