-  - If you attempt to create ([POST /domains/{domainId}/records](/api/v4/domains-domain-id-records/#post)) or update ([PUT /domains/{domainId}/records/{recordId}](/api/v4/domains-domain-id-records-record-id/#put)) a Domain Record of `type` `CNAME`, `A`, `AAA`, or `MX` with a `name` value that already exists, you will receive an error message indicating that the name already exists.
-
 - When attempting to stage a PayPal payment ([POST /account/payments/paypal/execute](/api/v4/account-payments-paypal-execute/#post)) on an account that has been flagged for no charge, you will receive the following error message, `This account cannot be charged`.
