<Note>
  Calling this API endpoint triggers an **asynchronous domain verification
  process**. The domain will be temporarily marked as `pending` regardless of
  its current status while the verification is in progress. Since this request
  initiates the complete domain verification cycle, it will trigger
  `domain.updated` webhook events as the domain status changes during the
  verification process.
</Note>

## Path Parameters

<ResendParamField path="domain_id" type="string" required>
  The Domain ID.
</ResendParamField>
