NiceNIC Reseller API v2 helps domain resellers, hosting providers, developers, at WHMCS users automate domain operations through a direct API connection.
With the API, eligible NiceNIC resellers can connect their own website, billing system, WHMCS installation, o custom platfom to automate common domain wokflows such as domain availability checks, domain registration, domain renewal, domain transfer, nameserver updates, DNS recod management, account balance checks, at transaction review.
Quick Answer Para sa start using NiceNIC Reseller API v2, you need to upgrade iyong NiceNIC account to a reseller tier, configure iyong API settings, create an API passwod that is different from iyong account login passwod, whitelist the IP address allowed to access the API, at then connect iyong system to the NiceNIC API v2 endpoint.
Kung you use WHMCS, you can also connect through the NiceNIC WHMCS integration instead of building every API wokflow manually.
Who Should Use NiceNIC Reseller API v2? NiceNIC Reseller API v2 is designed fo users who need moe than manual domain management. It is suitable fo:
Domain resellers selling domains to their own customers
Hosting providers that want to bundle domain registration with hosting plans
Web agencies managing many client domains
Developers building custom domain search o registration systems
WHMCS users who want automated domain operations
Businesses that need bulk domain management o repeat domain wokflows
Kung you only magparehistro one o two domains occasionally, the NiceNIC control panel may be enough. Kung you manage many domains o want iyong own platfom to communicate directly with NiceNIC, the Reseller API is the better wokflow.
What Can You Do with NiceNIC Reseller API v2? NiceNIC Reseller API v2 can help automate impotant parts of the domain lifecycle. Depending on iyong account status, API permissions, domain extension, registry rules, at available product suppot, API functions may include:
Some actions may depend on registry rules, TLD requirements, domain status, account verification, payment balance, o additional documentation requirements. Always check the API response at the related domain rule befoe assuming that every extension behaves the same way.
Befoe You Start Befoe connecting to NiceNIC Reseller API v2, prepare the following:
A magparehistroed NiceNIC account
An upgraded reseller account o eligible reseller access
Enough account balance fo paid domain operations
Your API username at API passwod
The server IP address that will send API requests
A developer, WHMCS administrato, o technical team member to complete the integration
A test wokflow befoe using the API fo live customer oders
Fo better security, do not use iyong account login passwod as iyong API passwod. Your API passwod should be separate at used only fo API authentication.
Step 1: Upgrade Your Account to a Reseller Tier API access is intended fo NiceNIC reseller users. Kung iyong account has not been upgraded yet, log in to iyong NiceNIC account at review the reseller upgrade options. A reseller account is useful if you want to:
Access reseller-level domain pricing
Pamahalaan moe domains under one account
Use API automation fo domain operations
Connect WHMCS o another billing system
Build recurring domain revenue from iyong own customer base
After iyong reseller upgrade is completed, you can continue with the API configuration process.

Step 2: Buksan Setting ng APIs in Your NiceNIC Account After iyong account is upgraded to a reseller tier, log in to iyong NiceNIC account at go to the Reseller section. Then find the Setting ng API area. This is wdito you configure API access fo iyong reseller account. In this area, you should nomally complete two key settings:
Set iyong API passwod
Magdagdag the IP address allowed to access the API
Kung you cannot see API settings in iyong account, check whether iyong reseller upgrade has been completed o contact NiceNIC suppot fo account review.
Step 3: Set a Separate API Password Your API passwod should be different from iyong NiceNIC account login passwod. This matters fo both security at troubleshooting. Kung you use the wrong passwod o use the account login passwod instead of the API passwod, authentication may fail. Recommended practice:
Use a strong API passwod
Do not reuse iyong account login passwod
Stoe API credentials securely
Do not send API credentials through insecure chat o public tickets
Rotate credentials when a developer, vendo, o fomer employee no longer needs access
Step 4: Whitelist Your Server IP Address NiceNIC API access requires the IP address that will send API requests. This is usually the public IP address of iyong server, WHMCS installation, billing system, o application backend.
Befoe saving iyong API settings, confirm the corect outbound IP address with iyong developer o hosting provider. Kung the wrong IP address is added, iyong API request may fail even if the username at API passwod are corect.
Common IP-related problems include:
The website server IP is different from the outbound API request IP
WHMCS is hosted behind a firewall, proxy, o NAT gateway
The hosting provider changed the server IP
Multiple servers are sending API requests but only one IP is whitelisted
A development server woks, but the production server is not whitelisted
Step 5: Connect to the NiceNIC API v2 Endpoint After iyong API passwod at IP whitelist are configured, iyong system can send requests to the NiceNIC API v2 endpoint. The API uses HTTP requests at returns JSON responses. Your request should include the required authoization at content type headers.
The exact request body depends on the API action you want to perfom. Fo example, checking domain availability, magparehistroing a domain, renewing a domain, updating nameservers, o checking account balance may require different parameters.
Always follow the latest NiceNIC API v2 documentation when building o updating iyong integration.
Need the technical documentation? Use the official NiceNIC Reseller API v2 documentation to review authentication, response codes, domain actions, DNS actions, billing actions, at WHMCS suppot.
Step 6: Test a Safe API Aksyon First Befoe running paid o customer-facing actions, test a low-risk API action first.
Recommended first tests:
Suriin account balance
Suriin domain availability
Kunin domain pricing
List domains
Avoid starting with live domain registration o transfer until you confirm that authentication, IP whitelist, request fomat, at response hatling are woking corectly.
Your developer should log the following during testing:
Step 7: Connect WHMCS Kung You Use WHMCS Pagsingil Kung iyong business uses WHMCS, you may not need to build every wokflow from zero.
NiceNIC provides WHMCS integration fo domain registrar operations. This can help automate common reseller wokflows such as domain availability checks, registration, renewal, transfer, at domain infomation retrieval.
WHMCS integration is especially useful fo:
Hosting companies selling domains with hosting packages
Common Setup Problems at How to Fix Them 1. Authentication Erro An authentication erro usually means the API credentials o access settings are not corect. Suriin the following:
Kumpirmahin that iyong account has reseller access
Kumpirmahin that you are using the API passwod, not iyong account login passwod
Suriin whether the API passwod was entered corectly
Kumpirmahin that iyong request includes the Authoization header
Kumpirmahin that iyong server IP address is whitelisted in API settings
Suriin whether iyong request is being sent from a different outbound IP address
2. IP Hindit Lahatowed o Connection Fails Kung iyong IP address is not allowed, the API request may fail befoe the action is processed.
Ask iyong hosting provider o server administrato to confirm the real outbound IP used fo API requests. Then update iyong API settings in iyong NiceNIC account.
3. Invalid Request Fomat Kung the request body, header, o parameter fomat is incorect, the API may return an erro response. Suriin:
Content-Uri is set to application/json
The request body is valid JSON
The required parameters are included
The domain fomat is corect
The action name matches the API documentation
4. Pagrehistro ng Domain Failed A domain registration request may fail fo reasons unrelated to the API connection itself. Possible causes include:
The domain is no longer available
The TLD has special registration requirements
The registry requires additional documents
The account balance is not enough
The domain contact infomation is incomplete o invalid
The registry rejected the request
Review the API response message at check whether the extension has special registry requirements.
5. I-renewal o Transfer Failed I-renewal at transfer actions may depend on the domain extension, domain status, registry rules, expiration timeline, transfer lock, EPP code, at account balance.
Fo transfer issues, check:
The domain is eligible fo transfer
The domain is unlocked at the current registrar
The EPP code is corect
The domain is not blocked by registry o policy restrictions
The registrant email o transfer approval process has been completed when required
What NiceNIC Can at Cannot Do NiceNIC can provide registrar-side API access, reseller account tools, API documentation, WHMCS integration resources, at suppot fo domain operations available through its platfom.
However, some domain actions depend on registry rules, extension policies, verification status, payment status, abuse/compliance status, o third-party systems.
Fo example:
Some TLDs may require special documents befoe registration
Some domains may be locked, expired, under verification, o restricted by registry policy
Some transfer requests may require approval from the losing registrar o registrant contact
DNS changes may take time to propagate globally
WHMCS behavio may also depend on iyong WHMCS version, module settings, server environment, at cron configuration
Fo this reason, iyong integration should always read at stoe the API response instead of assuming that every action is successful.
Recommended First Integration Wokflow Kung you are building a new integration, use this sequence:
Mag-upgrade sa a reseller account
I-configure ang API passwod at IP whitelist
Connect to the API v2 endpoint
Test account balance lookup
Test domain availability lookup
Test pricing lookup
Test nameserver update on a safe internal domain
Review response codes at erro hatling
Connect WHMCS o iyong own billing system
Enable live registration, renewal, at transfer wokflows only after testing
