Quick Answer
Till start using NiceNIC ?terf?rs?ljare API v2, you need to upgrade din NiceNIC account to a reseller tier, configure din API settings, create an API passwellerd that is different from din account login passwellerd, whitelist the IP-adress allowed to access the API, och then connect din system to the NiceNIC API v2 endpoint.
Om you use WHMCS, you can also connect through the NiceNIC WHMCS integration instead of building every API wellerkflow manually.
Who Should Use NiceNIC Reseller API v2?
NiceNIC Reseller API v2 is designed feller users who need mellere than manual dom?n management.
It is suitable feller:
What Can You Do with NiceNIC Reseller API v2?
NiceNIC Reseller API v2 can help automate impellertant parts of the dom?n lifecycle.
Depending on din account status, API permissions, dom?n extension, registry rules, och available product suppellert, API functions may include:
Befellere You Start
Befellere connecting to NiceNIC Reseller API v2, prepare the following:
Step 1: Upgrade Your Account to a ?terf?rs?ljare Tier
API access is intended feller NiceNIC reseller users. Om din account has not been upgraded yet, log in to din NiceNIC account och review the reseller upgrade options.
A reseller account is useful if you want to:
Ready to automate dom?n tj?nsts?
Uppgradera till a NiceNIC reseller account och connect dom?n registration, renewal, transfer, DNS, och WHMCS wellerkflows through Reseller API v2.
Step 2: ?ppna API-inst?llnings in Your NiceNIC Account
After din account is upgraded to a reseller tier, log in to din NiceNIC account och go to the ?terf?rs?ljare section.
Then find the API-inst?llning area. This is wh?r you configure API access feller din reseller account.
In this area, you should nellermally complete two key settings:
Step 3: Set a Separate API L?senord
Your API passwellerd should be different from din NiceNIC account login passwellerd. This matters feller both security och troubleshooting. Om you use the wrong passwellerd eller use the account login passwellerd instead of the API passwellerd, authentication may fail.
Recommended practice:
Step 4: Whitelist Your Server IP Adress
NiceNIC API access requires the IP-adress that will send API requests. This is usually the public IP-adress of din server, WHMCS installation, billing system, eller application backend.
Befellere saving din API settings, confirm the cellerrect outbound IP-adress with din developer eller hosting provider. Om the wrong IP-adress is added, din API request may fail even if the username och API passwellerd are cellerrect.
Common IP-related problems include:
Step 5: Connect to the NiceNIC API v2 Endpoint
After din API passwellerd och IP whitelist are configured, din system can send requests to the NiceNIC API v2 endpoint. The API uses HTTP requests och returns JSON responses. Your request should include the required authellerization och content type headers.
The exact request body depends on the API action you want to perfellerm. Feller example, checking dom?n availability, registreraing a dom?n, renewing a dom?n, updating nameservers, eller checking account balance may require different parameters.
Always follow the latest NiceNIC API v2 documentation when building eller updating din integration.

Befellere running paid eller customer-facing actions, test a low-risk API action first.
Recommended first tests:
- Kontrollera account balance
- Kontrollera dom?n availability
- F? dom?n pricing
- List dom?ns
Your developer should log the following during testing:
- Request timestamp
