Checkout error: "The Customer Must Have an Active Payment Source Attached"
If you receive the "customer must have an active payment source attached" error message, this means there is an issue in processing your credit card because the card issuer returned a decline code (i.e. transaction not allowed, insufficient funds, incorrect CVV or expiration date, etc.). Try inputting your credit card information again to ensure it is correct. If you receive the same error message again, try using another card.
Note: To prevent fraud, specific error messages are not always displayed.
