Errors after changing Authorize.net accounts

When you change the Authorize.net account connected to your store, all existing cards and CIM profiles will no longer be valid on the new account. This is expected behavior, as customer information cannot be copied between Authorize.net accounts for any reason. The data must instead be created anew and re-validated.

If you must change Authorize.net accounts, any customers with existing payment data on your store may experience "Unable to load payment data." errors at checkout.

To prevent or fix these errors, disable all stored cards from prior to the account switch by running this SQL query on your Magento database:

UPDATE paradoxlabs_stored_card SET active=0 WHERE created_at < '2023-06-31';

Change the date in the example to the date you changed the Authorize.net account.
