Hello @TuneKey, 

Thank you for posting to the PayPal Merchant Community.

You may need to reach out to your platform to see if there is any additional configuration that needs to be done to enable sandbox testing with PayPal on their platform. If you are still experiencing the issue after that please create an MTS ticket via the following URL:  https://www.paypal.com/mts. This can help us get more details about your website integration and the error being returned. Please ensure that you provide detailed information and any errors you are experiencing when submitting the ticket.

Sincerely,
John
