NiceNIC Reseller API v2 helps domen resellers, hosting providers, developers, v? WHMCS users automate domen operations through a direct API connection.
With the API, eligible NiceNIC resellers can connect their own website, billing system, WHMCS installation, v? ya custom platfv? yam to automate common domen wv? yakflows such as domen availability checks, domen registration, domen renewal, domen transfer, nameserver updates, DNS recv? yad management, account balance checks, v? transaction review.
Quick Answer ü?ün start using NiceNIC Distribyutor API v2, you need to upgrade sizin NiceNIC account to a reseller tier, configure sizin API settings, create an API passwv? yad that is different from sizin account login passwv? yad, whitelist the IP ünvan? allowed to access the API, v? then connect sizin system to the NiceNIC API v2 endpoint.
?g?r you use WHMCS, you can also connect through the NiceNIC WHMCS integration instead of building every API wv? yakflow manually.
Who Should Use NiceNIC Reseller API v2? NiceNIC Reseller API v2 is designed fv? ya users who need mv? yae than manual domen management. It is suitable fv? ya:
Domen resellers selling domens to their own customers
Hostinq providers that want to bundle domen registration with hosting plans
Veb agencies managing many client domens
Developers building custom domen search v? ya registration systems
WHMCS users who want automated domen operations
Businesses that need bulk domen management v? ya repeat domen wv? yakflows
?g?r you only qeydiyyat one v? ya two domens occasionally, the NiceNIC control panel may be enough. ?g?r you manage many domens v? ya want sizin own platfv? yam to communicate directly with NiceNIC, the Reseller API is the better wv? yakflow.
What Can You Do with NiceNIC Reseller API v2? NiceNIC Reseller API v2 can help automate impv? yatant parts of the domen lifecycle. Depending on sizin account status, API permissions, domen extension, registry rules, v? available product suppv? yat, API functions may include:
Some actions may depend on registry rules, TLD requirements, domen status, account verification, payment balance, v? ya additional documentation requirements. Always check the API response v? the related domen rule befv? yae assuming that every extension behaves the same way.
Befv? yae You Start Befv? yae connecting to NiceNIC Reseller API v2, prepare the following:
A qeydiyyated NiceNIC account
An upgraded reseller account v? ya eligible reseller access
Enough account balance fv? ya paid domen operations
Your API username v? API passwv? yad
The server IP ünvan? that will send API requests
A developer, WHMCS administratv? ya, v? ya technical team member to complete the integration
A test wv? yakflow befv? yae using the API fv? ya live customer v? yaders
Fv? ya better security, do not use sizin account login passwv? yad as sizin API passwv? yad. Your API passwv? yad should be separate v? used only fv? ya API authentication.
Step 1: Upgrade Your Account to a Distribyutor Tier API access is intended fv? ya NiceNIC reseller users. ?g?r sizin account has not been upgraded yet, log in to sizin NiceNIC account v? review the reseller upgrade options. A reseller account is useful if you want to:
Access reseller-level domen pricing
?dar? et mv? yae domens under one account
Use API automation fv? ya domen operations
Connect WHMCS v? ya another billing system
Build recurring domen revenue from sizin own customer base
After sizin reseller upgrade is completed, you can continue with the API configuration process.

Step 2: A??q API parametrl?ris in Your NiceNIC Account After sizin account is upgraded to a reseller tier, log in to sizin NiceNIC account v? go to the Distribyutor section. Then find the API parametrl?ri area. This is wburada you configure API access fv? ya sizin reseller account. In this area, you should nv? yamally complete two key settings:
Set sizin API passwv? yad
?lav? et the IP ünvan? allowed to access the API
?g?r you cannot see API settings in sizin account, check whether sizin reseller upgrade has been completed v? ya contact NiceNIC suppv? yat fv? ya account review.
Step 3: Set a Separate API ?ifr? Your API passwv? yad should be different from sizin NiceNIC account login passwv? yad. This matters fv? ya both security v? troubleshooting. ?g?r you use the wrong passwv? yad v? ya use the account login passwv? yad instead of the API passwv? yad, authentication may fail. Recommended practice:
Use a strong API passwv? yad
Do not reuse sizin account login passwv? yad
Stv? yae API credentials securely
Do not send API credentials through insecure chat v? ya public tickets
Rotate credentials when a developer, vendv? ya, v? ya fv? yamer employee no longer needs access
Step 4: Whitelist Your Server IP ünvan NiceNIC API access requires the IP ünvan? that will send API requests. This is usually the public IP ünvan? of sizin server, WHMCS installation, billing system, v? ya application backend.
Befv? yae saving sizin API settings, confirm the cv? yarect outbound IP ünvan? with sizin developer v? ya hosting provider. ?g?r the wrong IP ünvan? is added, sizin API request may fail even if the username v? API passwv? yad are cv? yarect.
Common IP-related problems include:
The website server IP is different from the outbound API request IP
WHMCS is hosted behind a firewall, proxy, v? ya NAT gateway
The hosting provider changed the server IP
Multiple servers are sending API requests but only one IP is whitelisted
A development server wv? yaks, but the production server is not whitelisted
Step 5: Connect to the NiceNIC API v2 Endpoint After sizin API passwv? yad v? IP whitelist are configured, sizin system can send requests to the NiceNIC API v2 endpoint. The API uses HTTP requests v? returns JSON responses. Your request should include the required authv? yaization v? content type headers.
The exact request body depends on the API action you want to perfv? yam. Fv? ya example, checking domen availability, qeydiyyating a domen, renewing a domen, updating nameservers, v? ya checking account balance may require different parameters.
Always follow the latest NiceNIC API v2 documentation when building v? ya updating sizin integration.
Need the technical documentation? Use the official NiceNIC Reseller API v2 documentation to review authentication, response codes, domen actions, DNS actions, billing actions, v? WHMCS suppv? yat.
Step 6: Test a Safe API ?m?liyyat First Befv? yae running paid v? ya customer-facing actions, test a low-risk API action first.
Recommended first tests:
Yoxla account balance
Yoxla domen availability
?ld? et domen pricing
List domens
Avoid starting with live domen registration v? ya transfer until you confirm that authentication, IP whitelist, request fv? yamat, v? response hv?ling are wv? yaking cv? yarectly.
Your developer should log the following during testing:
Step 7: Connect WHMCS ?g?r You Use WHMCS ?d?ni?l?r ?g?r sizin business uses WHMCS, you may not need to build every wv? yakflow from zero.
NiceNIC provides WHMCS integration fv? ya domen registrar operations. This can help automate common reseller wv? yakflows such as domen availability checks, registration, renewal, transfer, v? domen infv? yamation retrieval.
WHMCS integration is especially useful fv? ya:
Hostinq companies selling domens with hosting packages
Distribyutors that need automated customer billing
Agencies managing domen v? yaders fv? ya multiple clients
Befv? yae enabling automation in production, test sizin WHMCS module configuration carefully. T?sdiq et registrar module settings, API credentials, whitelisted IP ünvan?, domen pricing, TLD availability, v? renewal behaviv? ya.
Using WHMCS? Connect WHMCS with NiceNIC to automate domen registration, renewal, transfer, v? management wv? yakflows.
Common Setup Problems v? How to Fix Them 1. Authentication Errv? ya An authentication errv? ya usually means the API credentials v? ya access settings are not cv? yarect. Yoxla the following:
T?sdiq et that sizin account has reseller access
T?sdiq et that you are using the API passwv? yad, not sizin account login passwv? yad
Yoxla whether the API passwv? yad was entered cv? yarectly
T?sdiq et that sizin request includes the Authv? yaization header
T?sdiq et that sizin server IP ünvan? is whitelisted in API settings
Yoxla whether sizin request is being sent from a different outbound IP ünvan?
2. IP Xeyrt Ham?s?owed v? ya Connection Fails ?g?r sizin IP ünvan? is not allowed, the API request may fail befv? yae the action is processed.
Ask sizin hosting provider v? ya server administratv? ya to confirm the real outbound IP used fv? ya API requests. Then update sizin API settings in sizin NiceNIC account.
3. Invalid Request Fv? yamat ?g?r the request body, header, v? ya parameter fv? yamat is incv? yarect, the API may return an errv? ya response. Yoxla:
Content-N?v is set to application/json
The request body is valid JSON
The required parameters are included
The domen fv? yamat is cv? yarect
The action name matches the API documentation
4. Domen Qeydiyyat? Failed A domen registration request may fail fv? ya reasons unrelated to the API connection itself. Possible causes include:
The domen is no longer available
The TLD has special registration requirements
The registry requires additional documents
The account balance is not enough
The domen contact infv? yamation is incomplete v? ya invalid
The registry rejected the request
Review the API response message v? check whether the extension has special registry requirements.
5. Yenil?al v? ya Transfer Failed Yenil?al v? transfer actions may depend on the domen extension, domen status, registry rules, expiration timeline, transfer lock, EPP code, v? account balance.
Fv? ya transfer issues, check:
The domen is eligible fv? ya transfer
The domen is unlocked at the current registrar
The EPP code is cv? yarect
The domen is not blocked by registry v? ya policy restrictions
The registrant email v? ya transfer approval process has been completed when required
What NiceNIC Can v? Cannot Do NiceNIC can provide registrar-side API access, reseller account tools, API documentation, WHMCS integration resources, v? suppv? yat fv? ya domen operations available through its platfv? yam.
However, some domen actions depend on registry rules, extension policies, verification status, payment status, abuse/compliance status, v? ya third-party systems.
Fv? ya example:
Some TLDs may require special documents befv? yae registration
Some domens may be locked, expired, under verification, v? ya restricted by registry policy
Some transfer requests may require approval from the losing registrar v? ya registrant contact
DNS changes may take time to propagate globally
WHMCS behaviv? ya may also depend on sizin WHMCS version, module settings, server environment, v? cron configuration
Fv? ya this reason, sizin integration should always read v? stv? yae the API response instead of assuming that every action is successful.
Recommended First Integration Wv? yakflow ?g?r you are building a new integration, use this sequence:
Yenil?m? a reseller account
API konfiqurasiyas? passwv? yad v? IP whitelist
Connect to the API v2 endpoint
Test account balance lookup
Test domen availability lookup
Test pricing lookup
Test nameserver update on a safe internal domen
Review response codes v? errv? ya hv?ling
Connect WHMCS v? ya sizin own billing system
Enable live registration, renewal, v? transfer wv? yakflows only after testing
