To transfer out a NL domain you're going to need an authcode. You can request the authcode in the Domain Manager or through API.
To obtain the authcode through the Domain Manager:
- Log in the Domain manager and go to 'Domains'
- Lookup the domain you want to retrieve the authcode for
- The authcode is shown on the domain detail page as shown below
Once you've obtained the authcode, initiate the transfer with the new registrar and the transfer will complete realtime.
