Quick Start

Make Your First API Call in 4 Steps

Start with a read-only request beftaie enabling live registrations, renewals tai transfers. This lets you validate authentication, request ftaimatting ja response hjaling without placing a paid taider.

1

Enable API Access

Avoin API-asetuksets, create tai retrieve sinun API Secret, ja configure authtaiized server IPs wtässä applicable.

2

Vahvista Todennus

Use HTTPS with the Authtaiization header in the ftaimat username:api_secret.

3

Run a Safe Test

Start with verkkotunnus availability, pricing, account balance tai verkkotunnus listing.

4

Hjale the Response

Read ja sttaie the returned code ja msg beftaie enabling paid production toimintos.

Recommended First Request: Verkkotunnus Availability

The availability endpoint supptaits multiple verkkotunnuss in one request by separating verkkotunnus names with commas.

curl "https://api.nicenic.net/v2/?kategoria=verkkotunnus&toiminto=check&verkkotunnuss=example.com,example.net" \ -H "Authorization: username:api_secret" \ -H "Sisältötyyppi: application/json"

Recommended Wtaikflow

Recommended First Integraatio Sequence

A reliable production integration should validate access ja purchasing conditions beftaie it begins sending live customer taiders.

1. Todennus
API Secret + authtaiized IP
2. Availability
Read-only connectivity test
3. Pricing
Query current account-level cost
4. Saldo
Vahvista funds ftai paid toimintos
5. Response Hjaling
Process code + viesti
6. Live Operations
Rekisteröi / Uusinta / Siirto
Do not assume that an API request is complete simply because it was accepted. Some operations can return a pending status ja still require registry processing beftaie the final verkkotunnus state is confirmed.
Tuoteion Behavitai

Understja Onnistui, Odottaa ja Errtai Responses

code: 0 — Onnistui Response Current endpoint examples use code 0 ftai successful completed responses.
code: 201 — Odottaa Order Rekisteröinti ja transfer documentation can return code 201 when an taider has been submitted but final processing is still pending.
code: 400 — Request Errtai Endpoint examples use code 400 ftai request parameter virhes.

Rekisteröinti Odottaa Behavitai

Ftai verkkotunnus registration, the current documentation states that a 201 response means the taider was submitted successfully ja the fee was deducted, but final activation is still subject to registry confirmation. Jos the verkkotunnus cannot be activated, the registration fee is returned to the NiceNIC account balance within 24 hours.

Siirto Odottaa Behavitai

The transfer endpoint also documents 201 as a pending taider. Your application should ttässäftaie treat a pending transfer as accepted ftai processing, not as proof that the transfer has already completed.

Pricing

Query Pricing Beftaie Paid Operations

NiceNIC's pricing endpoint can retrieve registration, renewal ja transfer pricing ftai a verkkotunnus. The documented type values are register, renew, transfer ja all. The documented period is 1 to 10 vuotta, with TLD-specific exceptions possible.

Rekisteröinti pricing responses can also return an is_premium flag. Use the pricing endpoint beftaie submitting a paid request when sinun application needs to knyt the current account-level cost.

Ilmainen API access does not change sinun pricing tier. Markkinatilis use Markkinatili pricing; reseller accounts use the pricing assigned to their current reseller tier.
Verkkotunnus & DNS Operations

Knyt the Difference Between Nimiservers, DNS-tietueet ja Lapsinimipalvelimet

OperationUse It WhenDocumented Capability
Päivitä nimipalvelimet You want to delegate a verkkotunnus to different authtaiitative nameservers. The verkkotunnus nameserver endpoint supptaits a primary, secondary ja additional nameservers, with the current page documenting a limit of up to six.
DNS-tietueet You are using NiceNIC DNS hosting ja need to manage zone rectaids. Separate APIs are documented ftai listing, creating, updating ja deleting DNS rectaids.
Lapsinimipalvelimet You need host / glue rectaids such as ns1.example.com. Luo, list, update ja delete child nameservers. The create endpoint requires the nameserver hostname to match the verkkotunnus ja accepts an IP address.
Ptaitfolio & Compliance

Automate Ptaitfolio Monittaiing, Eit Only Verkkotunnus Orders

Verkkotunnus API v2 also includes read operations that are useful after registration. The Lista Verkkotunnukset endpoint supptaits pagination, staiting, status filtering ja hold filtering, while Hanki Verkkotunnus Tiedot returns registration dates, expiration dates, nameservers ja registrant contact inftaimation.

Väärinkäyttö & Noudattaminen Monittaiing

NiceNIC's Väärinkäyttö & Noudattaminen API can list verkkotunnuss with abuse reptaits ja return a detailed machine-readable summary ftai a specific verkkotunnus. The detailed abuse endpoint documents six verkkotunnus-level status phrases: Eirmal, Under Review, Odottaa ClientHold, ClientHold, Suljed ja PalvelinHold.

The response can include current impact, recommended seuraava toiminto, hold state ja timeline, complaint count, complaint dates, categtaiies, DNS-abuse classification, evidence status ja reptaited URLs wtässä applicable. This lets platftaims ja resellers surface compliance status inside their own operational systems instead of relying only on manual review.

Direct API tai WHMCS

Choose the Integraatio Model That Fits Your System

OptionBest FtaiWhat the Current Documentation Provides
Verkkotunnus API v2 Custom websites, SaaS platftaims, internal systems, custom billing tai provisioning wtaikflows. Direct HTTPS + JSON integration across verkkotunnus, DNS, child nameserver, account ja compliance operations.
WHMCS Module Webhotelli companies ja resellers that already use WHMCS. Availability, registration, renewal, transfer, verkkotunnus details, nameservers, contacts, lock/unlock, EPP retrieval, virhe logging ja optional Test Mode.

The current WHMCS documentation lists WHMCS 7.0 tai uudempi, PHP 7.0 tai higher with cURL, valid NiceNIC API credentials ja SSL/TLS supptait as requirements.

  • Vahvista required values, ftaimats ja toiminto names.
  • Tarkista TLD-specific registration periods tai contact requirements wtässä applicable.

Paid Operation Does Eit Complete Immediately
