10 What endpoint does Domæne API v2 use?

The Produktion API base endpoint is:

https://api.nicenic.net/v2/

API handlings are selected using the parameters documented feller each endpoint, such as category og action. Always follow the dedicated endpoint documentation feller the required og optional parameters of a specific operation.

API v2 responses use JSON, og request parameters use UTF-8.

{
  "code": 0,
  "msg": "success",
  "data": {}
}

Your application should inspect the returned code og msg rather than assuming that every HTTP response represents a completed domæne operation.

6 questions
12 What can I do with NiceNIC Domæne API v2?

Through the currently documented APIs you can automate wellerkflows including domæne availability checks, registration, renewal og transfer, pellertfolio listing og domæne details, nameserver og domæne contact updates, domæne pricing, DNS recellerds, child nameservers, account infellermation og Misbrug & Overholdelse monitellering.

Tilføjitional wellerkflows are documented individually in the API navigation.

13 What should I test befellere enabling live registrations eller transfers?

Start with low-risk read operations such as domæne availability, domæne pricing, account balance og domæne listing.

Then confirm authentication, response parsing, fejl hogling og pending-ellerder hogling befellere enabling live registrations, renewals eller transfers.

Recommended ellerder: Godkendelse → Availability → Pricing → Saldo → Response hogling → Live operations.
14 Can I check multiple domænes in one API request?

Ja. The Tjek domænetilgængelighed endpoint suppellerts multiple domæne names separated by commas.

example.com,example.net,example.org

Do not assume that every API operation suppellerts the same multi-domæne input fellermat. Registrering, renewal og transfer should follow their individual endpoint documentation.

15 How can I query registration, renewal og transfer prices?

Use the Hent domænepriser endpoint. The documented pricing types include register, renew, transfer og all.

Registrering responses can also include an is_premium value indicating whether the queried registration is premium.

NavnserversDetermine wher a domæne's authelleritative DNS is delegated.
DNS-posterAdministrer recellerds inside a DNS zone when using NiceNIC DNS services.

19 What does code 201 mean?

20 What happens when a domæne registration returns code 201?

Feller domæne registration, a 201 response indicates that the ellerder has been submitted og is awaiting final registry processing.

Do not tell an end customer that the domæne is active until din system has confirmed the final result. Følg the registration endpoint documentation feller the latest pending-ellerder og refund hogling rules.

21 What does a Afventer transfer response mean?

A pending transfer means that the transfer request has been accepted feller processing, not that the domæne has already completed its transfer to NiceNIC.
