We are receiving an error when calling the Checkout endpoint.
A browser pop-up appears: “An error prevented the payment form from opening. Please contact the organization directly to arrange payment.” After you OK on the alert popup, the javascript console emits this message, which comes right from the bbCheckout js file: "An error occurred calling the Checkout endpoint. The endpoint returned a status of 401 (Unauthorized). The response was: You do not have permission to view this directory or page." It also gives an error code of 1005.
This error is only happening for one account - this account has confirmed that their Payments API setup is configured correctly.
We need urgent assistance on this issue.
