Hi @userjdr1234 – that error usually means that the Authorization header either doesn’t contain a value, or contains an invalid value. I’d check to see if the correct credentials (client_key and client_secret) are being used in your API calls.
As for that funding-source with the ID ba141fde-c2e6-487a-9a4c-42bdabc79f89, it looks to have been successfully removed.
