Hi Thomas,
Thanks for reaching out to us. We don’t deal with the Authorization.
Our plugin just uses the API of 2Checkout. The authorization process is done by 2Checkout.
Please contact 2Checkout support regarding your issue. Here you will get some common 2checkout errors: https://shockhosting.net/portal/knowledgebase/18/Common-2Checkout-Errors.html
I think the last point “Authorization Failed: Authorization Failed” matches your situation from the article link above.
Thank You
Failed to authorize: Authorization Failed
