When customers try to add card details again once their card is expired, we get below error from Clover API when we try to add that card to existing customers.
{ "message": "409 Conflict", "error": { "type": "validation_error", "code": "processing_error", "message": "Customer already has Card on File or ACH on File" } }
We are using the "/customers/<CustomerID>" API endpoint to add a payment method to the customer object. Previously, we were able to add multiple cards, but seems that allows only a single card now.
How do we handle this scenario?
